VPN Protocols & Routes: Technical Reference

Break down a connection into stages

When you open a website, the client doesn't hand the page directly to the protocol. The app identifies the destination, the device resolves its domain name, and routing rules determine whether traffic goes through a proxy. Proxied traffic passes through the client and local network to an entry point, then reaches the destination website through the server. Responses travel back along the route. A page may also load images, scripts and resources from other domains, so a page that won't load doesn't necessarily mean a protocol failed to connect. Start by identifying whether the failure is in name resolution, connection setup, forwarding or content loading.

A protocol mainly defines how the client and server identify requests, authenticate and transfer data. It can affect the handshake, data encapsulation, connection reuse and how a connection responds to network changes. It cannot, by itself, determine your carrier's route, the exit location or how quickly a website responds. The same protocol can perform very differently over different routes, while different protocols may both slow down behind the same congested exit. Judging a route by protocol name alone confuses routing issues with implementation details.

Evaluate first response, sustained throughput and reliability separately

Fast connection setup means less waiting before the app starts receiving content—useful when frequently opening web pages or making repeated API calls. Sustained throughput is about how smoothly a connection transfers data once it's established, which matters for downloads and long streams. Reliability also includes response-time variability, frequent reconnects and recovery after a network switch. One setup may open pages quickly but be limited by exit capacity during long transfers. Another may download steadily but take longer on the initial handshake. These aren't the same measure of “speed.”

Keep the device, access network, destination service and routing mode consistent when testing. First compare the protocols available for the same route in your panel; then compare routes using the same protocol. Avoid changing the region and client settings at the same time. Test pages, meeting apps or files you actually use, and note when issues occur. Different destinations may use different exit routes, so a single speed-test result only reflects its own connection path—not every app.

Separate protocol capabilities from service commitments

A feature described in a protocol specification isn't necessarily enabled on both the current client and server. Datagram forwarding, connection migration and multiplexing, for example, may require compatible software support and server configuration. Check the subscription details in your panel, the options available in your client and the route description. Don't add parameters just because they seem more advanced, and don't assume this service offers a particular dedicated route or transport based on a general tutorial. Importing a subscription from the correct source is more reliable than manually combining unverified settings.

VPNQB lists coverage in 100+ countries with 190+ routes. See the route list for available regions and entry points. These figures describe the range of choices, not a performance guarantee for every route or destination. This guide doesn't rank protocols, either: the right setup must be reachable on your network, work with your target app and suit your device. Record comparisons as observations under specific conditions, not as lasting conclusions based on one successful session.

Before you compare

Make sure your subscription is up to date, your device clock is correct and the destination service is responding. Record “connected” and “the app works” separately; don't rely on the client's connection icon alone.

Shadowsocks: a straightforward proxy boundary

Shadowsocks is an encrypted proxy protocol that forwards app traffic between a client and server. It typically doesn't have the interface and routing features of a full network tunnel. How apps send traffic through the proxy depends on the client—for example, through a system proxy, virtual network interface or routing rules. Seeing a VPN indicator on your device doesn't mean the protocol itself is a network-layer tunnel; the indicator may simply show that the operating system lets the client handle traffic. Understanding the distinction helps explain why some apps use the proxy while others don't.

The experience depends on the encryption method, implementation quality and transport path. Simpler encapsulation can reduce processing overhead, but that doesn't mean it uses less battery on every device. Hardware encryption support, whether the client continuously scans traffic and the complexity of its rules can all affect resource use. In practice, the encryption method and credentials must match the server. A client may let you save a configuration with valid credentials but an incompatible encryption method, yet the requests won't succeed.

Check TCP traffic and UDP datagrams separately. A website working over TCP doesn't prove that apps relying on UDP will work too; server forwarding, client mode and the access network can all limit datagram traffic. If a meeting app connects but has audio problems while web pages load normally, first check the transport the app uses and whether the client supports datagrams. Don't replace every route right away. If a feature isn't available in your user panel, don't assume it's supported just because you can change a local setting.

VMess: authentication and encapsulation depend on the implementation

VMess has its own protocol structure for request authentication and data encapsulation, and can be combined with different transport methods. When comparing setups, distinguish VMess from the transport carrying it. The same protocol may use a direct streaming connection or additional encapsulation. Whether the outer layer provides secure transport, uses a forwarding entry point or adds negotiation can affect connection time and compatibility. Don't generalize the pros and cons of one specific setup to every VMess configuration.

Authentication failures may be related to subscription parameters, client compatibility or the device clock. A significantly incorrect clock can affect authentication and security checks that rely on time, but it isn't the cause of every failure. First enable automatic time synchronization, refresh your subscription and confirm that your client can read the configuration from your panel. Avoid copying fields from an old configuration based on guesswork. A configuration one client can import may be interpreted differently by another.

Additional encapsulation may suit a particular entry-point deployment or transport environment, but it adds processing steps. If a connection is established but pages respond slowly, compare other available setups in the same region to see whether the delay comes from entry-point negotiation or later transport. If only the first visit is slow and later requests are steady, check connection reuse and DNS resolution first. If the entire session is slow, consider route capacity, the destination's response and device resources—not just authentication.

Use cases and common misconceptions

For everyday browsing and general app use, there's no need to change a working setup just to use a different protocol name. The simplicity of Shadowsocks and the encapsulation options in VMess each suit different conditions. What matters is whether your client imports the configuration correctly, whether the traffic your app needs is routed through it and whether the exit route suits the destination region. If you regularly switch devices, factor in compatibility and subscription maintenance—not just how one connection feels.

When troubleshooting, describe the issue more precisely: “the client can't connect,” “the client connects but pages fail” or “the transfer drops partway through.” The first points more toward parameters, the entry point or authentication. The second may involve routing rules, DNS or the destination service. The third calls for checking network fluctuations, session persistence and exit congestion. If you label all three “protocol instability,” even a temporary fix after changing the configuration won't tell you which part was actually corrected.

Configuration maintenance: what to change and what not to

Get and update your subscription through the user panel. For details on finding, importing and resetting the link, see How VPN Subscription Links Work. Don't show the full subscription in public discussions or screenshots.

What a secure Trojan connection requires

Trojan typically sends proxy requests over a secure TLS connection. The client first establishes a secure session that meets the configuration requirements, then authenticates the proxy request and forwards it. TLS protects the transport and verifies the server's certificate identity; Trojan credentials determine whether the server accepts the proxy request. These are separate checks. A valid certificate doesn't prove the proxy credentials are correct, and valid credentials can't fix a mismatched certificate name or a problem with the device's trust settings.

The server address, the name used for TLS and the name covered by the certificate must match the relationships specified in the configuration. A subscription may specify separate connection and server names. Don't change them just because they look different. If your panel has provided a complete configuration, import it as is. For certificate errors, first check the device date and whether the subscription has expired or been manually changed, then check client compatibility. Disabling certificate verification isn't a routine fix.

Establishing TLS adds negotiation overhead, but it doesn't restart from scratch for every app request. Clients may reuse existing connections, and secure sessions may support resumption; the actual effect depends on the implementation and server policy. Apps that frequently open short-lived connections may be more affected by the initial negotiation, while route quality and exit capacity usually matter more for long transfers. Testing only a cold start can understate performance with an established session; testing only a warmed-up connection can hide the initial wait.

Lightweight VLESS semantics don't mean complete security

VLESS is designed with a leaner request structure and authentication model. It doesn't itself provide the same data-encryption layer as some encrypted proxy protocols, so its security depends on the transport configuration around it. Any discussion of VLESS should also specify the outer secure transport and client implementation. Calling it “lightweight” isn't enough to conclude that it's faster, safer or more power-efficient. Ignoring transport protection also gives a misleading picture of where it can be used.

VLESS setups can differ in transport and negotiation settings, so client support for the relevant fields matters. A successful import only means the text was accepted; it doesn't guarantee that every parameter behaves as expected. If routes disappear after a subscription update or the client reports unsupported fields, first check the client's source and supported features, then consult your panel. Don't piece together fields from tutorials for other services. Parameters with the same name may depend on a specific setup and aren't necessarily interchangeable.

Fewer protocol-layer operations can reduce some processing, but outer secure connections, rule matching and data copying still take resources. A VLESS setup with complex transport may not be lighter than a Trojan setup with a mature implementation. Memory use and device heat may also come from client logs, the number of connections or app activity. For a fair comparison, keep the entry point, destination and test consistent, and record the complete setup—not just the protocol name.

Why switching routes won't fix certificate problems

If an error clearly points to the certificate chain, server name or device clock, switching regions at random may only make the symptom disappear temporarily; it doesn't prove the original problem is fixed. Keep a note of the error type, restore the subscription's original parameters and retry with normal verification enabled to determine whether a single configuration is at fault. If several secure connections fail at once, check the device's trust store, local security software and network sign-in status. An incomplete sign-in on shared Wi-Fi can also interfere with normal connections.

Protocol encryption and a service's privacy policy are separate matters, too. TLS can protect a particular part of the connection, but it can't replace account security, secure connections to destination websites or service policies. VPNQB describes its privacy practices as “anonymous, no logs.” Read the Privacy Policy for details. Don't treat a protocol name as absolute protection for every activity, or weaken normal identity checks to reduce connection delays.

UDP transport doesn't mean app data is unreliable

Hysteria2 and TUIC are both associated with QUIC transport. QUIC runs over UDP but can provide secure sessions, reliable streams and congestion control at a higher layer. So “uses UDP” doesn't mean web content can randomly go missing or that packet loss doesn't need to be handled. QUIC implements some traditional connection functions differently, which can make stream and connection management more flexible. Whether that helps depends on how well the client, server and access network work together.

With traditional TCP, losing a segment can block later data in the same byte stream. QUIC can reduce this kind of delivery-level blocking between independent streams, but a reliable stream still has to wait for missing data, and all streams share the same route capacity. Congestion control still affects overall sending speed, so “less head-of-line blocking” doesn't mean packet loss has no impact. Dependencies between app requests can also leave an entire page waiting for a resource that hasn't arrived.

QUIC connection IDs and migration mechanisms provide a technical basis for maintaining connections through network changes, but they can't guarantee a seamless app experience on their own. The result also depends on whether the client allows migration, how the server validates the new path, device background permissions and the state of the NAT mapping. Some apps actively reconnect after a network switch. Check whether the app you actually use keeps responding; don't assume a meeting or download will continue just because the client still shows a connection.

Hysteria2: sending strategies must suit the actual route

Hysteria2 implementations can use sending strategies suited to particular route conditions, with settings that may include expected bandwidth and congestion control. Bigger values aren't necessarily better: declaring more capacity than the route can provide may increase queuing, packet loss and retransmissions, and affect other apps on the same access network. Automatic detection and explicit settings each have their own assumptions, so use the configuration provided by your panel first. This guide doesn't give a one-size-fits-all bandwidth value; without route-specific information, it wouldn't be reliable advice.

On a fluctuating route, a more proactive sending strategy may improve some sustained transfers, but it can't create exit capacity that isn't there. On a weak Wi-Fi connection, sending more can make interactive latency worse. Assess page response, meeting audio and device load together; don't look only at download speed. If a large transfer improves but other apps become noticeably sluggish, consider whether it has filled the queue rather than treating that as an acceptable side effect of better performance.

TUIC: app needs determine how streams and datagrams are handled

TUIC also uses QUIC to carry proxy traffic. Implementations can handle streams and datagrams differently. Stream-based requests need complete, ordered delivery, while real-time audio and video may prioritize fresh data; retransmitting expired data might not help. How the protocol forwards datagrams and whether certain content uses reliable streams affects the trade-off between delay and data loss. A client's display name may not explain all this, so check the configuration details and how your app behaves.

QUIC setups are worth comparing on networks that support UDP properly. On networks that restrict or interfere with UDP, they may have more trouble connecting than TCP setups. A common sign is that a TCP configuration works while a QUIC configuration stays stuck connecting. In that case, restore service with another transport offered by your panel and then check whether the local access network allows the relevant traffic. This is more useful than repeatedly changing authentication fields.

Don't infer guarantees from transport type

QUIC and TCP each suit different environments. A successful switch shows that this setup works under current conditions, not that it's better on every network. A failure doesn't prove the protocol design is flawed.

On mobile devices, also consider the background activity needed to keep UDP sessions alive. A client may send keepalives to maintain connection state and network mappings, waking the device to process them. If battery use during extended standby is noticeably high, check background rules, keepalive behavior and signal strength—not just another QUIC setup that may be equally active. Results on a stable network also don't necessarily apply when commuting through frequent network changes.

Connection delays can come from multiple negotiations

A new proxy connection may involve DNS resolution, an underlying connection, security negotiation, proxy authentication and a connection to the destination. A delay at any stage can make it look as though the app is stuck. The time shown in the client may not cover every stage, and the time shown by an app may include rendering. When comparing connection speeds, distinguish cold starts, existing proxy sessions and destinations with cached resources. Don't rank results from different conditions together.

Connection reuse reduces repeated negotiation on later requests, but it comes with trade-offs. Sending several requests over one existing connection can reduce the number of connections and handshakes. If that underlying connection has a problem, more requests may be affected at once. Whether reuse helps depends on the protocol implementation, app behavior and network conditions. If the first connection is a little slow but later requests are steady, keep observing. If all requests stall together after reuse, check whether the underlying session is still working.

CPU, memory and logging are different kinds of overhead

Encryption and decryption use processing power; traffic buffers and connection state take memory; and rule matching, DNS and logging also consume resources. The cost depends on the device hardware, operating system scheduling and client implementation. Brief heat under heavy throughput doesn't necessarily indicate a protocol problem. Persistent heat while idle is a stronger reason to check reconnect loops, verbose logging or background app requests. Comparing process memory alone can't tell you which protocol uses less battery: memory may be cached rather than tied to ongoing computation.

Keep app activity consistent when testing resource use. Browser tabs, cloud sync, app updates and video playback can add load and affect your results. First stop large transfers unrelated to the test, then note the client's connection status and the system's battery activity. If the client keeps logging the same error, fix its cause first; repeated failed connections often use more resources than maintaining a healthy session. Return logging to its normal level after troubleshooting rather than leaving verbose output on.

Mobile network battery use goes beyond encryption

Wireless communication itself uses power on mobile devices. Maintaining a connection with a weak signal, switching networks frequently and repeatedly waking the radio can all increase battery use. Frequent keepalives, reconnects or background app requests from a proxy client can make the impact more noticeable. A protocol that feels light on a desktop isn't necessarily suitable for long periods of standby on a mobile device. Assess stationary Wi-Fi and mobile networks separately.

A sensible way to reduce battery use is to cut unnecessary activity first, then compare protocol setups. Check for unavailable routes that keep reconnecting, make sure verbose logging isn't left on, and see whether apps are continually downloading in the background. Power-saving restrictions may also pause the client, forcing it to reconnect when you return to the app. Don't blindly turn off every system power-saving feature to keep a connection alive. First determine whether a background permission is causing interruptions or whether the route session itself is failing, then adjust only the permissions recommended by the client.

iOS network extensions and Android background management work differently; don't assume a desktop-style always-on process. For installation and import steps, see the Quick Start Guide. iPhone users can also read the iOS Setup Guide for Beginners. Menus can change between platforms and versions, so this page focuses on how to assess the issue rather than guessing at menu locations or client versions.

How to reach a battery-use conclusion you can verify

Record whether the device was idle, the network signal was stable, content was playing and the client reconnected. Observe normal daily use first, then switch to another setup offered by your panel under similar conditions. If battery use improved because you turned off background sync, don't credit the protocol. If the issue occurs only with a weak signal, focus on the access network. Choose a setup that balances connection recovery and battery life; you don't need to chase the smallest resource figure or treat occasional heat as a long-term pattern.

Region labels usually describe the exit, not the entire route

A route labeled “Tokyo” or “Singapore” usually identifies the exit region or node location, but it doesn't necessarily mean your device connects directly to that city. The client connects to an entry point first; the entry may forward traffic to an exit, which then reaches the destination service. The entry and exit may be on different networks, and a route name may not list every intermediate hop. When comparing regions, separate the exit location your app needs from how well your device can reach the entry point. Even with a suitable exit, a poor entry route for your current network can mean a poor experience.

A direct route usually means your device connects straight to the destination proxy server, with no additional relay arranged by the service. This is easier to understand, with fewer distinct processing steps, but route quality depends on connectivity between your local access network and the remote network. A nearby location doesn't necessarily mean a shorter network path. Carrier routing, interconnection capacity and exit policies can send traffic through a surprisingly long route.

Relaying adds a hop, but can improve the route

A relay sends requests through an additional entry point to an exit, aiming to make better use of the access network and subsequent transport path. It adds forwarding steps, but if the entry is easier to reach and the later path is more stable, the overall experience may be better than a direct connection. On the other hand, a congested relay entry or limited downstream capacity can add delays. More hops don't automatically mean slower, and “relayed” doesn't automatically mean more reliable.

A relayed route depends on the entry, the downstream path and the exit. A good connection from your device to the entry only confirms that the first segment is reachable; problems reaching the destination from the exit will still affect the app. If the client connects but a website keeps loading, the issue may be downstream or at the exit rather than on your local network. If several exits behind the same entry have problems, check for a shared point of failure. If only one destination fails, check its response, regional requirements and DNS results.

A dedicated route describes the path, not the protocol

A dedicated route generally refers to a transport path with specific resource arrangements by the service provider. Check the route description for its access method, degree of sharing and service boundaries. Dedicated routes aren't mutually exclusive with Trojan, VLESS or QUIC: the former describes path resources, while the latter describe how the client and server transfer data. A protocol name doesn't prove that a route is dedicated, and a region label doesn't prove a particular network tier. Check your panel for VPNQB's route details; this guide doesn't make new support promises based on general terminology.

Even when a dedicated path is used downstream, local Wi-Fi, access to the entry and the route from the exit to the destination may still fluctuate. A dedicated route can't replace a strong local signal or ensure identical performance in every app. When choosing a route, find out which segment it improves and test whether your apps benefit. For interactive meetings, steady round-trip time and low jitter may matter more; for file transfers, sustained capacity and the exit path deserve more attention.

Consider the return path as well as the outbound path

Network routes are directional: requests and responses may travel over different interconnections. Smooth uploads but variable downloads don't necessarily indicate a client configuration problem. Conversely, normal downloads with poor meeting audio may point to the upstream path or local queuing. Reaching the entry point from the client doesn't prove that the return path and exit route are working properly. During troubleshooting, check outgoing traffic, incoming traffic and interactive responses separately instead of reducing every issue to a single route status.

When checking the route list, start with the destination region, then choose an entry setup based on the app you use. You can keep alternatives for frequently used regions, but try to choose a backup that doesn't rely on exactly the same shared entry. When traveling for work, network conditions can change substantially; see Choosing a Network Setup for Business Travel for more on hotel Wi-Fi and cross-border work. Recheck your route when the access network changes instead of assuming a one-time choice will always work.

Packet loss has more than one cause

Packet loss can occur on Wi-Fi, in router queues, at network interconnections or on the destination side. When a wireless signal is disrupted, devices may retransmit or adjust their sending rate; apps may feel slower or less stable without showing a clear error. When a queue runs out of capacity, devices drop some data to ease congestion and reliable transports then try to recover it. Treating all packet loss as a route fault overlooks the local network, a common source of problems, and can make random changes in signal quality look like an improvement after switching protocols.

A network device that doesn't respond during route diagnostics isn't necessarily failing to forward traffic. Some devices give diagnostic responses low priority or don't respond to certain probes at all. If an intermediate hop looks abnormal but the destination and app still respond normally, don't assume that hop is where packets are being lost. Diagnostic tools offer clues; app behavior and the endpoint are more important for assessing service impact. Don't draw a conclusion based solely on how one intermediate node appears.

Queuing can make a connection feel unresponsive even while it's still connected

When demand exceeds the available link capacity, data starts queuing. Downloads may keep progressing while meeting audio arrives late, often because a large transfer has filled a shared queue. The client may still show a connection because the connection itself hasn't dropped. Pause background transfers and cloud sync, then see whether interactive apps recover. This is a useful way to distinguish local queuing from congestion farther away. Switching to a protocol that sends more aggressively may make the delay worse.

Sustained throughput and responsiveness have different priorities. A file transfer can tolerate some waiting as long as the file eventually arrives; a meeting needs current audio and video on time, and late data can't fully restore the experience. Reliable streams retransmit data to preserve completeness, while real-time apps may tolerate some loss to keep moving. Both the transport and app behavior shape the result. “Fast download” doesn't mean “good call,” and an occasional audio glitch doesn't prove the entire route is unusable.

Peak hours call for another look at shared resources

If several routes slow down at the same time, the access network, shared entry or interconnection capacity may be under greater demand. If only one exit slows down, the issue may be closer to that exit or its route to the destination. First compare different entries on the same access network, then compare the same destination through different exits to narrow down the cause. One evening's failure doesn't establish long-term service performance, and a smooth daytime test doesn't explain every time of day. Keep the time of each observation.

Congestion control adjusts sending in response to route conditions to avoid keeping the network saturated. Implementations may respond differently to fluctuations, so protocols can perform differently on the same route. But no protocol can overcome the route's actual capacity limits, and more aggressive sending may not suit a shared access network. If one setup speeds up downloads but slows every other app, include that trade-off in your choice. A stable experience depends on concurrent apps, not giving one transfer all available capacity.

The hidden effects of encapsulation and path MTU

Additional encapsulation takes up packet space, and the effective packet size a route can carry may change across networks. If small requests work but large pages or uploads stall, path MTU and fragmentation are worth checking—but don't immediately enter a fixed value you found online. Clients handle traffic differently, and the right setting may be in a different place. Start with the panel and client defaults, then try another access network or restore the original settings to see whether the encapsulated path is involved.

Secure transport, virtual interfaces and datagram encapsulation can stack up, causing problems that appear only in certain apps or with large requests. Distinguish a destination server rejecting an upload from an app timing out or network transmission stalling. The first usually comes with an app-level message; the others need to be assessed using client logs and tests to other destinations. If uploads fail on just one website, don't change the global MTU right away. If several destinations fail on similar transfers and work again on another access network, investigate the route conditions further.

Narrow the problem down one step at a time

On the same device, switch access networks; on the same network, try another entry; on the same entry, try another destination. Each test answers a different question. Change only one condition at a time and keep the last working configuration. That way, a temporary recovery won't be mistaken for finding the root cause.

When contacting support, include your access network, region, time of the issue, target app and error type; this is more useful than simply saying “it's slow.” You can attach a checked excerpt from the logs, but remove subscription links, credentials and account details. Contact support through user panel tickets. Logs can help identify the connection stage, but aren't a reason to share your full configuration publicly.

Browsing, AI tools and API requests

Everyday browsing depends more on first response, DNS resolution and parallel resource loading. Start with a setup that connects reliably on your current access network, and check how smoothly pages open and switch before changing protocols. AI tools and long-running API requests also depend on destination region, account permissions and server sessions. If the page loads but a request ends partway through, proxy authentication isn't necessarily the issue. First check whether the destination service allows your account and region, then see whether the client or network is ending the connection while it waits.

If an AI page lets you sign in but some content doesn't appear, check whether the failed request is a main request or comes from a secondary domain. Review whether routing rules send related requests along different paths. Changing the routing mode can be useful as a short-term test, but don't keep sending all traffic a different way before you know why. For recurring request errors, note whether the destination's message and the client's error occur at the same time. If the app explicitly denies access, changing protocols won't resolve the service's access requirements.

Test streaming, downloads and meetings separately

Streaming depends on the region, account, content catalog and sustained transport all working together. The right exit region doesn't guarantee that a platform will accept the exit, and a protocol name can't guarantee that content will be available. After playback starts, check whether buffering continues, video quality stays consistent and playback recovers after seeking. For background on catalogs and picture quality, see Streaming Availability Guide and Netflix Regional Catalogs and 4K Streaming. This guide focuses on assessing transport and doesn't make unverified claims about access.

For downloads, assess sustained performance rather than just startup. For meetings, check outgoing and incoming audio and how quickly participants respond. If a meeting has problems but web pages work, check datagram support and local upload queuing first. If every app is slow, compare route entries and access networks. If you travel for work, retest your usual apps whenever the network changes. On shared Wi-Fi, complete the network sign-in before treating a client connection failure as an expired subscription.

Follow a troubleshooting sequence you can retrace

First pause background transfers unrelated to the issue and make sure the device clock and access network are working. Then update your subscription through the user panel. Keep the default settings and retry the route that last worked. If it fails, try another entry offered in the panel. Next, identify whether the client can't connect, the destination fails after connection or the transfer breaks midway. Keep any configuration that restores service before making further comparisons. Don't change the protocol, region, routing rules and security checks all at once after each failure.

If only one route still fails after a subscription update and the others work, focus on that route's configuration and entry point. If none of the routes connect, first check network sign-in, client permissions and whether the subscription was imported correctly. If the client connects but the destination service denies the request, check the service's message and regional requirements. If the issue occurs only after standby, revisit background permissions and keepalives. These branches help you decide what to check next without needing to learn every protocol term first.

Choose a plan for data; choose a route for the path

Plan data and protocol performance are separate things. A route issue doesn't necessarily mean you need to upgrade your plan. VPNQB monthly plans are ¥9.9/month for 60GB, ¥18/month for 250GB and ¥28/month for 500GB. Data resets monthly on your activation date; mid-cycle upgrades are prorated based on the remaining days. Data add-ons stay available until used and never expire: ¥158/300GB, ¥358/1000GB and ¥658/3000GB. Check the plans page for billing details, then choose based on your own usage rather than a brief speed test.

VPNQB supports Windows / macOS / iOS / Android / Linux, with no device limit. No email address is required to create an account; just choose a username and password. Payment methods are Alipay / WeChat Pay / USDT, and VPNQB offers a 14-day no-questions-asked refund. The point of comparing technical options is to find what works with these stated facts and the configurations currently available—not to chase newer protocol names. If you still can't identify the issue, visit the support page with your network conditions, the stage where the error occurs and the steps you've tried. That can help avoid repeating the same checks.
