A VPN under ¥10 per month should not be judged by the payment page alone. Whether a budget plan is worth using depends on whether its traffic allowance fits your needs, whether its routes suit your current network, whether the client can import the configuration correctly, and whether its refund terms are clear. VPNKF's monthly plan at ¥9.9 includes 60GB of traffic, access to 120+ countries and 210+ routes, unlimited simultaneous devices, and a 7-day no-questions-asked refund. These are verifiable plan facts, but they cannot replace a connectivity test on your own network.
Here, “testing” does not mean citing a speed screenshot detached from its time, location, and access network. Instead, the budget plan is broken into repeatable checks: whether the subscription imports, whether the protocol completes a handshake, whether websites and target services load, whether DNS exits are consistent, whether sessions remain stable after switching routes, and whether traffic use matches your habits. This is more useful for long-term buying decisions than a single peak-speed result.
What a Plan Under ¥10 Clearly Includes
The first step in evaluating a budget plan is turning “cheap” into specific terms. Price only describes the payment threshold; it does not establish route quality, available regions, or usage limits. For VPNKF's corresponding monthly plan, you can verify the following.
Unlimited simultaneous devices means that one account can be used on multiple devices, not that traffic increases with each additional device. Desktops, tablets, mobile devices, and routers connected at the same time all share the plan's traffic allowance. Estimate your main usage first, then decide whether 60GB is suitable instead of simply counting how many devices you plan to install.
The number of countries and routes answers whether there are selectable exits; it does not mean every route suits every local network. Different carriers, access methods, evening congestion, and wireless quality all affect the result. The same exit may perform differently for different users, so a budget plan especially benefits from testing in your actual environment.
Comparing Direct, Relay, and IEPL Routes
Route structure deserves more attention than node city names. An exit in a particular region only identifies the final outward access location; the path between your network and that exit depends on the route structure. Common structures include direct connections, relay connections, and IEPL lines. None has an absolute ranking outside a specific scenario. The key questions are whether your current network can reach the entry reliably and how the route performs during congestion.
| Route structure | Basic path | Typical characteristics | How to test it |
|---|---|---|---|
| Direct | Local network connects directly to an overseas entry | Simple path; actual performance depends heavily on the local carrier and international exit | Check the handshake, initial page load, and sustained transfer separately |
| Relay | Connect to a relay entry before forwarding to the target exit | The entry may be easier to reach, but relay scheduling and shared load affect performance | Compare different entries in the same region and observe whether switching helps |
| IEPL | Entry and exit are linked through dedicated international transmission resources | The path differs from ordinary public-internet connections and is generally used for more consistent cross-border links | Compare it with ordinary routes on the same device and access network |
IEPL describes a transmission route, not an application-layer protocol, and it does not automatically mean that a particular website will be accessible. A target service may also evaluate the exit IP, region, account status, and request behavior. After seeing “dedicated line,” still check whether the exit region is correct, whether the target page loads fully, and whether the login session remains stable.
How Protocols Affect a Budget Plan
Common subscription protocols or transport options include Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC. They define how the client connects to the server, but the final result also depends on server configuration, transport parameters, route paths, and client implementation. A newer protocol name does not mean it will be faster on every network.
Shadowsocks, VMess, Trojan, and VLESS
Shadowsocks has a relatively straightforward structure and broad client support, making it suitable for common proxy scenarios. VMess and VLESS are often used with different transport methods. Subscription entries must include the server address, authentication details, port, and transport parameters; a missing field or incorrect parsing by an older client can cause connection failure. Trojan commonly uses a TLS connection, so system time, certificate validation, and domain resolution issues may affect the handshake.
You do not need to choose a plan based only on its protocol names. A more reliable approach is to import the complete subscription provided by the service, let the client read the matching configuration, and then compare connectivity among exits in the same region. When copying an individual node manually, transport settings, TLS fields, and the server name are the details most likely to be missed.
Hysteria2 and TUIC
Hysteria2 and TUIC use modern UDP-based transport approaches. On links with packet loss or jitter, they may perform differently from traditional TCP transport. However, some office networks, public networks, and routers restrict UDP. If a handshake fails, do not immediately conclude that the server is offline; first verify with another protocol or entry route.
Client version also matters. Older versions may not recognize newer protocols or may fail to read subscription parameters correctly. If an update produces an “unsupported type” message, update the client core first and fetch the subscription again instead of repeatedly editing the server address.
Subscription Import Across Platforms
A subscription link usually contains access credentials and should be treated as part of your account key. Do not paste it publicly into forums, screenshots, or online conversion pages. The correct process is to copy the subscription address from the user panel and give it directly to a trusted local client. After importing, update the node list before choosing a route.
- Open the user panel and obtain the subscription link for the current plan.
- In the client, choose “Import from URL” or a similar option and paste the complete subscription address.
- Run a subscription update and confirm that node names, regions, and protocol entries appear.
- Choose a nearby route or one with clear entry information for the first connection.
- Open the target website and check the exit region, DNS resolution, and actual loading behavior.
- Record usable routes, then configure global proxying or split tunneling according to your applications.
Windows clients can usually provide a system proxy and TUN mode. A system proxy affects only applications that follow system proxy settings; TUN mode covers more traffic but requires the relevant network permissions. The basic difference is similar on macOS, where enabling a network extension for the first time may also require approval in System Settings.
iOS and Android clients are more affected by system background policies. After changing networks, entering a power-saving state, or remaining idle for a long time, the system may reclaim the connection. Reopen the client to confirm tunnel status. Linux commonly offers both graphical clients and command-line cores; the important checks are whether the configuration directory, core version, and system proxy environment variables match.
Importing on a router is not the same as importing on a desktop. The router firmware must support the relevant protocol and subscription format, while hardware capacity also affects encryption and forwarding. If only a few devices need occasional access, connecting them individually is easier to troubleshoot. Router-side subscription management is more worthwhile when unified split tunneling is needed or when devices such as TVs cannot conveniently install a client.
How to Run a Repeatable Connectivity Test
Testing a low-cost route should begin with whether it works, then examine whether it suits a specific task. Before testing, close other proxy tools and bandwidth-heavy downloads. Keep the same device, local network, and target service throughout. This makes it more likely that changes after switching routes come from the route itself.
- ✅ The client updates the subscription successfully, with complete node region and protocol fields.
- ✅ After connecting, the exit region matches the selected node and the target website loads fully.
- ✅ DNS requests do not continue through a local resolver path inconsistent with the intended route.
- ✅ After switching routes, a new connection is established rather than incorrectly reusing the old one.
- ✅ Common applications follow the configured global proxy or split-tunneling rules.
- ✅ Actual traffic use matches your browsing, transfer, and streaming habits.
- ❌ Do not use one peak-speed result as a substitute for sustained availability.
- ❌ Do not compare route conclusions directly across different devices or wireless networks.
How to Check for DNS Leaks
A DNS leak occurs when application traffic uses the proxy but domain queries still leave through an unexpected local resolution path. First record the resolver path while disconnected, then connect to a route in a specified region and observe whether the resolver region and exit change with the configuration. If the client offers “remote DNS,” “resolve through proxy,” or a similar setting, confirm that it is enabled and that another network tool is not overriding it.
The resolver region does not always exactly match the exit city. Some public resolvers use proximity-based routing, so the key question is whether queries still expose an inappropriate local path, not whether the city name matches character for character. A browser's encrypted DNS setting may also bypass client rules and should be checked during troubleshooting.
How to Verify Split-Tunneling Rules
The goal of split tunneling is to send applications that need international routes through the proxy while keeping local services direct. Rules generally match domains, IP addresses, application processes, or rule sets. After configuration, open one service expected to use a direct connection and another expected to use the proxy, then check the matching results in the client's connection log.
If an application uses multiple domains, adding only its primary domain may not be enough. Login, images, APIs, and downloads may use different domains. If the page framework loads but its content does not, look in the client log for unmatched requests and add rules instead of permanently switching all traffic to global mode.
Common Limits of Low-Cost Plans
The main trade-off in a low-cost monthly plan is usually traffic. Text chats, web pages, and browsing code repositories are relatively manageable, while operating-system images, cloud backups, and high-bitrate video can consume the allowance quickly. Client statistics help reveal trends, but final billing should be checked against the user panel because services may count upstream, downstream, protocol overhead, and retransmissions differently.
Unlimited simultaneous devices solves a connection limit; it does not mean that every device should stay behind a global proxy indefinitely. Background sync, app updates, and automatic media playback continue transferring data without active user input. A safer approach is to configure split tunneling by device or enable the connection only when needed.
Refund terms reduce the cost of initial verification. The corresponding VPNKF plan provides a 7-day no-questions-asked refund. After activation, test the most important networks, devices, and target services first rather than checking one website and assuming every scenario works. If the result does not meet your needs, contact support within the stated term.

|---|---|---|
| Price and traffic | ¥9.9 / 60GB | Calculate traffic against your main usage first |
| Regions and routes | 120+ countries / 210+ routes | Provides room to switch, but actual performance still needs local testing |
| Simultaneous connections | Unlimited devices | Multiple devices share the plan traffic, so background transfers should be controlled |
| Refund terms | 7-day no-questions-asked refund | Complete key device and route tests within the term |
| Registration requirement | No email address required | Start with a username and password |
Final Buying Checklist for Plans Under ¥10
Before buying, do not begin by asking which provider is fastest. Define your pass criteria first. Your usual devices, target regions, router needs, monthly transfer types, and willingness to switch routes matter more than a public speed-test image.
- ✅ Price, traffic, billing period, and refund terms can be verified directly on the plan page.
- ✅ The registration process needs no email address, and account credentials can be stored securely.
- ✅ The subscription supports the current platform client and fully imports the required protocols.
- ✅ The node directory identifies regions and route types instead of using vague names.
- ✅ Direct, relay, or IEPL paths are available for comparison in the actual environment.
- ✅ The client supports remote DNS, split-tunneling rules, and TUN mode where needed.
- ✅ Key scenarios can be tested within the refund period after activation.
- ❌ Do not treat route count, protocol count, or one speed test as a stability guarantee.
Overall, VPNKF's ¥9.9 / 60GB monthly plan suits users with a defined budget, manageable traffic needs, and a willingness to select routes from the directory. Access to 120+ countries and 210+ routes provides a broad range of exit choices, unlimited simultaneous devices make use across platforms easier, and the 7-day no-questions-asked refund leaves time for practical verification.
It should not be understood as an unlimited-traffic plan or as a promise of identical performance on every network. The sensible way to use a budget plan is to import the subscription, verify protocol compatibility, exit region, DNS, and split tunneling, then decide which devices and applications need long-term access.
