How should you choose a VPN in 2026? Compare services for cross-border access by starting with your network and the apps you need, then weigh the price. Low latency doesn’t guarantee fast downloads, and a high speed-test result doesn’t guarantee stable calls. The right choice depends on whether you’re a student, AI user, streamer or part of a multi-device household.
Sources and testing limits: This article is published by VPN15 and is not an independent third-party ranking. We don’t have publicly verifiable, like-for-like test results for all five services, so we won’t report speed scores or declare a winner. Below, we list the services under consideration, VPN15 plan details we’ve confirmed, and a practical method for comparing them yourself. Items awaiting verification should not be treated as drawbacks.
What to verify when comparing five VPN services
This article compares VPN15, Proton VPN, Mullvad, NordVPN and Surfshark using the same verification checklist. Their inclusion doesn’t mean they offer the same type of product or that they’ll all connect on your network. Terms, app features and payment pages can change, so descriptions from older reviews shouldn’t be treated as current facts.
First rule out options that don’t fit: check whether there’s a compatible app for your device, whether the service connects on your network, whether your target app allows the access method, and whether your budget covers your needs. Once those boxes are checked, comparing speed and support is often more useful than relying on a leaderboard.
| Service | Information confirmed for this article | What to verify before comparing |
|---|---|---|
| VPN15 | Monthly plans, data packages, supported platforms and refund terms are covered below | Test speed, stability and target apps on your own network |
| Proton VPN | No current plan details or like-for-like test records available | Check each provider’s current plans, apps, terms of use and refund conditions |
| Mullvad | No current plan details or like-for-like test records available | Check each provider’s current plans, apps, terms of use and refund conditions |
| NordVPN | No current plan details or like-for-like test records available | Check each provider’s current plans, apps, terms of use and refund conditions |
| Surfshark | No current plan details or like-for-like test records available | Check each provider’s current plans, apps, terms of use and refund conditions |
This table clarifies what the evidence does and doesn’t show; missing information isn’t a hint that one service is worse. Without test results, the fair conclusion is “needs verification,” not “slow,” “unstable” or “unavailable.”
How to test speed and peak-hour stability
Control your test conditions as much as possible. Use the same device, network, destination region and testing tool; pause background downloads, system updates and cloud sync. Different services may use different routes. The same exit-region label doesn’t mean the same data center, carrier or return path.
- Check your baseline first. Disconnect from the service and see whether your local connection is already fluctuating. If it is, it’s hard to attribute later results to the service.
- Keep the test targets consistent. Use the same speed-test server where possible, and test everyday websites, file transfers and the apps you actually use. Don’t keep only the best-looking result.
- Test when you actually use it. Repeat the same checks at ordinary times and during peak hours. Note failed connections, dropouts, buffering and reconnections.
- Record all the conditions. Note the date, internet provider, app version, connection method, exit region and routing mode so you can repeat the test.
- Test real tasks. For video calls, check whether audio and video stay smooth; for file transfers, watch sustained throughput; for web apps, see whether you can complete the task.
What latency, jitter, packet loss and throughput tell you
Latency is the round-trip wait time; jitter measures how much latency varies; packet loss means data may need retransmission or may not arrive in time. Throughput is the rate of sustained data transfer. Calls and remote desktops are more sensitive to jitter and packet loss, while large file transfers depend more on sustained throughput. The latency shown in a connection interface may only reflect a probe to one node, not the full route to the app’s server.
Some networks deprioritize or limit ICMP probes, so a ping with no reply doesn’t prove a route is down. Test real apps too, and don’t treat a speed-test app’s automatically selected nearby server as a measure of access to every international website.
How to assess routes and protocols
IEPL, relay and direct connections describe different ways a route can be arranged. IEPL usually refers to an Ethernet private line provided by a carrier, but a product label alone can’t prove that the entire route uses a private line. A relay typically routes traffic through an entry point before it reaches the exit; this may improve one part of the route, but it can also add overhead. A direct connection typically avoids a separate relay entry point operated by the provider, but still travels over public carrier networks.
So neither “a private line is always faster” nor “a direct connection always means lower latency” is a reliable conclusion. Check the route details and test on your own network. VPN15’s confirmed coverage is 90+ countries and 240+ routes. Coverage figures don’t mean every route suits every app, and they don’t guarantee streaming access.
Protocols and routes are different things. Shadowsocks, VMess, Trojan, VLESS, Hysteria2 and TUIC differ in how they connect, what transport they rely on and which clients support them. A protocol name alone tells you nothing about carrier routing or the reputation of an exit IP. We don’t have a confirmed list of VPN15’s supported protocols, so we make no claims about specific protocol availability.
Subscription links often contain access credentials, so treat them like account passwords. Import them only into trusted apps; don’t post them on public forums or paste them into unknown online conversion tools. Being able to import a subscription doesn’t mean an app supports every node or configuration option it contains.
How to verify streaming and AI apps
Streaming access isn’t permanent. Apps may assess access using the exit IP, account region, content licensing, device settings and risk controls. Opening the home page doesn’t mean the show you want will play; a successful playback once doesn’t guarantee access from other regions or accounts, or at a later time.
- ✅ Use the device and account you plan to keep using. Check whether the target content actually plays, not just whether you can reach the sign-in page.
- ✅ During playback, test seeking, changing video quality and continuous viewing. Note any error messages when playback stops.
- ✅ For AI apps, test sign-in, chat, file uploads and any other features you need. Reaching the home page isn’t a substitute for completing the full task.
- ✅ Check the app’s regional requirements and terms of use. A working connection doesn’t mean your account is eligible to use the service.
- ❌ Don’t treat a logged-out landing page, cached page or one successful screenshot as a guarantee of continued access.
AI users should also distinguish network problems from app restrictions. Account permissions, busy servers, payment status and regional policies can all trigger errors. Save the error details, then compare what happens before and after switching exit regions. Avoid repeatedly changing your account region, and don’t mistake a risk-control flag caused by a shared exit IP for a failed app installation.
How to compare prices and refund policies
Compare like with like: is the service billed monthly or by data usage? Does it require a long-term prepayment? Can renewal prices change? Which orders are eligible for a refund? We don’t have current, verifiable prices for the other services, so this article doesn’t quote figures from promotions or older articles. Here are the VPN15 plan details we’ve confirmed.
| Billing type | Price and data | Data terms |
|---|---|---|
| Monthly plan | ¥9.9/month, 60GB | Resets monthly on the activation date |
| Monthly plan | ¥18/month, 250GB | Resets monthly on the activation date |
| Monthly plan | ¥28/month, 500GB | Resets monthly on the activation date |
| Data package | ¥158，300GB | Valid until used; never expires |
| Data package | ¥358，1000GB | Valid until used; never expires |
| Data package | ¥658，3000GB | Valid until used; never expires |
When you upgrade a VPN15 monthly plan mid-cycle, the price difference is converted into the remaining days. Monthly data resets on the activation date, not automatically at the start of each calendar month. Data packages remain valid until used and never expire. The right billing option depends on your usage: choose based on how much data you actually need and how often you use the service.
VPN15 accepts Alipay, WeChat Pay and USDT. Refund terms: you can request a full, no-questions-asked refund within 7 days of your first payment. This doesn’t mean every renewal payment is automatically covered. To check the policy or contact support, use the relevant channel on the contact page. We don’t have data on support response times, so we make no promises about how quickly you’ll hear back.
Recommendations by use case
Students: Start with your budget and data needs
If you mainly use the service for research, course websites and light collaboration, estimate your monthly data use before choosing a larger plan. VPN15’s ¥9.9/month plan includes 60GB and can be a starting point for budgeting, but whether it’s enough depends on your video, download and update habits. If you use the service occasionally but intensively, compare the total cost of data packages that never expire too.
AI users: Test your full workflow first
Check app eligibility first, then test the features you need and connection stability; speed-test peaks come last. If you upload files, follow your organization’s data policies. Don’t choose any service based only on an “AI supported” claim. Complete your usual tasks with your own account before deciding whether to keep it.
Streamers: Test the content you want to watch
Focus on uninterrupted playback during peak hours, the target region and your data budget. Don’t infer viewing quality from the number of countries covered. VPN15 offers several data tiers, but this article has no verifiable, platform-by-platform playback results, so we can’t guarantee access to any specific platform.
Households with multiple devices: Separate device count from data capacity
VPN15 allows unlimited simultaneous devices and supports Windows, macOS, iOS, Android and Linux. Unlimited devices doesn’t mean unlimited data or unchanged speeds when all devices are transferring data at once. Multi-device use is still subject to your plan’s data allowance, local bandwidth and route conditions. Platform support also doesn’t mean every feature is identical.
Bottom line: If you have a clear budget, want to choose between monthly billing and data packages, and need multiple devices online at once, consider adding VPN15 to your hands-on comparison. If you depend on a particular streaming or AI app, test the task you need first. There isn’t enough evidence here to rank the five services by performance, so don’t treat this article as proof that one is best across the board.
Privacy, split tunneling, and client checks
VPN15 describes its privacy policy as “anonymous, no logs.” You can create an account without an email address and use a username and password. A no-logs policy is a statement about the service’s practices, not a guarantee against every network risk. We also have no independent audit materials to support additional claims. Website sign-ins, browser identifiers and information users choose to submit may still be linked to an individual.
A DNS leak occurs when domain lookup requests that should follow the expected connection route instead take another, unintended path. Check system DNS, client routing rules and your browser’s encrypted DNS settings together. An unfamiliar DNS resolver shown by a test page doesn’t prove a leak on its own; check whether it matches your configuration. Resolving local domains through the local network may also be part of the routing design.
System proxies, app-specific proxies and TUN mode cover different types of traffic. Some apps don’t follow the system proxy. If a browser works but another app doesn’t, first check whether its traffic is reaching the client. TUN mode usually needs additional network permissions and may conflict with other network software; enabling it isn’t a universal fix.
Desktop and mobile operating systems handle background activity, network extensions and permissions differently. Get apps through the official channel for your platform or a download link provided by the service, and grant only the permissions described in the instructions. After importing a subscription, check its update status and any errors. If something goes wrong, first verify the subscription is valid, the device time is correct and the client is compatible; then check the rules and routes.
Keep a short record of your usual devices, target apps, exit regions that work, error messages, data use and refund deadlines. Check these details against the plans page. That gives you a VPN recommendation you can actually use to make a decision—not just a brand name or a one-off speed-test screenshot.
