VPNBeginnerFAQ: Multiple Devices, Data Usage, and Speed Limits

Monthly plans or data packs: which should you choose?

If you access international websites regularly, a monthly plan may be a good fit. If your usage is occasional, or you only connect while traveling or researching, compare data packs. Monthly plans reset each month; data packs last until used and never expire. Don't compare prices alone—consider how consistently you'll use the service and whether you mostly browse text or stream video.

If you're not sure how much data you use, start by checking your devices' app data usage, then compare it with the usage shown in your account dashboard. Video quality, cloud backups, system updates and file downloads often use far more data than text pages. “Daily use” can mean very different things: reading documents and streaming video continuously aren't comparable. See the plans page for details.

What does using a VPN on multiple devices mean?

VPNSize has no device limit, so you can set it up on different devices without treating each new computer as an additional plan. But no device limit doesn't mean each device gets its own data allowance, or that simultaneous downloads won't affect one another. Check the plan and usage shown in your dashboard. Adding the same subscription to more devices doesn't add data.

Devices connected at the same time may share your home broadband, Wi-Fi and the resources of the selected route. For example, if one computer is syncing files, video may buffer on another device because your local connection is busy—not because of an account limit. Pause high-data tasks on other devices and check whether the same video improves.

Your subscription link lets a client retrieve your connection configuration, so protect it like a password. Don't post it in public forums or send screenshots containing the full link, QR code or account details to strangers. If you need help, share the error message with sensitive details removed and mention which client you're using.

How is data measured, and when does it reset?

Data on monthly plans resets each month on your activation date, not at the start of the calendar month. Check your account history in the dashboard for the next reset date; don't rely on your device's calendar around date boundaries. If you upgrade mid-cycle, the price difference is prorated for the remaining days. Check the dashboard confirmation for the exact amount and when the change takes effect.

Your client's local usage counter, your operating system's network stats and the usage shown in the service dashboard may cover different things. System stats may include traffic that doesn't go through the proxy, while a client may show only the current session. Check the service dashboard for your remaining plan data. If the site doesn't specify how uploads, downloads or different routes are measured, ask support rather than assuming another service's rules apply.

When you disconnect the proxy, business data normally stops traveling over that proxy connection, but your device may still use the local network. Conversely, staying connected doesn't necessarily use a lot of data; usage depends on what your apps send and receive. Check background video, automatic updates and cloud sync.

Does a slow connection mean your speed is being limited?

A slower connection alone doesn't prove that your speed is being limited. Performance depends on your local network, destination website, exit region, route congestion, device and client settings. We don't have verifiable information on a fixed bandwidth cap, so “no device limit” shouldn't be taken to mean unlimited speed or a guaranteed speed.

A direct connection generally means the client connects straight to an overseas server; a relayed connection passes through an intermediate node before reaching its exit. IEPL usually refers to an international Ethernet private line—the underlying transport link, not a guarantee that the entire path from your browser to a destination website uses a dedicated line. A route label alone can't predict your experience; test it on your own network and the sites you use. VPNSize covers 90+ countries and 150+ routes, but coverage doesn't mean every destination will perform the same way.

1. Pause downloads, syncs and video on other devices, and make sure your local network isn't saturated.
2. Try different websites to see whether one site is having trouble or all requests are slow.
3. Switch routes on the same network while testing the same content, and avoid changing too many variables at once.
4. Try another available local network. If the issue only occurs on one network, start by checking that network.
5. Note when it happened, the exit region, any client error and the steps to reproduce it, then contact support through the dashboard.

Avoid repeatedly downloading large files to “test stability”—it uses data and may not reflect your actual use. If web pages load smoothly but video stutters, consider the platform's content delivery nodes, account region and playback quality. A change in exit IP doesn't guarantee that a platform will allow playback. See the streaming guide for more context.

After importing a configuration, how can you confirm the connection is working?

A subscription link gives your client the route configuration provided by the service; opening it in a browser doesn't connect you. Supported subscription formats and protocols vary by platform and client. Shadowsocks, VMess, Trojan, VLESS, Hysteria2 and TUIC aren't interchangeable just because they're all proxy protocols. Choose a compatible client based on the dashboard instructions; this article doesn't claim VPNSize supports every protocol listed here.

Windows and macOS clients commonly use either system proxy settings or a virtual network adapter, and each method may cover different apps. iOS and Android generally require system permission for a VPN connection, but similar permission names don't mean their routing rules or implementation are the same. If you can't find a setting, follow the guide for your platform in Guides.

• ✅ Find the client instructions for your platform in the dashboard, and check the download source and configuration requirements.
• ✅ Import the link from the client's subscription menu and refresh it. Check that the route list loads without errors.
• ✅ Choose a route, connect, and grant the network permissions requested by your system.
• ✅ Check your exit using IP check, then visit a site you actually need to use.
• ✅ If only some apps aren't working, check whether they follow the system proxy and whether the split-tunneling rules match.

A client showing “Connected” only confirms that a connection state is active; it doesn't prove that a specific app is routed as intended. With split tunneling enabled, a check site may use a direct connection, so seeing your local exit doesn't immediately mean the VPN has failed. First check which rule handles the test request, then interpret the result.

Does the VPN need to stay on? How do you check split tunneling and DNS?

Whether to keep the VPN on depends on how you use it. If you only need it for particular international websites, connect when needed. If you want certain apps to keep following the configured rules, leave the client running. The connection may change after sleep, a network switch or closing the client. Check it again before anything important instead of relying on the status icon as a lasting guarantee.

Rule-based routing uses conditions such as domains, addresses or apps to decide whether traffic connects directly or through a proxy; the exact options depend on the client. Global mode generally routes requests handled by the client through the selected proxy, but that doesn't mean it covers all traffic on your device. Don't stack proxy apps while troubleshooting: running multiple traffic-capture methods at once makes routing harder to understand.

DNS translates domain names into addresses. A DNS leak occurs when a lookup that should follow an expected route takes a different one. A website loading doesn't prove that DNS requests are routed correctly, and seeing an unfamiliar provider in a DNS test doesn't automatically mean there's a leak: a remote DNS resolver may differ from the provider handling your connection. Check the client's DNS, encrypted DNS and routing settings together instead of relying only on the country shown on a test page.

What else should you check before getting started?

VPNSize doesn't require an email address; you can create an account with a username and password. Keep your credentials safe and check the recovery options in the dashboard before using the service. Not requiring an email address reduces the information you provide, but network activity may still be linked to your identity. Account sign-ins, payments and records kept by destination websites are separate data-handling matters.

Payments are accepted via Alipay, WeChat Pay and USDT. Choose a method that suits you and verify the payment details; a payment method's name doesn't guarantee anonymity. Before deciding whether a plan is right for you, test it with your usual network, devices and apps.

VPNSize offers a 14-day no-questions-asked refund. Under the stated policy, you can request a full refund within 14 days of your first payment; this isn't a trial period that can be repeated indefinitely. For billing, connection or refund help, submit the details through support in the dashboard, and don't expose your full subscription credentials in attachments.
