T2 is a mobile operator, and that's its main difference from the rest on our list: it has no home internet under its own brand. This means that all VPN questions for T2 subscribers relate to the mobile network, and they're easier to break down — there's only one scenario.
Short answer
If the VPN won't connect, change the location in the app. If it drops while you're moving, that's switching between base stations, and the connection usually recovers once you stop.
Why "mobile network only" makes the task simpler
For subscribers of operators with home internet, half the problems come down to the router: filtering, custom DNS, a second VPN on the router itself. Here that layer is absent. Only the properties of the cellular network remain:
- Shared external address. Subscribers reach the outside through the operator's gateway.
- Smaller packet size. The MTU is lower than on a wired connection, and some connections get fragmented because of this.
- Mobility. Moving between towers changes the route and breaks the session.
- Regions. Conditions differ across parts of the country even within one network.
If you connect other devices to your phone
Without home internet, a common scenario is tethering from the phone to a laptop or tablet. There's a nuance here: the VPN can be turned on either on the phone itself or on the device that connected to it, and these aren't the same thing.
- VPN on the phone sharing the internet. Depending on the system, the tunnel may not extend to the connected devices — they'll go online directly.
- VPN on the laptop connected to the hotspot. This works more predictably: the tunnel comes up on the device itself.
If you need tethering regularly, it's more reliable to install the app on each device — one VolnaLink subscription covers up to three at once.
What to try, in order
- Change the location in the app. The most effective action: if a specific server doesn't get through the operator's network, a neighboring one usually does.
- Check the internet without the VPN. Open any site with the VPN turned off. If it doesn't open either, the VPN isn't the issue: you've run out of plan data, there's no signal, or there's a problem on the network side.
- Check the list of VPN profiles in your device settings. A leftover configuration from another service in the system intercepts traffic and looks like a failure of the current app.
- Reconnect instead of waiting. The client may hold a dead connection, thinking it's alive.
- Remove battery-saving and data-saving restrictions for the app — especially on Android.
- Restart the device if the routes are "stuck."
About VolnaLink
Test it on your device
8 hours free, no card required. Full access to all servers.
There are apps for Windows, macOS, Linux, Android, iOS, TVs, and browsers. The operator makes no difference to the service — there's no tie to a specific SIM card. The first 8 hours are free, no card needed, so you can test it on your own connection in advance.
Why there are no percentages and charts here
You won't find in this article a number of checks, a success rate, or an average connection time. The reason is simple: we haven't measured them yet, and we won't make up such figures — neither about our own service nor about others.
We're preparing our own monitoring separately: exactly how we'll count is described on the page "How we test VPN performance in Russia". Once enough measurements accumulate, the results will appear in the monitoring and in this article in place of this paragraph.
If nothing helped
Write to support — no registration is needed for that. To keep the investigation from dragging on, state right away the operator, city, connection type (mobile or home), app version, and chosen location. With this data the issue is resolved in minutes instead of hours.
