Does the subscription refresh?
If the server list does not refresh, the issue can be before the VPN server: the network blocks the subscription URL, the app cannot open it or the profile is old.
On Tele2/T2 issues often look like timeout, endless connection or no internet after the connected status. Start with profile refresh and network comparison.

VPN works at home but not through the SIM card
the client connects but pages do not open
only switching network or LTE/5G mode helps
the error repeats after phone restart
Refresh the WersidePN subscription in your client.
Try the second profile if the app shows it.
Turn off Private DNS and other VPNs, then reconnect.
If the server list does not refresh, the issue can be before the VPN server: the network blocks the subscription URL, the app cannot open it or the profile is old.
That is a different case: the tunnel may be up while DNS, route or a specific ISP still interferes with traffic. Test a website, Telegram and YouTube separately.
Immediate timeout, TLS error or import marks often point to the app, network or blocked profile refresh method rather than the plan itself.
Split the issue into two steps: whether the subscription refreshes and whether VPN connects.
If the subscription does not refresh, check link access, network, device date and app version.
If VPN connects but sites do not open, check DNS, another network and specific services separately.
If the issue happens only on mobile data, filtering can be on the operator side, not in the app.
If Wi-Fi works, keep the working profile and contact support with the mobile operator name.
Do not delete the account or payment: usually the profile or connection method needs updating.
