Android 13 with VPN on causes calls to go to voicmail
It appears that T-Mobile has an issue with Android13 devices when using a active VPN connection. You cant call out or receive phone calls (auto voicemail). Some believe that the APN Ipv6 is the issue...
The thing is with VPN's, is they redirect traffic. Certain things are not reliably redirect able, like a phone call. Especially if the VPN is doing it's job at hiding your original location. You might have better luck troubleshooting it with NordVPN. There are different types of VPN types. The higher the security, the less likely it will transfer your calls though because VoLTE uses data, which your VPN is altering the traffic on, to connect your calls.
