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...
IPv6 seems to be an issue with a number of things, including roaming. What the issue is, I have no idea because using IPv4 is a simple enough solution until whatever the issues are, get resolved.
