Try changing your phone to 4G or LTE. Supposedly that will work better with AT&T. 5G will work with T-Mobile.

HI @RayParker 

try connect to T-Mobile first.  change the network mode to Automatic and test again the voice calls

if still not working, connect to T-Mobile but change  the network mode to 2G and test once more time

@RayParker 

click this for some info on volte, scroll to bottom to see if yours is on the "whitelist".

Did you turn Data Roaming to “On”?

Hey @RayParker 

Go into your network settings, turn off automatic and choose T-Mobile. Then make sure your your Cellular Data is on and your roaming is on then reboot.

@RayParker 

make sure Roaming Data is enabled for data to work.

Restart phone. Try selecting either of T-Mobile or AT&T.

Is you phone on PM's volte whitelist ? If not you need to manually select 2G for calling and only T-Mobile....but service will be poor, at best.
