Critical part to US roaming depends on T-Mobile/AT&T coverage and whether you can connect successfully onto either network.

If the phone is not connecting to T-Mobile/AT&T, change the Network Connection from Automatic to Manual and select and test both T-Mobile and AT&T and see which one you can connect.

If your issue is with data, make sure your Roaming Mobile data is enabled and you have disabled your mobile data limiter.  Also change your network mode to 4G (and don't try 5G until you can connect and works on 4G)

If your issue is with voice, make sure VoLTE is enabled on the device setting.  And if it does not work, try to change the Network to T-Mobile ONLY, and change  Preferred Network Type or Network Mode to 2G and see if the calls go through.
Also, you can download VoIP app TextNow as a workaround to make calls and text if you have Wifi or if your roaming has data component and data  is working

@Fdrcamb and you confirmed that the add on was successfully added to the account?

Is your phone is VoLTE enabled? Put your phone to 4G/LTE and connect to T-Mobile or AT&T. 

Turn off 5g or auto connect if you have it on.

If calls still don't work, put your phone to 2G and connect to T-Mobile. From the settings menu, turn on data roaming.

Restarting phone might help.
