US Plan Text and Data Work, Talk does not

[NewPlan1234]

Im Florida, paid for a talk, text, and data plan, but the talk won't work. Roaming is on, and have restarted the phone.  Last time I traveled to the US, the add-on worked and was great.  This time, I can text and use data, but no talk. I've had this problem before. I need this escalated quickly as I'm obligated to have phone access for work while away, but, I guess the best I can do is post this publicly?

This basically worked. I can use T-Mobile for calls, and AT+T for data.

if the cellphone is not volte enabled by PM, you need to be able to drop to 2G for calling....and only T-Mobile will work. If you have a volte enabled phone, you have access to either T-Mobile or AT&T. Make sure to select 4G in network settings and NOT 5G.

Manually connect to the AT&T or T-Mobile network for your roaming to work in the Cellular Data Option. Also, enable VoLTE.
