Problems with network compatibility.

Hi all,

I got a text from 28891323 saying:

"Welcome, you are roaming on AT&T. Due to network technology compatibility, traditional voice calls will not work.   Please use data, SMS, and app-based calling."

I checked already the recommendations for this problems from earlier posts but I cannot fix the problem. I have an iPhone13 Pro and the VoLTE is on.  What should I do now that I can normally phone?

Thanks for a fast response!

It's not a phone issue, but it is an issue with whichever service provider you are using to roam in the United States.   'Free'  and 'Global'  do not work well with VoLTE.
