Using WiFi calling with Pixel 7
I have a Google Pixel 7 model number GVU6C. I have been using an MVNO (Red Pocket mobile) on their GSMA (AT&T) system. I can not activate WiFi calling and can not use unconditional call forwarding. WiFi calling button just replies "unable to activate. Try later". When trying unconditional call forwarding I get the message "Generic Failure". Red Pocket has no answer. I would switch to AT&T but I want to be sure if these features will work with their service. The AT&T stores have no answer. I am particularly interested in the prepaid one year service from AT&T.
