New ATT prepaid account (Port in) calling working. data working, sms not working
Just ported my number in to ATT Prepaid on the $50 ($40 with autopay) plan.
Calling is working, data is working but SMS is not working
this is on an unlocked ATT branded Iphone XR
when I go in to settings / Messaging and choose iMessage it says activation unsuccessful.
What do I need to do or how can i get this fixed so I can use SMS?
