I just bought my daughter-in-law an unlocked Moto G Power to use with her AT&T Sim. She is having issues with text and calls. When she sends me a text, it goes through immediately. When she tries to text someone else, it says waiting for connection, and then takes up to an hour to send the text. She can't make any phone calls at all. She can't receive any phone calls at all. She can get on the internet though. Her APN settings are exactly the same as mine. Any ideas on what is going on and how to fix this? Any help would be greatly appreciated. Thank you.
