No cell service
I have had a Samsung Galaxy S22 since May 2022. Two days ago, I couldn't make calls-- they wouldn't connect. Twice, calls connected but the person I was calling could not hear me, though I could hear them. Nothing I entered on the key pad, when using automated call attendants, worked. Oddly enough, my Samsung Galaxy S20, with a different phone number but on the same AT&T account, is working fine. Any advice?
