Just stopped receiving SMS on iPhone with iOS 18.5 the past few days. Tried force restarting phone, resetting network settings etc. to no avail. RCS is also not activating. Can send SMS just not receive. Started a support chat with AT&T. They reset something on their end and I lost cellular connection for a few seconds and the SMS I hadn’t received all flooded in. Can now received SMS but RCS will not activate. AT&T claims that RCS can take 24 to 48 hours to activate after reset. We will see. I can at least get my 2FA texts etc again. Anyone else?
