iphone text message 15.0.1 update
My Iphone 12 pro won't send text messages that are not imessages. It worked a few days ago. I recently updated to 15.0.1 - not sure if that caused it. I have restarted the phone, I have WI-FI, the SMS tab is on green. I get the message - "not delivered" with the red exclamation point which i have hit and did the "try again" which didn't work. I also cannot receive messages from non IPHONE users. They do not get a message that the message was not received. Imessaging works. I turned messages off and back on, too.
iPhone 12 Pro, iOS 15
