Text Message from AT&T to Replace SIM
Would you trust a message that says "Hi, It's AT&T. This is a courtesy notice to replace your SIM card before our 3G Voice Network shuts down in February 2022" and it provides a link asking for personal information to get a SIM. It says "Your AT&T Prepaid phone will STOP WORKING". (I did NOT click on the link)
Does AT&T really send text messages like that?
My current phone is Motorola G7 Play and supports LTE.
Is there any reason that a new SIM be required, when the phone is 4G compliant?
