No phone calls and no text messages.

I bought a new Galaxy S7 FE last month.  I used Smart Switch to send everything from my Note 9 to the tablet.  Everything went smooth.  I was able to text and use the phone on both devices. Perfect for two weeks.  Then I bought a S22 Ultra and used Smart Switch to send everything from the Note 9 to the S22 Ultra. Everything went well except that the tablet no longer receives text and the phone doesn't work. Everything works fine on the S22 Ultra. After a week I  reset the tablet to factory condition and used Smart Switch to send it everything from the S22.  I went well but still no phone or text on the tablet.  I did notice on Smart Switch set up that when I clicked on Android, my only choice was Rick's Note 9 which is on it's way to Samsung.  Please help.  You people know way more than I do about these things.  An AT&T employee checked both devices and said my settings were correct.   Thanks in advance for your help.
