Good Morning @Coaltinkey,


Let's work together to get this resolved for you.


If you are bringing the phone over from a different carrier to AT&T, make sure the device is unlocked as it seems it may still be tethered to the previous carrier. 


Should you find AT&T was the previous carrier, submit an unlock request to make sure the device is unlocked and ready for your new carrier.


Were you able to use the device prior to inserting the new sim card?  


Let us know by following the instructions above if you still need assistance.
