those are two seperate things. Sure AT&T can unluck the phone for use on another carrier but that doesnt necessarily mean it can be used on XM or other CDMA carriers. The phone itself is the problem in that regard. It comes down to the bands its able to receive and the model of Iphone 7(+) Att chose to go with wont work with the bands Verizon/XM uses
Hi tomkathey99, the information that (elie2wins) shared is correct. I also checked our compatibility list and I show that the IPhone 7 and 7 Plus are not compatible with the network so it will not be eligible to be transferred over.
