Carrier All iPad Air and rMini models are compatible with all major cellular carriers*

[TWO2SEVEN]

I have seen at least three threads about this today.

From a hardware stand point all LTE models are compatible with all carriers.

*Carriers listed on Apple's store: AT&T, Verizon, T-Mobile, Sprint.

**Some have reported issues with the carriers willingness to activate iPads that were not purchased from them.

Yes, they are compatible with all major carriers. Whether they're compatible with "Bubba's Cellular Network" or not is another matter.
