I think the OP means will the iPad Pro work only with the Apple SIM. And I think the answer is, at this point, nobody can say for sure. I think activation questions will be resolved closer to launch.

My Mini 4 came with an Apple sim. Before I turned it on for the first time, I replaced it with an ATT sim from an iPad Air 1 and it went straight to LTE instantly. Yeah, it should work but no one will know for sure till release.
