AT&T has go phone sims. they are a voice sim that does not work on iPads either. if you insert an AT&T go phone sim in an ipad, it will not even connect to the cell tower. its a useless brick.
and the funny thing is they have this special sold separately AT&T go phone sim that costs $15 that is specifically for the ipad 3 or the original ipad mini 1.
AT&T claims that no other ipad will work with this sim
i asked AT&T several times whats the deal here with this sim?? , why are you charging people $15 for a sim card and only limiting to these two iPads??? , when i can just go into any AT&T store and get a free sim card for any cellular enabled ipad i have ???
they never responded to me. they censored my questions. i got an email back saying i was muted.
i think they are charging you $15 so you can pay cash for your ipad plan
so i would say verizon is the exception here.
