Hi everyone - I apologize if this has been asked before but I wasn't able to find anything relevant. I'm trying to use my Voice sim card with unlimited data in my iPad. I feel like there must be a way, but every time I transfer the sim card, the iPad goes from AT&T service to no sim card within a matter of seconds. Has anyone had success in doing this? Thanks in advance! ---------- I believe it may do with IMEI numbers not matching, but I've heard some people have been able to do this successfully.
