Well just bought my third mini , this time for my wife. Question she has a Ipad2 16gb with AT&T monthly 14.95 service . Now I'm going to sell the Ipad2 do I try and cancel that service or should I switch SIM cards and put her IPad 2 card in the Mini. Her service for her phone and such is on a different account than mine so not putting it on my share plan. I'm not even sure how to cancel the auto monthly 14.95 charge on her IPad 2 which I actually would like to do since I would like the charges to be on a different business credit card instead. Need advice , thanks.
