A:AnswerNo, this particular model only works with AT& T. They make others that work with Verizon & I believe Sprint - it will say the compatible cellular carrier in the description of each IPad.
A:AnswerI bought a new WiFi/Cellular AT&T iPAD at Best Buy to replace an older model, and while at Best Buy had them remove the old one from my AT&T account and replace it with the new one. No change in AT&T charges. I kept the old somewhat fading iPAD and use it just via WiFi now.
