So I purchased a T-Mobile iPad Air which is coming on Monday. I planned on the most part to take advantage of the free 200mb. We may eventually go to a share everything plan on Verizon. From what I am reading it seems much easier to have a Verizon iPad Air and insert a T-Mobile sim than vice versa. Anyone with a good/easy experience swapping a Verizon sim in a T-Mobile iPad? The few posts I have read so far seem like you really need to swap and finagle things to get a T-Mobile iPad Air to work on Verizon. Thanks.
