I ve noticed that the new LTE iPhone 5 Data plan is not working on other devices. I used a micro SIM adapter and went back with my 4S and it is working perfectly, but DATA will not work on my HTC ONE X or on my Unlocked International Version Galaxy Note. I had the Unlimited LTE 4G for smartphones with my One X and data always has been working on all the phones including my iPhone, this is acutally the first time that I see that data is working only for a specific phone! I tend to swap phones a lot, and I ve noticed this problem....anyone have the same issue?
