After living in an 'Off-Network' area for almost a year, AT&T has just now sent me a letter stating that I've used too much 'off-network' data (using my iPhone 4.) They have given me three options: - Select a new carrier (may be able to keep current number, no early termination fee) - Terminate my service with AT&T, and not pay an early termination fee. - Select a 'roam restriction' feature, which would confine my data to AT&T's network only (which would not be beneficial for me, as most of my data consumption occurs in 'off-network' areas.) I will more than likely choose either the first or second option, but I'm more concerned about what happens after that. Do I have to send back my iPhone? Do I wait for the next iPhone and get it through Verizon? And if I were to wait, does anyone have recommendations for a prepaid phone to use in the meantime?
