We've been with AT&T for quite a while but lately I've been thinking about switching to Sprint to save money. I would consider T-Mobile but I don't think they have much of a presence around here and since I drive an hour each way to and from work (mostly rural) I would need some coverage in case of an emergency - from what I understand T-Mobile service is virtually non-existant when there are large gaps like that. Other than that I have access to wifi most of the time. I would even consider Verizon if they offered a better plan for the same money or a comparable plan for less but they seem to be on the high side most of the time. Anyway... I just bought an iPhone 6 Plus from AT&T. I bought it on Next but paid it off after one payment. I have not had it unlocked but I would imagine I'd need to do that before doing anything else. I'm a little confused by how these phones are set up now, what are my carrier options with this particular phone? Once it's unlocked could I take it to Sprint, T-Mobile, or Verizon?
