Besides tmobile and att, which are the other providers that provide decent/ok coverage in the US? I have an unlocked iPhone and just trying to see what are the cheapest options available..
There are some smaller ones out there such as Simple Mobile, etc. If you look for them you can find them, but bear in mind, they all probably will use AT&T or T-Mobile coverage anyway. The US as a whole really only has a few key players in the wireless phone industry, and those are, AT&T, VZW, Sprint & T-Mobile. 2 CDMA and 2 GSM
