I'm a complete phone n00b, but I'm sure that someone here will be able to give me an answer. We're seriously considering changing carriers from Metro PCS. The network coverage is pretty terrible in our area, and the customer service is beyond gawd-awful. The question is- will our Samsung Code i220 phones work on any other network? This site says that the phone works CDMA 1900, but this site says that it works on CDMA 1700. The Samsung website says that Metro PCS is the only carrier (which I seriously doubt), but doesn't specify the network. I'm thoroughly lost here- in theory, I should be able to take the phone to any other carrier that uses the same network type...right? What other carriers use this phone's network? The phones were expensive, so I'd like to avoid having to purchase new ones if at all possible.
