It is a network protocol issue. Verizon and Sprint are CDMA, AT&T and T-Mobile (and the rest of the world) are GSM. Your phone will work on one spec or the other, and depending on the spec you will have two carriers to choose from if you were to get an unlocked phone.
- DenisM 17y agoThings change. When it comes to 4G Verizon has abandoned EV-DV (Qualcom/CDMA family) and instead committed to LTE (GSM family). What this means is that come 4G there will be one standard across all major carriers both in states and in Europe. (I can't imagine Sprint having enough money to justify further EvDv R&D so they will have to switch as well). Verizon is hard at work rolling out LTE equipment as we speak.
- fpgeek 17y agoSeeing that play out will be interesting. I don't know how many people (like me) stick with AT&T and T-Mobile because they insist on having a phone that will work overseas, but I'd bet we're among the more profitable consumers...
