Hi guys.. look there are some phones that have dual sim cards and what not but have the same frequency but what am i looking for to work on sprint? i know 1900 but please help me find out what else i need to know.
Sprint does not use SIM cards, only GSM carriers like AT&T and T-Mobile do, along with iDEN carrier Nextel. Though Nextel's SIMs are NOT compatible with AT&T/T-Mobile. NOTE: Some Sprint phones have "World" capability (which means it has GSM technology and a SIM for use around the world, as a majority of countries operate on GSM-based networks). You will need to get a Sprint branded phone. Sprint uses CDMA network technology. Sprint is notoriously difficult about getting non-Sprint phones to work on their network. Some say it can be done, but it's difficult to say how successful you'd be. Sprint phones generally have the 850 & 1900 frequencies. Sprint's native network runs on 1900, but the 850 is there for additional coverage on approved roaming carriers (like Verizon or US Cellular, and others). Another important point with Sprint phones, if you find a compatible phone via eBay, make sure to get the ESN (electronic serial number) from the seller to verify whether the ESN is clean. If it's not, Sprint won't activate it.
