As Listed in the Specifications: AT&T, T-Mobile, Cricket, TRACFONE, Net10, Simple Mobile, H2O Wireless (Basically All GSM Based Networks) CDMA is Owned by Qualcomm, In the US, Sprint, Verizon and US Cellular use CDMA. AT&T and T-Mobile use GSM. Most of the rest of the world uses GSM. The global spread of GSM came about because in 1987, Europe mandated the technology by law, and because GSM comes from an industry consortium. Unless you are contracted to a CDMA provider, GSM is the better direction.
Sorry, there was a problem. Please try again later.From Kodak's web site: Network Compatibility: The KODAK EKTRA is an open market unlocked GSM (Global System for Mobile Communications) device, which means it is compatible and will work on the AT&T and T-Mobile networks in the USA. It is not CDMA (Code Division Multiple Access) compatible so will NOT work with Sprint, Verizon or US Cellular.
