It is both a CDMA and GSM phone. It is dual meaning you can use either type of chip. I highly suggest this phone. I love it. The people at Cricket thought the phone was a Galaxy at first and couldn't believe it wasn't.

No, this phone is capable just for 2G and 3G, GSM and HSDPA networks respectively. For 4G you need a phone capable to operate in CDMA network.

No, Verizon is CDMA, I do not believe there are any CDMA watches out there yet, so far there's only GSM like AT&T & Tmobile.

No. Verizon and Sprint are CDMA. This is a GSM phone which is what AT&T; and T-Mobile and most of the rest of the world use.

Sorry this is cdma phone. U.S market only. To be sure check with your service provider. However an unlocked phone should be ok to use anywhere in the world. Good luck

This phone works with AT&T.; I have been using it with AT&T; for 6 months. GSM means the phone uses a SIM card. CDMA does not.
