It depends which phone you buy. If the model number ends in C then it is a CDMA phone on Verizon towers. If the model number ends in G it is a GSM phone on AT&T towers, usually ... BUT look at the box it comes in. Some say GSM-A for AT&T and some say GSM-T for T-mobile.
T-mobile coverage in my neck of the woods is not good. Currently AT&T coverage in my area is very good. On the Walmart website, pick a phone and it will let you put in a ZIP code and tell you if the phhone will work in that ZIP code.
Also, Straight Talk and Tracfone do not allow teathering.
