My phone says GSM but I only have Verizon towers around, will it work or should I return it? Waiting to receive it in the mail and it came to me after I bought it that I needed to buy a phone that was CDMA
It might work to a degree. GSM/CDMA is mainly a concern with 2G/3G connections. Once you get into 4G LTE, most of those network bands overlap. Do a Google search on your phone model, find out what network bands it supports, and see if any of it matches up with Verizon's networks.
