From the ST website:
How to Choose a Network
If you live in an area served by both carriers, the Straight Talk website will offer you phones from both carriers. However, if you know Verizon (or AT&T) has better coverage where you live, you will probably want to get a phone that works on the better network.
While not explicitly providing this information on their website, Straight Talk has made it easy to tell. Just look at the letter code at the end of the phone model. If it is a “G”, it is a GSM phone and will work over AT&T; if a “C” it is a CDMA phone and will work over Verizon. For example, the LG100C is a CDMA phone, while the LG620G is a GSM phone.
