Is AT&T a CDMA or GSM network?
GSM stands for Global System for Mobile Communications. GSM and CDMA are the 2 types of 3G networks that cell phone carriers use to provide your service.
In the past, you couldn't use a CDMA network's phone on the GSM network and vice versa. However, most newer smartphones can operate on either type of service.
Some older phones can as well, just make sure you research your specific device to find out whether it's compatible with both before buying a cell phone plan.
AT&T GSM network carriers
If you're shopping around for a new carrier, consider MVNOs - Mobile Virtual Network Operators. These are smaller mobile providers that rent space on the same networks the big guys use and then sell it to you at a lower price.
