Does H2O Wireless use CDMA or GSM?

CDMA and GSM are the two technologies used in cell phones and help fill in the gap when 4G is not available. If your phone is only a few years old it's likely to be compatible with both technologies which make it easy to switch carriers.

AT&T uses the GSM network so H2O Wireless is compatible with all GSM phones. Don't worry if your phone is not using the same technology, you can still save money on your cell phone plan. If you want to check your phone's compatibility you can use our IMEI checker.
