How do I find out if my phone is CDMA or GSM?
In the About (iOS) or Status (Android) page, scroll down and check for a MEID, ESN, or IMEI number. If your phone has a MEID or ESN number, it uses CDMA, and if it has IMEI, it uses GSM. If you see both, that means your phone supports both GSM and CDMA networks.
Can unlocked CDMA phones work on Verizon?
The short answer is no. If you have an older device that is only equipped with GSM technology, it will never work well on CDMA networks like Verizon, even if it’s an unlocked phone. If you have a phone that’s CDMA only then it won’t work well on GSM networks, like AT and T-Mobile.
