Is 5G 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.

The general rule is that a CDMA phone wont work on a GSM network , and vice versa—they run on different frequencies. However, most new iPhones like the 8 and 8 Plus and some Google Nexus phones CAN run on both technologies. Before you switch, make sure you check whether your phone is compatible first.

One of the biggest differences between these two systems is that GSM phones use SIM cards to link a particular phone with its network, while CDMA phones don’t require a SIM card because the phone itself is linked to the network .

In summary, neither GSM nor CDMA is technically better . They ultimately provide the same service, and the quality of a network depends on the carrier, not the cellular standard used. Second, GSM phones can be unlocked and switch carriers, whereas CDMA phones are locked to a carrier.15 Oca 2022
