Does 4G use CDMA or GSM?

The CDMA/GSM split ended, in theory, as carriers all switched to LTE, a single, global 4G standard, starting in 2010 . But the difference remained because phones still needed to access the older 2G and 3G networks, primarily for voice calls.

As of 2020, about 93.5 percent of the population had access to the 4G LTE mobile network in Malaysia . By comparison about 95.3 percent had access to the former 3G network.

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.

4G LTE is neither CDMA nor GSM but a separate cellular technology that provides the 4G migration path to 3G networks on CDMA and GSM tracks. CDMA2000 is the 3G technology on the CDMA track, and UMTS is the 3G technology on the GSM track. Both UMTS and CDMA2000 use the LTE technology for 4G services.
