Does WCDMA support CDMA?
UMTS uses a wideband version of CDMA occupying a 5 MHz wide channel. Being wider than its competition CDMA2000 which only used a 1.25MHz channel, the modulation scheme was known as wideband CDMA, or WCDMA / W-CDMA. This name was often used to refer to the whole system.
Can a phone work on both CDMA and GSM?
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.

What carrier uses WCDMA?
WCDMA was the 3G technology used in the US by AT and T-Mobile. There are several newer upgrades to WCDMA that offer much faster data speeds, such as HSDPA and HSPA+. These do not replace WCDMA, but rather build on and enhance WCDMA. Therefore any phone with HSDPA or HSPA+ also includes WCDMA by definition.
Is CDMA and WCDMA same?
The main difference between WCDMA and CDMA is that they are designed to work with different networks. WCDMA is a 3G technology designed to work alongside the 3G GSM network. CDMA, on the other hand, is a 2G technology that is a direct competitor to GSM.
Is VoLTE a CDMA?
VoLTE stands for Voice-over-LTE. VoLTE allows you to make and receive calls using your phone’s data, with your existing Red Pocket Mobile phone number. You must have a VoLTE-compatible phone. For the GSMT, GSMA, and CDMA networks, VoLTE can be used with all VoLTE-capable phones.
