In the US, AT&T as well as T-Mobile phones use GSM – and most of the rest of the world uses GSM as well. CDMA in the US is Verizon, Sprint and US Cellular. You need to read up on the subject.
Read moreIs GSM same as 4G?
GSM is a second-generation (2G) cellular technology standard and is, therefore, less capable of providing high-speed data as compared to UMTS, which is a third-generation (3G) technology and LTE, which is a fourth-generation (4G) cellular technology.

Read moreHow does 5G transmit data?
Like other cellular networks, 5G networks use a system of cell sites that divide their territory into sectors and send encoded data through radio waves . Each cell site must be connected to a network backbone, whether through a wired or wireless backhaul connection.
Read moreWhat hardware is required for 5G?
Multichannel, highly integrated RF transceivers are the core piece of the 5G hardware puzzle. An RF signal bandwidth up to 1 GHz is required, with the possibility to operate in multiband. Implementing an RF sampling technique enables the described characteristics in a simpler architecture and with reduced cost.
