Detailed explanation-1: -Network carriers such as AT&T and T-Mobile use GSM. If a carrier uses GSM, users can remove their SIM card from a device and move it to another mobile device with all the same data and contacts on it. The network carrier will still be able to identify the user as well.
Detailed explanation-2: -What does the CDMA/GSM difference mean? One major distinction between GSM networks and CDMA networks is that the former allows you to make voice calls and transmit data at the same time, while the latter does not. But there’s a catch. GSM and CDMA standards apply to 2G and 3G connectivity.
