Summary
GSM networks are still used in the US, primarily by AT&T and T-Mobile. However, different carriers in the US use different bands, and CDMA technology is also utilized. Verizon, the largest wireless carrier in the US, uses CDMA technology. GSM networks are also used by various MVNOs powered by AT&T and T-Mobile, such as Boost Mobile, Mint Mobile, Red Pocket, and Tello.
Major US cellular networks have phased out legacy 3G support in 2022. AT&T shut down its 3G GSM network, T-Mobile began shutting down parts of its network, and Verizon officially retired its legacy network. As a result, it is recommended to switch to a 4G or 5G phone if you still have a phone that only uses 2G or 3G.
Verizon primarily uses its 4G LTE network for both basic phones and smartphones. They have decommissioned their CDMA network as of January 3, 2023. AT&T currently holds the title of the largest telecommunications company and mobile phone service provider in the US.
