The Cellular Telecommunications & Internet Association (CTIA), lists approximately 30 facilities-based wireless service providers in the United States as members.

The top 5 wireless telecommunications facilities-based service providers by subscriber count in the United States are:

Each active SIM card is considered a subscriber. Wholesale customers include Machine to machine and Mobile Virtual Network Operator customers that operate on the host network, but are managed by wholesale partners. Verizon Wireless does not report wholesale subscriber count. For comparison purpose, the total subscriber count for Verizon Wireless includes an estimated number of wholesale customers.

The top 5 wireless providers have all standardized on 4G LTE as their wireless communication standard, which has been deployed across the entire coverage; however, the LTE bands used by each provider remain largely incompatible. All 5 wireless providers also maintain legacy networks; of these, AT&T and T-Mobile use 2G GSM/EDGE and 3G UMTS (mostly converted to 4G HSPA+), while Verizon, Sprint, and U.S. Cellular use cdmaOne/EV-DO/1xRTT. While the top 4 wireless providers operate nationwide wireless networks which cover most of the population in the United States, U.S. Cellular and other smaller carriers provide native network coverage across selected regions of the United States while supplementing nationwide coverage through roaming agreements with other carriers.
