United States: Mobile Coverage & Carriers
The United States has three major mobile network operators: AT&T, T-Mobile, and Verizon. These carriers have commercially launched 3G, 4G/LTE, and 5G networks. A roaming eSIM in the US will typically access LTE bands including B2 (1900 MHz), B4/B66 (AWS), B12/B13 (700 MHz), and B71 (600 MHz). On 5G, the key bands are n71 (600 MHz), n41 (2.5 GHz), n77/n78 (3.7 GHz), and n258 (mmWave).
All three local carriers issue eSIMs, making it straightforward for travelers to activate local connectivity on compatible devices. The combination of extensive LTE coverage and growing 5G deployment across multiple bands ensures broad geographic reach throughout the country.
