Mobile coverage in United States
3 carriers support Roamgo eSIMs in United States. Tap any operator below to see their official coverage map.
Your phone won't auto-pick a US carrier when you land — most foreign plans either don't include the US or roam at punitive day rates. A Roamgo eSIM swaps in a local-network data plan before you clear customs, so Apple Maps and Uber work on the curb outside JFK or LAX.
Networks: Roams onto AT&T, T-Mobile, and Verizon (depending on the local cell tower) — the three major US carriers cover roughly 99% of populated areas with 4G LTE or 5G.
