🇺🇸美国 eSIM 套餐

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.

适合

Business travellers landing in NYC, SF, or Austin; road-trippers needing coast-to-coast LTE; visitors who just want to skip the airport AT&T kiosk line.

网络

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.

旅行小贴士

5G works on most modern phones, but coverage is patchier in rural areas — 4G LTE is the dependable everyday speed across the country.
