American trips split into two shapes and they want different plans. A city trip — New York, Chicago, Los Angeles — still adds up: maps, transit apps, restaurant lookups and messaging together are worth around 3GB a day, or a 20GB total, rather than the smallest tier. A road trip is a different animal. Navigation runs for six hours a day, cell service comes and goes through the mountains and the desert, and you end up re-downloading directions every time you regain signal. For that pattern, 2–3GB per day or an unlimited plan is the honest recommendation.
| Plan | Network | Plan styles | Trip length | Best for |
|---|---|---|---|---|
| USA eSIM | AT&T and Verizon | 5/10/20GB total, 1/2/3GB per day, or unlimited | 3–30 days | City breaks, road trips, business travel, national parks |

It connects directly to AT&T and Verizon, the two largest carriers in the United States. That is what gives it usable coverage on the interstates and in the national parks, rather than only in the major cities.
No. You scan a QR code and the profile installs. There is no store visit, no US address, no credit check and no physical SIM to swap out.
For a city-based trip, 1GB per day is comfortable. For a road trip, choose 2–3GB per day or unlimited, because continuous navigation over long distances uses far more than people expect.
Coverage in the parks follows the AT&T and Verizon footprint, which is the best you can do with any carrier. Expect strong signal at the main entrances, visitor centres and nearby towns, and dead zones deep in the backcountry — that is true of local US SIM cards too. Download offline maps before you drive in.
These are data plans. Calls and messages work through internet-based apps — WhatsApp, LINE, FaceTime, Messenger — rather than a traditional voice line.
