USA eSIM

4G LTE and 5G nationwide across major cities and interstate highways — Excellent in cities and along major highways. Remote national park interiors — Grand Canyon North Rim, Yellowstone backcountry, parts of Yosemite — have very limited or no signal.

Road trip days easily use 500MB–1GB. We recommend 5GB for a 1–2 week visit — it gives you room to stream in the evenings and navigate long driving days without watching every megabyte.

American road distances are consistently underestimated by first-time visitors. What looks short on a map often takes 3–4 hours through mountain passes or national parks. Build in far more driving time than you think you'll need — and always check road closures before setting off.
