The United States is an easy destination to buy for and a slightly harder one to plan for. One country, one plan, no borders to think about — but a landmass where coverage stops mattering in cities and starts mattering a great deal on the drive between them.
What coverage actually looks like
In and around cities, on any major network, you will get fast data and rarely think about it. Away from the interstates, coverage becomes a real variable — and in national parks it is frequently absent by design as much as by geography.
Our USA plans use partner networks with national coverage, and the plans page lists what is included. The practical advice is the same whoever you buy from: if you are driving somewhere remote, assume nothing and download everything.
How much data
Budget higher than you would for Europe. Two reasons: distances mean more time navigating, and free public Wi-Fi is less consistently good than in European cities — plenty of American hotels and cafés still run networks that struggle with a video call.
| Trip | Suggested |
|---|---|
| Long weekend in one city | 2–3 GB |
| One week, city-based | 3–5 GB |
| Two weeks, multiple cities | 10 GB or unlimited |
| Road trip of any length | Unlimited, plus offline maps |
If you are tethering a laptop — working from the trip, or keeping a car full of people entertained — go unlimited and stop doing arithmetic. The per-activity numbers are here.
Things that are specific to the US
- iPhones sold in the US are eSIM-only from the iPhone 14 onwards. If you are buying a phone there, there is no SIM tray to fall back on.
- A data plan is not a US phone number. Some services — a few delivery apps, some store pickups — want one. A travel data eSIM will not provide it.
- Distances are the real planning problem. A three-hour drive in Europe crosses a country; in the US it may not leave a state, and the coverage can change more than the scenery.
- Hawaii and Alaska are included in most national coverage, but confirm before relying on it.
Before you buy
- Check your phone supports eSIM and is unlocked.
- Match the validity period to your trip, not just the data amount.
- If the plan is unlimited, check the daily high-speed allowance.
- Install it at home, over Wi-Fi, before you fly.
