| Provider | Offer | About a week | Lots of data | Bancontact |

| Holafly | Unlimited | 7 days: €23.90 | 30 days: €63.90 | No |
Choose a fixed bundle (esimzu) if you mostly use data for maps, messaging, social media and the occasional video: 10 GB for 30 days costs €7.99, a fraction of an unlimited week plan elsewhere.
Choose unlimited (Holafly or Airalo) if you want to stream and hotspot without thinking about usage and the premium is not an issue.

What to look for when choosing
| Criterion | What to look for in the United States |
|---|---|
| Coverage | Reliable local operators, 4G and ideally 5G |
| Price per gigabyte | The real benchmark, not the total price |
| Validity period | Matches the length of your trip |
| Payment method | Paying by card is simple, instant and trusted |
| Top-ups | Handy if you end up running low |
Anyone who lines up these points side by side almost always makes a good choice. More on this in comparing eSIM providers.
How much data do you need in the United States?
| Type of traveller | Recommended data |
|---|---|
| Light (weekend) | 1 to 3 GB |
| Average (week) | 5 GB |
| Heavy (1 to 2 weeks) | 10 GB |
On a road trip you use a lot through constant navigation, so allow yourself plenty. Our guide how much data do you need when travelling helps you choose.
Outside the EU: when you arrive, turn off the mobile data on your home SIM card and use only the eSIM, to avoid expensive roaming. Your home number stays reachable for calls.
Coverage in brief
In the cities and along the main roads the coverage is excellent, while in national parks the network sometimes drops out. For the full coverage by region, see eSIM United States.
