USA eSIM guide: New York, road trips and the national parks
Updated November 2026
A US eSIM runs on T-Mobile, AT&T or Verizon and covers the cities, the interstates and Hawaii. Roaming in the US is expensive on most European and Turkish plans, which is why visitors use an eSIM here. It is data only, so you do not get a US number; your own SIM stays in the phone for calls and bank codes. In big national parks, expect long stretches with no signal at all.
What a trip costs
| Trip | eSIM price |
|---|---|
| New York at Christmas or New Year (5 days) | 3 GB · 30 days: €8.99 |
| New York city break (7 days) | 5 GB · 30 days: €10.99 |
| California or Florida (14 days) | 10 GB · 30 days: €17.99 |
| Road trip or long stay (30 days) | 20 GB · 90 days: €27.99 |
Live prices in euros. Unlimited plans are also available for heavy use; the connection never stops (fair usage policy applies).
