United States eSIMHow much eSIM data for 7 days in the United States?
✓ Prices checked 22 Oct 2026For 7 days in the United States with normal daily use, TripUtils estimates 3–5 GB. A 5 GB plan is the usual buffer. Not a live price. Maps and messaging still fit normal use. US unlimited-home-plan mental models do not apply to a prepaid travel eSIM — pick a GB cap from the range, then open the provider.

Roaming in the United States on an Austrian plan: what A1 and Drei charge
The United States is outside EU roam-like-at-home, so the EU data in an Austrian plan does not apply there. Published prices, checked on 22 Oct 2026 (euros incl. VAT):
| Network | Option | Data | Price |
|---|---|---|---|
| A1 | Roaming Pass (Zone 1) | per started GB | €4.90 |
| A1 | A1 Roaming Datenwoche Welt | 1 GB, 7 days | €9.90 |
| Drei | Roaming-Paket Go | 1 GB, 15 days | €5.00 |
| Drei | Roaming-Paket Go Select | 5 GB, 15 days | €10.00 |
| Drei | Roaming-Paket Nordamerika Unlimited | unlimited, 15 days | €35.00 |
For the 5 GB planning size (7 days), A1’s Roaming Pass would bill 5 × €4.90 = €24.50, the A1 Roaming Datenwoche Welt 5 × 1 GB = €49.50 (packages run 7 calendar days, Austrian time, and can be stacked); on Drei, 1 package (Go Select) cover it for €10.00. A1 says the Roaming Pass is switched on automatically for every tariff signed since 24 June 2026, and it blocks roaming data at a default limit of €60, which you can raise yourself.
Magenta prices depend on the tariff — look them up in Magenta’s roaming finder. Older tariffs without these options can cost more. Sources: A1, Drei, Magenta.
Planning size
| Habits | 7-day range | Planning size |
|---|---|---|
| Normal (maps, messages, social) | 3–5 GB | 5 GB |
| Normal + daily video | 7–11 GB | 15 GB |
Assumptions and sources
Light 0.20 / normal 0.50 / heavy 0.95 GB per day, plus optional extras, plus about 20% buffer. No live retail prices.
Holiday weeks and national-park summers lift stays; nationwide data still follows the GB model, not the state.
These are planning ranges, not live prices.
Common questions
Is 5 GB enough for 7 days in the United States?
Maps and messaging still fit normal use. US unlimited-home-plan mental models do not apply to a prepaid travel eSIM — pick a GB cap from the range, then open the provider. The 3–5 GB estimate plus buffer lands on 5 GB. Hotel Wi‑Fi is not counted. Streaming video on mobile is the usual reason to go larger.
Should I roam in the United States instead?
The USA is outside EU roaming. As of 22 Oct 2026, A1’s Roaming Pass bills €4.90 per started GB there (zone 1) and Drei sells 1 GB for €5, 5 GB for €10 or “Nordamerika Unlimited” (unlimited) for €35, valid 15 days. Compare that with an eSIM quote for the same GB.
