Roaming in Mexico on an Austrian plan: what A1 and Drei charge
Mexico 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 | 2 GB, 7 days | €4.90 |
| 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 20 GB planning size (30 days), A1’s Roaming Pass would bill 20 × €4.90 = €98.00, the A1 Roaming Datenwoche 10 × 2 GB = €49.00 (packages run 7 calendar days, Austrian time, and can be stacked). 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. Drei packages last 15 days, so a longer trip needs packages for each period.
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.

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.
Data use follows your phone habits, not the season. Count only the days you will rely on mobile data rather than hotel Wi‑Fi.

Common questions
Is 20 GB enough for 30 days in Mexico?
Cancún, the Riviera Maya or Mexico City are normal use for maps and messaging. Saily lists Mexico plans from 1 GB for 7 days up to 20 GB for 30 days, plus unlimited options. The 12–18 GB estimate plus buffer lands on 20 GB. Hotel Wi‑Fi is not counted. Streaming video on mobile is the usual reason to go larger.
Should I roam in Mexico instead?
Mexico is outside EU roaming. As of 22 Oct 2026, A1’s Roaming Pass bills €4.90 per started GB there (zone 1), the A1 Datenwoche gives 2 GB for 7 days for €4.90, and Drei sells 1 GB for €5, 5 GB for €10 or unlimited data (“Nordamerika Unlimited”) for €35 (15 days each). Compare that with an eSIM quote for the same GB.
