Roaming in Montenegro on an Austrian plan: what A1 and Drei charge
Montenegro 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 |
For the 5 GB planning size (7 days), A1’s Roaming Pass would bill 5 × €4.90 = €24.50, the A1 Roaming Datenwoche 3 × 2 GB = €14.70 (packages run 7 calendar days, Austrian time, and can be stacked); on Drei, 5 packages (Go + Go + Go + Go + Go) cover it for €25.00. 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.

| Habits | 7-day range | Planning size |

Common questions
Is 5 GB enough for 7 days in Montenegro?
Coast maps, boat trips and beach days around Kotor and Budva fit normal use. Montenegro pays in euro but is not in the EU — euro prices do not mean EU roaming. 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 Montenegro instead?
Montenegro 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 (valid 15 days). Compare that with an eSIM quote for the same GB.
