Roaming in Sri Lanka on an Austrian plan: what A1 and Drei charge
Sri Lanka 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 2) | per started GB | €5.90 |
| Drei | Roaming-Paket Go | 1 GB, 15 days | €5.00 |
| Drei | Roaming-Paket Go Select | 5 GB, 15 days | €10.00 |
For the 20 GB planning size (30 days), A1’s Roaming Pass would bill 20 × €5.90 = €118.00. 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. 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.
Planning size
| Habits | 30-day range | Planning size |
|---|---|---|
| Normal (maps, messages, social) | 12–18 GB | 20 GB |
| Normal + daily video | 30–45 GB | 50 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.
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 Sri Lanka?
Train rides through the hill country, tuk-tuk trips and beach days fit normal use. Saily lists Sri Lanka 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 Sri Lanka instead?
Sri Lanka is outside EU roaming. As of 22 Oct 2026, A1’s Roaming Pass bills €5.90 per started GB there (zone 2) and Drei sells 1 GB for €5 or 5 GB for €10, valid 15 days. Compare that with an eSIM quote for the same GB.
