Roaming in Hong Kong on an Austrian plan: what A1 and Drei charge
Hong Kong 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 5 GB planning size (7 days), A1’s Roaming Pass would bill 5 × €5.90 = €29.50; 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 |

Common questions
Is 5 GB enough for 7 days in Hong Kong?
Hong Kong is dense and compact: MTR rides, maps and messaging are normal use. Saily lists Hong Kong plans from 1 GB for 7 days up to 20 GB for 30 days, plus unlimited options — data only, without a local number. 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 Hong Kong instead?
Hong Kong 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.
