Pros: Lowest price per GB, fast activation, Austria coverage on 3, A1.net. Cons: Newer brand, smaller community than Airalo.
Austria supports 2 eSIM carriers: 3 and A1.net, both on 5G. Drei (3) holds the largest subscriber base and offers competitive pricing. A1.net runs Austria's oldest network with deep alpine penetration.
Both carriers deliver 5G in all major cities. Your e-sim auto-selects the strongest signal at arrival.
Coverage analysis
A1 Telekom Austria anchors the deepest alpine coverage, with 5G across Vienna's U-Bahn subway stations and dedicated repeaters inside the Wiener Linien underground network. Innsbruck and the Inn Valley corridor hold strong 4G, but Tyrolean side valleys like the Stubaital and Ötztal lose signal above 2,000 meters where cell towers thin out between ski resorts. Drei (3) fills urban gaps well in Graz and Linz, though the Hohe Tauern high-alpine zone remains a dead spot for both carriers above the Grossglockner pass road.
Activation
Install your eSIM before boarding at VIE or SZG (Salzburg airport). Both 3 and A1.net register automatically on arrival. The ÖBB rail network holds consistent 4G signal except inside the Arlberg Tunnel (14 km, no service).
Tethering is enabled on all 7 plans, so you can share data with a laptop.
Data usage tips
Google Maps offline for Austria saves 300-400 MB and covers alpine hiking routes. The Wien Mobil transit app uses under 20 MB per day. Salzburg Museum digital guides add 50-100 MB per visit.
Streaming at HD quality on TIM burns 700 MB per hour; drop to standard definition for 300 MB per hour.

Does my phone support eSIM in Austria?+

The top-up option means you can start with a small 3 GB plan at $4.99 and add data if Vienna sightseeing runs over budget.
