Free eSIM for Austria

Free for new users · Credit card for identity verification only — never charged · Valid 3 days
Why an eSIM beats an Austrian prepaid SIM
Austria has the most competitive mobile market in Europe — you can genuinely buy a prepaid SIM for €9.90 at a Billa or Spar supermarket. But activation requires passport registration since 2019 under anti-terror legislation, which means a trip to a Bipa or T-Mobile Magenta store with ID. A 99esim skips all that — install the profile, land at Vienna Schwechat, and you're connected to A1 as the jet bridge reaches the gate.
- Skip the passport-registration requirement for Austrian SIMs (since 2019)
- Works from Vienna to the remotest Tirolean alm
- Keeps your home number for bank TAN codes and 2FA
- 3 GB is plenty for a Vienna + Salzburg + Innsbruck long weekend
How Austrian networks handle 99esim
99esim rides on A1 Telekom Austria's network — the former PTT and still the operator with the deepest alpine coverage, including the Grossglockner High Alpine Road and the Silvretta pass. 5G is lit in 2,000+ municipalities thanks to Austria's early-mover 3.5 GHz auction. ÖBB Railjet coverage is strong across the Westbahn corridor at 230 km/h.
Arriving at an Austrian airport
Vienna Schwechat (VIE) is the dominant hub with full 5G at every gate and the CAT platform. Regional airports also have solid coverage. Activate before boarding — your phone connects to A1 the moment airplane mode comes off.
CAT train to Wien Mitte (16 min, €14.90) or S7 S-Bahn (25 min, €4.30) both keep signal intact. Terminal 3 has the fastest 5G.
Bus 2 to Salzburg Hauptbahnhof (20 min) runs every 10 minutes — 4G holds the whole way. Perfect for Sound of Music tour app setup before leaving the airport.
Smallest of Austria's main airports but strategically placed. Bus F to Innsbruck Hauptbahnhof (15 min) stays fully online — gateway to ski resorts in Tirol.
Regional hub in Styria. Bus 631 to Graz Hauptbahnhof (22 min) keeps signal on the rural stretch. Gateway to the Südsteiermark wine route.
Mostly domestic and regional flights. Bus 601 to Linz Hauptbahnhof (20 min) — full signal through the Danube valley approach.
Carinthian gateway. Bus 42 to Klagenfurt Hauptbahnhof is short — 4G stays online the whole 15-minute ride.
Where your free eSIM works best
What 3 GB actually gets you in Austria
Austrian trips combine city museums, ÖBB trains and alpine navigation. A realistic breakdown of how 3 GB stretches:
Austria-specific travel tips
Alpine tunnels and toll roads
Austria's autobahns require a Vignette sticker. The Arlberg, Felbertauern and Tauern tunnels are long and mostly signal-dead — load offline maps before entering. Your eSIM reconnects instantly on the far side.
Ski resort coverage has improved
A1 invested in 5G across the major ski areas (Ski Amadé, Kitzbühel, St. Anton, Ischgl) post-2021. Expect signal on lifts and at mountain huts. Smaller resorts in Osttirol can still drop on the higher pistes.
Wiener Linien U-Bahn DAS
Vienna's U-Bahn lines U1, U2, U3 and U4 have distributed antenna systems — you'll hold signal in tunnels. The older U6 (which runs mostly above ground anyway) is fine. Trams and buses all work normally.
Danube river cruise coverage
Wachau valley cruises (Melk to Krems) stay connected on A1 — the river runs through valleys but riverbank masts are dense. International sailings to Bratislava or Budapest switch to Slovak and Hungarian networks — both covered on your 99esim.
Liechtenstein is nearby
If you day-trip to Vaduz from Bregenz or Feldkirch, Liechtenstein is covered by Salt FL or Swisscom FL via the 99esim Switzerland profile. No border surcharge, no manual switching.
Travelers who used 99esim in Austria
"Used it for a week in Vienna and a day trip to Wachau. Signal held on the Danube cruise and through the U1 tunnels under the Danube."
"Skied in St. Anton — 5G at the top of the Galzig lift was surprisingly fast. Uploaded ski videos from the mountain."
"Road-tripped the Grossglockner High Alpine Road. Only lost signal in the longest tunnel. Reconnected in seconds at every overlook."
Frequently asked — Austria edition
Does the free eSIM work on the Vienna U-Bahn?
Yes. Wiener Linien has fitted U1, U2, U3 and U4 with distributed antenna systems — 4G is steady in tunnels and at every station. U6 runs largely above-ground so coverage is naturally constant. Expect rare drops only in the deepest sections.
Can I use it in the Austrian ski resorts?
Yes. A1 has extended 5G to all major Ski Amadé, Kitzbühel and Arlberg ski areas. Smaller resorts like Hochzillertal and Silvretta Montafon have 4G at base stations with spotty coverage on higher lifts. Always useful to have offline maps.
Will it work on the Railjet to Salzburg or Innsbruck?
Yes. ÖBB and A1 completed trackside coverage on the Westbahn in 2022. Expect steady 4G at 230 km/h with brief drops in the Wienerwald and Arlberg tunnels. Overall journey holds signal 90%+ of the route.
Is 5G included on the free 3 GB plan?
Yes. If your device supports 5G and you're in a covered municipality (all nine state capitals, most towns and ski resorts) the free eSIM uses 5G automatically. Data counts the same as 4G.
Can I tether to a laptop or second device?
Yes, tethering works on the free plan. Keep an eye on usage — streaming and cloud syncs burn through 3 GB fast. A standard Zoom call over tether uses 500 MB per hour.
What if I run out mid-trip?
Top up in the 99esim app instantly — Austria-specific add-ons start at €2.99 for 1 GB. No auto-renewal, no saved-card charges, no trip back to a Bipa store required.
