Austria eSIM Guide: A1, Drei and Coverage in the Alps
Austria combines two very different kinds of trip: city breaks in Vienna and Salzburg, and time in the Alps, whether for skiing in winter or hiking in summer. Cities and resort towns are well covered. Mountain valleys, high trails and remote passes are where you'll notice which network your plan uses.
Which networks Austria eSIMs use
Austria has three mobile networks: A1, Magenta Telekom and Drei (the Three brand). Among the wholesale Austria plans we track:
| Plan type | Networks | Where data exits |
|---|---|---|
| Roaming, two networks | Drei, A1 (5G) | France, Netherlands or UK |
Two networks give your phone a fallback in the mountains, where one operator may reach a valley the other doesn't. Data exits outside Austria, so websites may appear in another language. Maps use GPS and aren't affected. More on routing in what a travel eSIM is.
Coverage
| Area | What to expect |
|---|---|
| Vienna, Salzburg, Innsbruck, Graz | Strong 4G and 5G |
| Vienna U-Bahn | Coverage in stations and tunnels |
| Hallstatt and the Salzkammergut lakes | Good in villages; weaker on lakeside trails |
| Ski resorts (St. Anton, Kitzbühel, Ischgl, Sölden) | Good in villages and on main lifts and pistes |
| High Alpine trails and huts | Patchy; some huts have Wi-Fi |
| Railjet trains | Mostly covered, with drops in Alpine tunnels |
In the mountains
For hiking and ski touring:
- Download offline maps of the area before leaving the valley.
- Check the weather and avalanche bulletins from official regional services in the morning while you have signal.
- Keep your phone warm in winter. Cold drains batteries quickly; carry it in an inside pocket and bring a power bank.
- Save the number of your accommodation and the local mountain rescue, and know that 140 is Austria's Alpine emergency number.
Motorway vignettes
Driving on Austrian motorways and expressways requires a vignette (toll sticker), which you can also buy as a digital vignette linked to your number plate. Buy it from the official ASFINAG website or app, or at a petrol station before you cross the border. Some unofficial websites sell vignettes with an added fee.
Before you fly: a short checklist
- Install the eSIM at home over Wi-Fi and leave it switched off until you land or cross the border.
- Buy a motorway vignette from official channels if you're driving.
- Download offline maps for any valley or trail area you'll visit.
- Save ski passes, lift tickets and hut bookings as screenshots.
- Pack a power bank, especially for winter trips.
Combining Austria with neighbours
Austria borders eight countries, and many trips combine Vienna with Prague, Budapest or Munich, or the Tyrol with Switzerland or Italy's Dolomites. Points to check:
- Switzerland and Liechtenstein are outside the EU and not on every Europe plan.
- Germany, Italy, the Czech Republic, Hungary and Slovakia are in the EU and usually included.
- Near borders and on ski runs that cross them, phones may connect to the neighbouring country's network.
Our Germany guide, Europe guide and multi-country guide cover these combinations.
Getting around
ÖBB's app shows train tickets and live departures across Austria, and Vienna's public transport app (Wiener Linien) covers the U-Bahn, trams and buses. Ride-hailing apps such as Uber and Bolt operate in Vienna. In ski resorts, free ski buses connect villages and lifts.
How much data you'll need
| Trip | Suggested data |
|---|---|
| 3 to 4 days in Vienna | 2 to 3 GB |
| A week, Vienna, Salzburg and Hallstatt | 5 GB |
| A ski week with lift apps and hotspot for family | 5 to 10 GB |
| 2 weeks of hiking in the Tyrol | 5 to 8 GB, with offline maps |
Hotels and many mountain huts offer Wi-Fi. The data guide has per-activity figures.
Setting up and troubleshooting
Install the eSIM at home over Wi-Fi and switch it on after landing in Vienna, Salzburg or Innsbruck, or after crossing the border. Set it as your cellular data line and enable data roaming for it. If there's no service, toggle airplane mode, then select A1 or Drei manually. The troubleshooting guide covers the rest.
Emergency calls
The European emergency number 112 works throughout Austria. Austria also has dedicated numbers: 133 for police, 144 for ambulance, 122 for the fire service and 140 for Alpine emergencies.
FAQ
Do Austria eSIMs include an Austrian number?
Most travel eSIMs are data-only. Local prepaid SIMs require registration.
Will my eSIM work on the ski slopes?
On main lifts and pistes, generally yes. Off-piste and in some side valleys, coverage is patchy.
Does an Austria plan work in Switzerland?
Only if Switzerland is on the list. Many Europe plans include it, but not all.
Do I need a vignette for Austrian motorways?
Yes, for cars on motorways and expressways. Buy it from official channels before you drive on them.
Is there signal in Hallstatt?
Yes in the village. On the trails above the lake, it varies.
