A1 is the prepaid SIM to reach for if your Austria trip touches the Alps, since it has the deepest valley and ski-resort coverage and starts around EUR 9.90; for a city-only stay the supermarket brands HoT (on Magenta) and spusu (on Drei) undercut everyone from about EUR 5 a month. The catch unique to Austria is registration: a 2019 law means every prepaid card, even a Hofer supermarket SIM, has to be activated against your passport before it works, so a counter visit and ID check are unavoidable with a local card. A travel eSIM sidesteps that paperwork entirely and is live the moment you land, see our Austria eSIM guide to compare, or let the eSIM Finder size a plan for you.

Austria's Mobile Landscape
Austria runs on three network operators: A1, Magenta (the former T-Mobile Austria), and Drei (Three Austria). On top of those sit a clutch of cut-price virtual brands that ride the big networks, most famously HoT, sold in every Hofer (Aldi) supermarket on the Magenta network, and spusu, which runs on Drei. That layer of discounters is what makes Austrian prepaid data unusually cheap by European standards.
For a visitor the decision is less about price than about where you are going. In Vienna, Salzburg, Graz, and Innsbruck all three networks are excellent and the cheap brands are perfectly good. The moment you head for Hallstatt, a ski valley, or the Grossglockner High Alpine Road, the picture changes: A1 reaches furthest into the mountains, which is why it commands a price premium and why the budget brands, riding Magenta or Drei, can leave you with fewer bars in a side valley.
Every Austrian SIM needs passport registration
Since 1 January 2019, Austrian law requires photo-ID verification for every prepaid SIM before it can be activated. Anonymous cards no longer exist. Provider shops register you on the spot for free, while partner shops such as Hartlauer or MediaMarkt may charge up to EUR 10 for the service. Bring your passport, and budget a few minutes for the check. This is the single biggest friction point that a pre-registered travel eSIM removes.
A1
A1: The Alpine Coverage Standard
Austria's largest network, rated first for coverage and the one that reaches the mountains
A1 is the default local SIM for anyone whose plans go beyond the cities. Independent testing and Austria's regulator both rank it first for overall coverage, and it has put the most money into mountain infrastructure, so it holds a signal at gondola bases, resort villages, and pass viewpoints where the budget brands fade. Its prepaid B.free packs bundle data with Austria minutes, and seasonal tourist packs push the data allowance up to the tens of gigabytes.
You pay a premium for that reach, with entry prepaid plans from around EUR 9.90 against roughly EUR 5 for the supermarket brands, but for a Hallstatt, ski, or Grossglockner trip it is money well spent. Buy in an A1 shop or a Trafik (the Austrian tobacconist-newsagent) and let them complete the passport registration before you leave.

Magenta
Magenta: The Speed Leader
Former T-Mobile Austria, winner of the fastest 5G speed awards
Magenta is the network to pick if raw speed in town is your priority. It took the latest awards for the fastest 5G download and upload speeds in Austria, so in Vienna, Graz, Linz, and Innsbruck you get genuine performance on top of solid coverage. Its prepaid range is straightforward, and crucially it is also the network behind HoT, the supermarket brand below, so you can get Magenta-grade city coverage for a fraction of the headline price. Rural and high-Alpine reach trails A1, so it is a stronger pick for a city-focused trip than for a deep mountain one.
Strengths
Weaknesses
Drei, HoT and spusu
Drei: Best-Network Award Winner
Strong city 5G and the latest Opensignal best-network title
Drei took the overall best-network award in the latest Opensignal report and posts city 5G availability essentially level with A1 and Magenta, so in Vienna and the other cities it is a genuinely strong, often cheaper option. Its reach is the thinnest of the three in remote Alpine terrain, so it suits a city-and-valley trip more than a high-mountain one.
The supermarket budget brands
HoT rides the Magenta network and is sold at every Hofer (Aldi) supermarket from around EUR 5.90 a month, making it the easiest cheap SIM to grab while shopping. spusu runs on Drei and starts near EUR 4.90 for a 2 GB pack, the cheapest headline price in Austria. Both still require the same passport registration, but they are the value champions for a city stay where you do not need A1's Alpine reach. Note that the cheapest supermarket SIMs sometimes need online photo-ID activation, which is easiest for EU citizens.
Austria SIM Card Plans Compared
| Carrier | Network | Typical Price | Best For |
|---|---|---|---|
| A1 B.free | A1 | From ~EUR 9.90 | Alps, ski resorts, all-round |
| Magenta Klax | Magenta | ~EUR 8 to 25 | Fastest city 5G |
| Drei prepaid | Drei | From ~EUR 8 | City use, strong 5G value |
| HoT (Hofer) | Magenta | From ~EUR 5.90 | Cheap city data at the supermarket |
| spusu | Drei | From ~EUR 4.90 (2 GB) | Cheapest headline price |
Prices above are typical 2026 monthly prepaid rates. EU free-roaming is included on all of them, so an Austrian SIM also works at no extra charge if you nip across to Bavaria or Italy, though Switzerland sits outside the EU and is not covered. The numbers are honest in Austria, so the table is mainly about matching the network to your trip rather than dodging an airport markup.
Where to Buy a SIM Card in Austria
Carrier Shops (Most Help)
A1, Magenta, and Drei all run stores on Vienna's Mariahilfer Strasse and in the centres of Salzburg, Graz, Linz, and Innsbruck. Staff complete the mandatory passport registration on the spot, load the right pack, and confirm data works before you leave, which is the smoothest way to handle Austria's ID rule.
Vienna Airport (VIE)
The Capi electronics shops airside and a Relay newsagent in the arrivals hall sell A1, Magenta, and Drei prepaid SIMs. It is convenient if you want a card in hand on arrival, but prices are full retail and you still go through the passport check, so expect a short wait after a long flight.
Supermarkets and Trafik Kiosks
Hofer (Aldi) sells the HoT SIM, and Trafik tobacconist-newsagents, Spar, and BILLA stock various prepaid starter packs and top-ups. This is the cheap, no-frills route, though for the budget supermarket SIMs you often complete the ID verification yourself online rather than at a counter.
Register, Activate, and Test
Wherever you buy, the card will not carry data until the photo-ID registration is done, so complete it before you walk off, then load a map to confirm you are online. A couple of minutes in the shop beats discovering an unregistered, dead SIM on the U-Bahn an hour later.
eSIM vs Local SIM Card in Austria
| Factor | eSIM | Local SIM |
|---|---|---|
| Setup time | 3 minutes (before your flight) | 10 to 20 minutes incl. passport registration |
| Registration | None | Mandatory passport/ID check (Austrian law) |
| Price (week of data) | ~8 to 18 USD (Nomad, Airalo, Holafly) | ~EUR 5 to 15 (often a full month, with calls) |
| Cross-border | Pick a Europe plan for the whole Alpine loop | EU roaming included, but Switzerland excluded |
| Best for | Most travellers, ready the moment you land | Longer stays or anyone wanting an Austrian number |
Austria is the rare place where the local SIM is genuinely cheaper for the data, since a full month of supermarket data can cost less than a week of travel eSIM. What tips the balance for short visits is the registration rule: every Austrian card means showing your passport and waiting for verification before it works, while an eSIM is pre-registered under the provider's account and live the instant you land at Vienna. The local SIM still wins if you want an Austrian phone number for calling guesthouses or ski-lift offices, or if you are staying long enough for the monthly value to beat the convenience.
Austria-Specific Tips
Practical Advice for Staying Connected in Austria
Choose A1 for the mountains: For Hallstatt, the ski resorts, or the Grossglockner High Alpine Road, A1 holds a signal where HoT and spusu fade. Even so, side valleys, road tunnels, and ground above 2,000 m can go dark on every network, so download offline maps and your lift or trail info before you head up.
Lean on EU roaming, but mind Switzerland: Any Austrian SIM works free across the EU, so a hop into Bavaria or South Tyrol costs nothing extra. Switzerland and Liechtenstein are outside the EU, so a Swiss leg of an Alpine loop may incur roaming charges unless your plan lists them.
Budget brands ride the big networks: HoT uses Magenta and spusu uses Drei, so you get major-network city coverage at supermarket prices, just without A1's Alpine edge.
Top-ups are easy: Recharge any prepaid SIM in the carrier app, at a Trafik kiosk, or at supermarket tills. Adding a data pack is simple if a few rainy indoor days push your usage up.
WiFi is widespread but patchy on the move: Cafes, the Wiener Linien stations, and museums offer free WiFi, but it disappears the moment you are on a Danube cruise or a mountain trail, which is exactly when navigation matters most.
Frequently Asked Questions
Do I need my passport to buy a SIM card in Austria?
Yes. Since a 2019 law, every prepaid SIM in Austria must be registered against photo ID before it activates, so you need your passport or national ID even for a cheap supermarket card. Provider shops do the registration for free, while partner shops like Hartlauer may charge up to EUR 10. The cheapest supermarket brands sometimes ask you to verify online with a photo of your ID and a selfie, which is easiest for EU citizens. A travel eSIM avoids the step entirely because it is pre-registered under the provider's account.
Which Austrian carrier is best if I am heading into the Alps?
A1, in most cases. It is rated first for overall coverage and has invested the most in mountain infrastructure, so it reaches resort villages, gondola bases, and pass viewpoints around Hallstatt, Kitzbuehel, St Anton, Zell am See, and the Grossglockner where the budget brands fade. Magenta and Drei are excellent in the cities, and their supermarket brands HoT and spusu are great value there, but for deep valleys and ski terrain A1 is the safer single choice.
How cheap are prepaid SIMs in Austria?
Very cheap by European standards. spusu on the Drei network starts near EUR 4.90 for a 2 GB monthly pack, HoT on Magenta is around EUR 5.90 a month at any Hofer supermarket, and Drei and Magenta own-brand prepaid runs from about EUR 8. A1, the Alpine coverage leader, starts higher at around EUR 9.90. All include EU free-roaming, and prices are honest with no significant airport markup to dodge.
Will my Austrian SIM work for free in neighbouring countries?
Within the EU, yes. EU free-roaming rules mean any Austrian prepaid SIM works at no extra cost in Germany, Italy, Slovenia, Slovakia, Hungary, and the Czech Republic, which is handy for an Alpine loop that crosses borders. The exception is Switzerland and Liechtenstein, which sit outside the EU, so a Swiss leg may attract roaming charges unless your specific plan covers it. For a multi-country trip, a Europe regional eSIM can be simpler than juggling one country's card.
Should I get an eSIM or a local SIM for Austria?
For most short trips, an eSIM is the easier path. It installs in minutes before you fly and is live the instant you land at Vienna, skipping Austria's mandatory passport-registration step entirely. A local SIM is genuinely cheaper for the data here, often a full month for the price of a week of eSIM, so it wins for longer stays or if you want an Austrian phone number for calling guesthouses, tour desks, or ski-lift offices.
