Austria eSIM

Austria's networks are strong in Vienna, Salzburg and the ski villages, but eight countries touch its borders, and the main train link from Vienna Airport is cut short until the end of October 2027. An Austrian prepaid SIM also has to be registered with photo ID before it works, so the easiest Austria eSIM is one you install at home; if your SIM is from an EU country, it already roams here like at home.

What a week of data costs in Austria

Prices for 7 days of data, checked on 2–3 November 2026. Daily passes charge for each day you use the phone abroad, per phone.

For a family of four on Verizon, that's $336 for one week. O2 and T-Mobile customers may need nothing extra for a short trip, though 256 kbps is slow for maps and photos. A1's tourist eSIM is good value for a fortnight, if you're happy to register it with your passport first.

If your SIM is from the EU, it already roams like at home in Austria, as long as you spend more time at home than abroad. UK plans aren't part of that system any more, which is why the UK rows above carry charges.

Landing at Vienna, Salzburg or Innsbruck

Switch the kimsim line on as the plane taxis to the gate and turn on Data Roaming for that line only. If you still need to install, Vienna Airport has free Wi-Fi in all areas. Then go through passport control, collect your bags and walk out through customs with a working map.

Entry rules. Since 12 October 2025, the EU's Entry/Exit System records non-EU visitors' fingerprints and a photo at the Schengen border, and it has been fully in place since 10 April 2026. Expect a longer queue the first time. ETIAS, the €20 travel authorisation for visa-free visitors, is not in operation yet; the official site says the EU will announce the start date several months ahead. So don't pay any website that offers you an ETIAS today. British visitors can stay up to 90 days in any 180 across Schengen, and your passport must have been issued less than 10 years before you arrive and expire at least 3 months after you leave.

Vienna (VIE): the airport link is changed until late 2027. The S-Bahn line through central Vienna, between Praterstern and the Hauptbahnhof, is closed from 7 September 2026 to the end of October 2027, and the S-Bahn station at Wien Mitte is shut. So:

• Railjet and Intercity trains run non-stop to Wien Hauptbahnhof in about 15 minutes, every half hour. This is the quickest way in.
• The City Airport Train now runs as non-stop coaches from outside Terminal 3 to Wien Mitte (Marxergasse), taking 21 minutes, every 12 minutes from 7am to 7pm. The operator expects this to last until 31 October 2027.
• The S7 only runs between the airport and Wien St. Marx, where tram 18 takes you on.

Timetables can change during the works, so check the ÖBB app on your new data before you pick a platform. A Vienna 24-hour ticket covers the city's core zone only, so the airport stretch needs its own ticket.

Salzburg (SZG): the airport is 4 km from the centre. Trolleybus 10 reaches the old town in about 15 minutes and line 2 in about 23. Salzburg sits on the German border, so check your phone has joined an Austrian network.

Innsbruck (INN): bus F links the terminal with the city centre and the main station in around 20 minutes.

Networks and coverage

Austria has three mobile networks: A1, Magenta Telekom and Drei (shown as 3). A1, formerly mobilkom austria, belongs to América Móvil's A1 Telekom Austria Group. Magenta is what T-Mobile Austria became after merging with UPC Austria in 2019. Drei took over the old Orange Austria network in a deal that closed on 3 January 2013. The Austria plan uses A1 and 3, not Magenta, and your phone shows their names, not kimsim.

Antenna data from April 2025 put technical 5G coverage at about 96% of the population. That's people, not land: much of Austria is mountain. Expect gaps in narrow side valleys, on high trails, off-piste and in long road and rail tunnels.

Borders. Austria touches Germany, Czechia, Slovakia, Hungary, Slovenia, Italy, Switzerland and Liechtenstein. In Salzburg, the Tyrol, Vorarlberg and around Lake Constance, your phone can join a foreign network without you crossing anything. If that happens, choose A1 or 3 by hand. The networks your plan uses are listed above.

Vienna, the Alps and the regions

• Vienna: generally good coverage on the street. Old cellar bars and thick-walled palaces can be weak indoors, so step outside to load a map.
• Salzburg and the Salzkammergut: fine in Salzburg. Lakeside villages such as Hallstatt sit under steep mountainsides, where signal can weaken; save your train and boat times before a day trip.
• Innsbruck and the Tyrol: good in Innsbruck and the main valleys. Higher up, on lifts and in side valleys, it comes and goes.
• Ski resorts: villages, lifts and huts are generally covered, but don't rely on signal off-piste. The UK Foreign Office warns that off-piste skiing is very dangerous and can invalidate your travel insurance.
• Glaciers: the Kitzsteinhorn's "Top of Salzburg" is at 3,029 m. Don't count on data for anything important that high.
• The Grossglockner High Alpine Road: 48 km up to 2,571 m at the Edelweiss Spitze, open from early May to early November. It's now closed for winter until early May 2027. Download an offline map before you drive it.
• Kleinwalsertal: this valley in Vorarlberg is reached only by one road from Oberstdorf in Germany. On the drive in, your phone may sit on a German network, where an Austria plan has no data.

This is general guidance, not a coverage map.

Trains, day trips and driving

• ÖBB trains: book Railjet, Intercity and regional trains, plus many buses, trams and U-Bahn tickets, in the ÖBB app; the mobile ticket is what you show the inspector. Railjets and Cityjets have free Wi-Fi called "OEBB", but ÖBB says it depends on mobile coverage along the line. Save tickets offline before you board.
• Day trips: Bratislava is a short train ride from Vienna, and Munich is close to Salzburg. Both are other countries, so an Austria plan stops working there. Look at Slovakia, Germany, Hungary or Czechia, or the Europe plan.
• Driving: motorways need a vignette. The 1-day (€9.60) and 10-day (€12.80) digital vignettes bought online in the ASFINAG app or shop are valid straight away, but a 2-month or annual one bought online only starts on the 18th day. If you need the longer one straight away, buy it at a sales point, where it can be valid at once.

Apps worth having

• ÖBB for trains and many regional buses, with mobile tickets.
• WienMobil, Wiener Linien's app, sells Vienna transport tickets, which are only valid with your photo ID.
• Rides: Uber works in Vienna around the clock, including airport pickups, and Bolt runs rides there too. Set accounts up at home, because sign-up can send a code by text to your usual number.
• Maps: download offline areas for any valley, lake or mountain day.
• WhatsApp: many hotels, ski schools and guides message you there. Keep your WhatsApp number working abroad.

SIM and phone rules

Since 1 January 2019, every Austrian operator must identify customers who buy prepaid SIM services, under a change to the Telecommunications Act. You need a valid official photo ID such as a passport, ID card or driving licence, and you can register online, even from abroad over Wi-Fi, or in a shop. A1, for example, says its tourist eSIM only gets its data once it's registered.

A travel eSIM installed at home skips the registration and the shop. It's data only, so your home number stays in the phone for calls and texts.

Common mistakes

• Heading for the S7 to Wien Mitte. Until the end of October 2027, the S7 stops at St. Marx and the CAT is a coach. Take a Railjet to the Hauptbahnhof or the CAT coach to Wien Mitte.
• Leaving Data Roaming on for your home line. For non-EU SIMs, that's where daily charges start. Why roaming goes on for the kimsim line only
• Starting the plan on a change of planes. If you only connect in Vienna on the way to Eastern Europe, keep the kimsim line off, or its days can start. If your plan started early
• Day trips over the border. Bratislava, Munich, Lake Constance and Switzerland are outside an Austria plan. How regional plans work
• No way to call for help. 112 works in Austria, alongside 144 for an ambulance, 133 for the police and 122 for the fire service; 140 is the alpine emergency number. A data-only eSIM can't dial them, so keep your home line on for calls.

How we put this page together

We checked Austria's prepaid registration site, A1's tariff page, ÖBB, Wiener Linien, the airports' and the City Airport Train's own pages, carriers' roaming price pages, EU and UK government sites and the other sources noted above on 1–3 November 2026. Wiener Linien's, Innsbruck Airport's, AT&T's and T-Mobile's pages block automated checks, so we read those facts from the pages' search listings. We haven't measured speeds or coverage in Austria ourselves, so coverage notes are general guidance, not a map. kimsim sells the eSIMs on this page.
