Will the eSIM work on the Grossglockner road?

Partly. The lower approaches have signal, but the high pass and glacier viewpoints run through dead zones. Download the route, tolls and parking details beforehand, and expect intermittent data at altitude.

Does a Carinthia eSIM cover crossing into Italy or Slovenia?

No. It is an Austria plan, so data works throughout Austria but not once you cross into nearby Italy or Slovenia. Within Carinthia you roam on A1, Magenta or Drei automatically.

Good to know in Carinthia

Carinthia's lakes are warm enough to swim from June, but the Grossglockner and Nockalm mountain roads run through long dead zones. Screenshot toll info, viewpoints and your onward route before you drive up, as signal vanishes for stretches at altitude.

Best time to visit Carinthia

June to September is peak Carinthia, when the lakes warm to Austria's most swimmable temperatures for bathing, boating and lakeside stays; winter opens Nassfeld and Bad Kleinkirchheim for skiing.

Two simple ways to buy

Every Carinthia eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Carinthia — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Carinthia eSIM: your local data guide.

Carinthia is Austria's lake district, where the warm Wörthersee, Millstätter See and Faaker See sit below the Karawanken and the Grossglockner. From Klagenfurt and lively Velden to the Nassfeld pistes and the Grossglockner High Alpine Road, a Carinthia eSIM keeps lake-cruise times, ski apps and mountain-road maps live. Lakeshores stay connected; high passes and glaciers do not.

One eSIM for Carinthia and all of Austria. It's the national Austria eSIM — from $2.15/day with unlimited data, working the same in Carinthia as it does the moment you leave it.

Landing at Klagenfurt (KLU)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
