Plan for your trip: Austria · Data for your trip — See plans →

Getting mobile data in Austria works the same as elsewhere in the EU: a travel eSIM installed at home, or a local SIM that has to be registered with an ID document. In Vienna, Salzburg and Innsbruck, the mobile network is solid. In the Alps, coverage depends on the terrain: in valleys, on mountain passes and in tunnels, the signal can drop.

How does mobile data work in Vienna and other Austrian cities?

Mobile data in Vienna covers the whole city, including the U-Bahn, where there’s usually signal at stations and in most tunnels. Austria’s major carriers, A1, Magenta and Drei, run 4G and 5G networks, and a travel eSIM connects to one of them as a partner network. Which network you get depends on the plan and your phone model.

In Salzburg, Graz, Linz and Innsbruck, coverage in the center and the suburbs is solid too. Slowdowns happen at Christmas markets, concerts and train stations at rush hour; that’s network congestion, not a problem with your profile. Free Wi-Fi is available in many cafés and on some trains.

Is there signal in the Austrian Alps, on the slopes and in tunnels?

Coverage in the Austrian Alps is good where people live and ski, and weakens where the mountains block the cell towers. In the villages of Tyrol, Vorarlberg and Salzburg state, at the lifts and in hotels, you’ll usually have signal. At the top lift stations the signal is often decent thanks to line of sight, but in narrow side valleys and on trails beyond a pass it can disappear.

Local SIM card or eSIM in Austria?

For data on a trip around Austria, a travel eSIM is the easier choice, while a local SIM makes sense for a long stay. Since 2019, local prepaid SIM cards in Austria have to be registered with an ID document, and as of October 2026 the rule still applies. You register in store or online, and the process differs between carriers, so check it before your trip. A local SIM gives you an Austrian number.

A travel eSIM skips local registration. With MoreSim, you buy on the website or in the Telegram bot @moresim_bot, and the QR code arrives in the chat in about 30 seconds. The profile works as a second line, and your home SIM stays in the phone. The plan starts counting from its first connection to a network in your destination country, so install it at home over Wi-Fi. MoreSim plans are mobile data only, with no phone number: you call through messaging apps, and bank texts keep coming to your home SIM. Data amounts and validity for Austria are on the country’s catalog page.

1. Check that your phone supports eSIM; the bot does this automatically.
2. Buy a plan for Austria or the region and install the profile at home over Wi-Fi.
3. After landing, turn off airplane mode and pick the eSIM for cellular data.
4. Turn on data roaming for the eSIM: most travel eSIMs connect to a local carrier’s network as roaming SIMs, so without it you won’t get data. Turn off cellular data on your home SIM so your data doesn’t go through your home carrier.
5. If the network doesn’t show up, toggle airplane mode or select a network manually in Settings.

Is Austria included in a Europe eSIM plan?

Austria is in the EU, and European regional plans usually include it. But check the exact country list for the MoreSim Europe plan on the plan card in the catalog or in the bot: every plan has its own list, and it changes over time. Check every country on your route, not just Austria.

The EU “roam like at home” rule applies to SIM cards from EU carriers: a local Austrian SIM usually works in Germany or Italy on home terms, subject to fair use limits. Switzerland is not in the EU, so the rule doesn’t apply there. If your route goes through Switzerland, check it separately on your plan’s country list.

How do you stay connected on trains from Austria to its neighbors?

On trains from Austria to neighboring countries, you’ll generally have coverage along lowland lines, while mountain sections and tunnels have gaps. Trains link Vienna with Budapest, Prague, Munich and Bratislava, and Innsbruck and Salzburg with Germany, Italy and Switzerland. At the border, your phone switches to the neighboring country’s network, so every country on your route needs to be in your plan.

If a country on your route isn’t in your plan, install a separate plan for it as a second profile at home, in advance. On the train, after the border, you just pick the right eSIM for mobile data.

How much data do you need in Austria?

A week in Vienna or Salzburg usually fits into 3–5 GB, since maps, messaging, tickets and finding restaurants don’t use much. A ski week uses more because of videos from the slopes, video calls and social media. What eats the most data is video clips, streaming and automatic photo backup to the cloud.

• Download offline maps of the cities and your ski area before the trip.
• Keep photo and video uploads to the cloud on hotel Wi-Fi.
• Turn off automatic app updates over mobile data.
• If you run out, top up without a new eSIM: use “Top up data” on the eSIM card in your account or in the bot’s app, if top-ups are available for that plan.
