What is an eSIM, and how does it work in Austria?
An eSIM (embedded SIM) is a digital SIM card built into your phone, tablet, or laptop. Instead of slotting in a physical card, you download a network profile from a provider, which connects you to a local mobile network. For Austria, that means you can buy a plan at home, install it in minutes, and arrive already online.
When you buy an eSIM plan the provider sends a QR code or an in-app install link. Scanning it loads the profile onto your device, and from then on the eSIM behaves just like a normal SIM for data. You can keep your usual SIM active at the same time, so your home number still works for calls and texts.
Is an eSIM better than a prepaid SIM card in Austria?
For most travellers, yes. A local prepaid SIM in Austria means finding a shop, showing ID, and setting it up, while a travel eSIM installs before you fly and activates the moment you land. You keep your home number on your normal SIM for calls and codes, and use the eSIM for data. For a short city break or a longer Alps trip, an eSIM is usually the faster and simpler option.
Mobile networks and coverage in Austria
Austria's main mobile networks are A1, Magenta, and Drei. All three offer strong 4G and widespread 5G across Vienna, Salzburg, Graz, and Innsbruck, with excellent coverage along the main valleys, train lines, and motorways. Travel eSIMs connect through these local networks, so you get the same everyday coverage as an Austrian SIM.
Ubigi connects to Austria's networks for fast, steady data across the country, while Holafly runs on the same local infrastructure with unlimited data plans. Coverage is excellent in Vienna, Salzburg, and the main towns, and stays reliable across the ski resorts and along the rail routes, though signal can dip deep in remote high-Alpine valleys.

How to choose the right eSIM for Austria
A few quick checks make it easy to pick the right plan before you travel:
Check your data needs: For maps, messaging, and browsing a small plan is usually enough. For video calls, remote work, or streaming, choose a larger or unlimited plan.
Match your trip length: Short Vienna city breaks suit small one-off bundles, while longer Alps trips or remote work are better with bigger plans or unlimited data.
Touring more of Europe? If Austria is part of a wider Europe trip, look for a regional or multi-country plan so one eSIM covers several countries.
Verify device compatibility: Most recent iPhones, Google Pixels, and Samsung Galaxy phones support eSIM. Check under Settings, then Mobile Network, then Add eSIM.
Customer support and setup help
Both providers offer support to get you online quickly. Ubigi has an in-app help centre and email support, plus clear install guides for iOS and Android. Holafly offers 24/7 multilingual chat support and a step-by-step setup flow, which is reassuring if it is your first time using an eSIM. Whichever you choose, install and test the eSIM before you fly so you land already connected.
How to set up your eSIM in Austria
Setting up your eSIM for Austria takes just a few minutes:
1. Check compatibility: Confirm your phone supports eSIM (most recent models do). Ubigi and Holafly both list supported devices on their sites.
2. Choose your plan: Pick a data size and validity that matches your trip.
3. Install the eSIM: After purchase you receive a QR code or in-app link. Scan or tap to load the profile onto your device.
4. Activate on arrival: Turn on your eSIM line and enable data roaming when you land in Austria. Activation usually starts automatically.
5. Test your connection: Open a map or browser to confirm data is working. If not, restart your phone or toggle airplane mode.
