Best eSIM for Austria: Plans, Prices and How to Choose
July 27th, 2026
TL;DR
The cheapest Keep On Roaming plan for Austria is the Roam Like Home® Austria 1 GB 7 Days plan at £4.00. If you measure value by price per gigabyte, the Austria 100 GB 30 Days plan wins at £43.50, which works out at less than 44p per GB (the 50 GB 30 Days plan is a whisker behind at 45p per GB). If you would rather not count megabytes at all, unlimited data starts at £6.50 for 1 day. Every plan connects to the Drei Austria network, with 5G where available.
What to look for in a travel eSIM for Austria
Coverage that matches your itinerary. Whether you are staying in Vienna or heading up into the Alps, check which local network your eSIM uses. Keep On Roaming plans for Austria run on Drei Austria, with 2G, 3G, 4G and 5G support.
A plan that fits your trip, not the other way round. A weekend city break and a month of touring need very different amounts of data. Look for a provider with a spread of plan sizes and durations so you are not paying for data you will never use, or rationing it in your final days.
Easy top-ups. Plans do run out, especially if you lean on maps and video calls more than expected. With Keep On Roaming you can top up an existing eSIM with more data from your account dashboard, without installing a new eSIM.
Installation before you fly. The best time to sort out your connectivity is at home on your own Wi-Fi, not in an arrivals hall. You install your Keep On Roaming eSIM before you travel via a QR code, and it activates when you arrive in Austria and connect to the network.

A quick steer on choosing. For a light-use week of maps, messaging and the odd search, the 1 GB 7 Days plan at £4.00 covers the basics. For a typical one or two week holiday with photos, social media and navigation, the 10 GB 30 Days plan at £12.50 gives you plenty of headroom at £1.25 per GB. Heavy users get the strongest per-gigabyte pricing at the top end, with 50 GB at 45p per GB and 100 GB at under 44p per GB. And if your trip is short and intense, the unlimited plans (from £6.50 for 1 day up to £34.00 for 30 days) remove the need to think about data at all.
Frequently asked questions
Will my phone work with an eSIM?
You need a phone that supports eSIM and is unlocked from your home carrier. Most recent smartphones qualify. The quickest check is to look in your phone's settings for an option like "Add eSIM" or "Add mobile plan". If it is there, you are good to go.
When should I install my eSIM?
Before you travel. You install it via a QR code while you still have a reliable connection at home, and it activates when you arrive in Austria and connect to the network. That means you are online from the moment you land.
What happens when my data runs out?
You can top up your existing eSIM with more data from your account dashboard. There is no need to buy and install a new eSIM, so a top-up takes moments rather than a reinstall.
Will my phone number change?
No. Keep On Roaming plans are data-only, and your existing SIM, number, calls and texts keep working alongside the eSIM. Friends, family and your bank can still reach you on your usual number.
Can I make calls and send texts on the eSIM?
The plans are data-only, so the eSIM itself does not include calls or texts. In practice, most travellers make calls over data using apps, while regular calls and texts continue to work through your existing SIM.
Which network will I connect to in Austria?
Your eSIM connects to Drei Austria, with 2G, 3G, 4G and 5G support.
