Austria is easy to stay connected in: Vienna, Salzburg and Innsbruck have strong 4G and 5G, and the ski resorts and lake towns are well covered. The gaps are on high mountain routes. And near the western border, phones can drift onto Swiss or Liechtenstein networks — which sit outside the EU.
Short answer: a 5–10GB Austria plan with 30-day validity suits most trips. If you are skiing or hiking near Switzerland or Liechtenstein, check that your plan covers them or keep your phone on an Austrian network.
What an Austria eSIM costs
At the time of writing (October 2026), Wanderly's Austria plans start at $2.99 for 1GB, with 5GB for 30 days around $5 and 10GB for 30 days around $8. The median across data-only Austria plans is about $0.80 per GB — well under the $1.43 median across 187 countries in the Wanderly eSIM Price Index.
Austria has 30-day validity even on small plans, so there is no need to gamble on a short bundle.
Do you need an eSIM with your phone plan?
EU plans roam in Austria at domestic rates, subject to fair use. UK plans usually charge a daily fee for Europe, and US and Canadian plans usually charge a day pass. See eSIM vs international plan.
The western-border trap
In Vorarlberg and parts of Tyrol, Swiss and Liechtenstein networks can be stronger than Austrian ones. Switzerland is outside the EU, and Liechtenstein is in the EEA but often billed separately. On a home plan that can mean extra charges; on an Austria-only eSIM it can mean no data. Set network selection to manual on an Austrian network, or use a plan that lists both.
