Best Unlimited Data eSIM in Austria (2026)

What Is the Best Unlimited Data eSIM in Austria?

Prices as of July 2026, verify at checkout. Prices are in the currency each provider bills; US-dollar prices are not converted. Fair-use caps fetched July 25 2026; Ubigi and Holafly re-checked October 1 2026.

The best unlimited data eSIM in Austria is Holafly, because it publishes no daily full-speed cap. Holafly's Austria plan runs unlimited under a fair-use policy from US$27.50 for 7 days on the Drei network. Most other travel "unlimited" plans are really large daily allowances: Saily gives 5 GB/day and aloSIM 1.5 GB/day before slowing down. Maya Mobile markets no throttling, but its own terms mention a daily quota without a number.

For a stay longer than about two weeks, a resident plan is cheaper and unthrottled: Drei up Under27 unlimited (€14.90/month) for under-27s, Drei up Unlimited+ (€24.90/month), and Magenta SIM Only S (€29.90/month) all give truly unlimited data with an Austrian number. The Austrian telecom regulator RTR supervises these resident plans, and its netztest.at tool measures real speeds; travel eSIMs sold abroad are not covered by the TKG 2021 minimum-speed reduction right.

Which "Unlimited" eSIMs Actually Throttle You?

How much full-speed data each "unlimited" eSIM really gives. Ubigi and Holafly from our catalog, re-checked October 1 2026; all other rows from the provider sites in the month shown. US-dollar prices are shown as billed, not converted. Verify on the provider site.

Most travel eSIMs sold as "unlimited" are daily-capped plans. Saily and Firsty give the most at 5 GB/day, then Saily drops to 1 Mbps and Firsty to 512 kbit/s. aloSIM has the tightest cap: 1.5 GB/day, then 512 kbit/s. Ubigi caps per plan instead, 20 GB on 7 days, but keeps the fastest fallback at 2 Mbps. Holafly and Maya Mobile publish no daily figure at all.

A missing number is not the same as no limit. Holafly applies a fair-use clause and caps hotspot use at 1 GB/day; one test report saw throttling after about 90 GB a month, a test value, not an official figure. Maya Mobile markets "no throttling", yet its own terms mention a daily high-speed quota without a number. At 1 Mbps or less you can still use maps, messaging and SD video, but not smooth HD streaming or large uploads.

Can You Get Unlimited Hotspot or Tethering in Austria?

Is a Resident Unlimited Plan Cheaper Than an Unlimited Travel eSIM?

Prices as of July 2026 (Drei Under27 re-checked October 2026), verify at checkout. Resident plans require passport ID; contract eSIMs may require a Meldezettel.

Over a full month, a resident plan wins easily. Holafly's 30-day unlimited is US$76.50, while Drei up Under27 (€14.90), Drei up (€24.90), and Magenta (€29.90) all cost far less per month and add an Austrian number plus unthrottled tethering. The break-even is roughly one week: past about 7 days, even the cheapest resident plan beats a rolling Holafly pass.

Travel eSIMs still win for short trips and for anyone without Austrian ID. Resident plans need passport verification and contract eSIMs may need a Meldezettel, which a visitor will not have. If you only need a huge but capped bundle rather than true unlimited, yesss SIMple XL 5G gives 200 GB for €19.99/month, the largest capped bundle on the market.

How Much Does Unlimited Data Cost in Austria?

Prices as of July 2026, verify at checkout. Prices are in the currency each provider bills; US-dollar prices are not converted.

Unlimited travel eSIMs for Austria cost €19 to €44 at Ubigi; Holafly prices its 3- to 30-day plans in US dollars. Holafly spans €3.90 (1 day) to US$76.50 (30 days). Ubigi is the cheapest for a week at €19. The daily-capped plans, Saily and aloSIM, bill in US dollars: US$23.00 to US$48.99 for their unlimited tiers, and their fixed-GB bundles are cheaper still.

For anything longer than about two weeks, a monthly resident plan undercuts every travel eSIM: Drei up Under27 (€14.90) for under-27s, Drei up (€24.90), and Magenta (€29.90) per month, each with an Austrian number. Compare all plans on our mobile plans price comparison.
