Short trips
Holafly is the only major travel eSIM with genuinely unlimited full-speed data in Austria, from €25.50 for 7 days. Ubigi unlimited costs €19 for 7 days. The "unlimited" plans from Saily and aloSIM throttle after a daily cap of 1.5 to 5 GB.
Living in Austria
For an Austrian number with truly unlimited data, Drei up Unlimited+ costs €24.90 / month and Magenta €29.90 / month, both unthrottled. A resident plan works out cheaper than any travel eSIM beyond about two weeks. Every travel eSIM applies a fair-use policy, resident plans do not.

The best unlimited data eSIM in Austria is Holafly, because it is the only major travel eSIM with no daily full-speed cap. Its Austria plan runs unlimited under a fair-use policy from €25.50 for 7 days on the Drei network. Every other travel "unlimited" plan is really a large daily allowance: Saily gives 5 GB/day and aloSIM 1.5 GB/day before slowing down.
For a stay longer than about two weeks, a resident plan is cheaper and unthrottled: bob Flex Unlimited (€18.90/month), 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?
| Provider | Daily full-speed cap | Speed after cap | Real verdict |
|---|---|---|---|
| Saily | 5 GB/day | 1 Mbps | Large daily allowance, not truly unlimited |
| aloSIM | 1.5 GB/day | 512 kbps | Lowest cap and slowest throttle |
| Ubigi | Not published | Not published | Unverified fair-use limit |
| Holafly | None | No daily throttle | Genuinely unlimited (fair use) |
Fair-use caps fetched July 25 2026, verify at checkout. Ubigi does not publish its daily cap or throttle speed.
Most travel eSIMs sold as "unlimited" are really daily-capped plans. Saily gives 5 GB/day at full speed, then drops to 1 Mbps. aloSIM has the tightest limit at 1.5 GB/day, then slows to 512 kbps. At those reduced speeds you can still load maps, messaging, and SD video, but not smooth HD streaming or large uploads.
Only Holafly runs with no daily full-speed cap, and Ubigi does not publish its fair-use throttle at all, so its unlimited claim is unverified. If you stream video for hours or tether a laptop all day, a daily-capped plan will throttle you well before the day ends.
"Unlimited" usually means a daily cap, not truly uncapped
Can You Get Unlimited Hotspot or Tethering in Austria?
Not fully on a travel eSIM. Holafly caps hotspot sharing near 500 MB/day (verify at checkout), even though its normal data is unlimited. The daily-capped plans, Saily and aloSIM, let you tether, but the hotspot data comes out of the same daily pool, so a laptop can exhaust the day's allowance in an hour. For unlimited tethering, an Austrian resident plan is the better tool.
Drei up Unlimited+ (€24.90/month) and Magenta SIM Only S (€29.90/month) allow unlimited data with no dedicated hotspot cap, so you can tether a laptop or tablet all day on an Austrian number. bob Flex Unlimited (€18.90/month) on the A1 network is the cheapest of the three. Magenta also sells data-only unlimited via SURF-style plans for a router or tablet without a voice line.
Tethering a laptop all day? Skip the travel eSIM
Is a Resident Unlimited Plan Cheaper Than an Unlimited Travel eSIM?
| Plan | What you get | Price | Network | Notes |
|---|---|---|---|---|
| bob Flex Unlimited | Unlimited data + 5,000 min | €18.90/mo | A1 | No contract |
| Drei up Unlimited+ | Unlimited 5G + unlimited min | €24.90/mo | Drei | eSIM |
| Magenta SIM Only S | Unlimited data | €29.90/mo | Magenta | Unthrottled; data-only SURF plans too |
| yesss SIMple XL 5G | 200 GB (largest capped bundle) | €19.99/mo | A1 | Capped, not unlimited |
| Holafly (30 days) | Unlimited travel eSIM | €68.90 | Drei | No Austrian number, no ID needed |
Prices as of July 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 €68.90, while bob (€18.90), 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.

Unlimited Data eSIM in Austria: Frequently Asked Questions
Is Holafly really unlimited?
Yes, within a fair-use policy. Holafly is the only major travel eSIM with no daily full-speed cap, so you can stream and browse without a gigabyte counter. Its Austria plan runs on the Drei network and costs €11.37 for 3 days, €25.50 for 7 days, and €68.90 for 30 days. The one real limit is hotspot sharing, capped near 500 MB/day (verify at checkout).
What speed do you get after the fair-use cap?
It depends on the provider. Saily drops to 1 Mbps once you pass its 5 GB/day cap. aloSIM slows to 512 kbps after 1.5 GB/day. 1 Mbps is enough for maps, messaging, and SD video, but not smooth HD streaming. Holafly has no daily throttle, and Ubigi does not publish its throttle speed (unverified).
Which unlimited eSIMs throttle after a daily cap?
Saily throttles after 5 GB/day and aloSIM after 1.5 GB/day, each dropping to 1 Mbps or slower. These plans are marketed as unlimited but are really large daily allowances. Holafly has no daily full-speed cap. Ubigi does not publish a daily cap, so its fair-use limit is unverified until checkout.
Can you use unlimited eSIM data as a hotspot in Austria?
Only within limits. Holafly caps hotspot sharing near 500 MB/day (verify at checkout), and daily-capped eSIMs like Saily and aloSIM share tethering from the same daily pool. For heavy tethering, an Austrian resident plan is better: Drei up Unlimited+ (€24.90/month) and Magenta SIM Only S (€29.90/month) allow unlimited data with an Austrian number.
Is a resident unlimited plan cheaper than a travel eSIM?
For stays over about two weeks, yes. bob Flex Unlimited costs €18.90/month, Drei up Unlimited+ €24.90/month, and Magenta SIM Only S €29.90/month, all with an Austrian number and no daily throttle. Holafly unlimited for 30 days is €68.90. Resident plans need passport ID and sometimes a Meldezettel, so travel eSIMs still win for short trips.
