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 EUR 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, Nomad 2 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 (EUR 18.90/month), Drei up Unlimited+ (EUR 24.90/month), and Magenta SIM Only S (EUR 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 |
| Nomad | 2 GB/day | 1 Mbps | Fine for light days, throttled for streaming |
| 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. Nomad gives 2 GB/day before the same 1 Mbps throttle. 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, Nomad, 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+ (EUR 24.90/month) and Magenta SIM Only S (EUR 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 (EUR 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 | EUR 18.90/mo | A1 | No contract |
| Drei up Unlimited+ | Unlimited 5G + unlimited min | EUR 24.90/mo | Drei | eSIM |
| Magenta SIM Only S | Unlimited data | EUR 29.90/mo | Magenta | Unthrottled; data-only SURF plans too |
| yesss SIMple XL 5G | 200 GB (largest capped bundle) | EUR 19.99/mo | A1 | Capped, not unlimited |
| Holafly (30 days) | Unlimited travel eSIM | EUR 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 EUR 68.90, while bob (EUR 18.90), Drei up (EUR 24.90), and Magenta (EUR 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 EUR 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 EUR 11.37 for 3 days, EUR 25.50 for 7 days, and EUR 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. Nomad and Saily drop to 1 Mbps once you pass their daily cap (2 GB/day for Nomad, 5 GB/day for Saily). 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, Nomad after 2 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, Nomad, and aloSIM share tethering from the same daily pool. For heavy tethering, an Austrian resident plan is better: Drei up Unlimited+ (EUR 24.90/month) and Magenta SIM Only S (EUR 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 EUR 18.90/month, Drei up Unlimited+ EUR 24.90/month, and Magenta SIM Only S EUR 29.90/month, all with an Austrian number and no daily throttle. Holafly unlimited for 30 days is EUR 68.90. Resident plans need passport ID and sometimes a Meldezettel, so travel eSIMs still win for short trips.
How much does an unlimited data eSIM cost in Austria?
Travel eSIMs run from about EUR 11 to EUR 69. Holafly spans EUR 11.37 (3 days) to EUR 68.90 (30 days), Ubigi is EUR 19 for 7 days and EUR 44 for 30 days, and daily-capped plans from Nomad, Saily, and aloSIM sit around EUR 21 to EUR 45. Resident unlimited plans cost EUR 18.90 to EUR 29.90 per month.
