Updated July 25 2026. **Holafly** is the only major travel eSIM with genuinely unlimited full-speed data in Austria, from **EUR 25.50 for 7 days**, while **Ubigi** unlimited (**EUR 19 for 7 days**) and the "unlimited" plans from **Saily**, **Nomad**, and **aloSIM** actually **throttle after a daily cap of 1.5 to 5 GB**. For residents who want an Austrian number, **Drei up Unlimited+** (**EUR 24.90/month**) and **Magenta** (**EUR 29.90/month**) give truly unlimited data. Every travel eSIM applies a fair-use policy.

| Provider | Plan | Price | Full-speed cap | Throttle after cap | Hotspot cap |

| Holafly | Unlimited, 7 days | EUR 25.50 | **Unlimited** (fair use) | No daily throttle | ~500 MB/day (verify at checkout) |
| Ubigi | Unlimited, 7 days | EUR 19 | Not published (unverified) | Not published | Not published |
| Nomad | Unlimited, 7 days | EUR 21.98 | **2 GB/day** | Then **1 Mbps** | From the 2 GB/day pool |

| aloSIM | Unlimited*, 10 days | EUR 21.16 (conv.) | **1.5 GB/day** | Then **512 kbps** | From the 1.5 GB/day pool |

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](https://www.rtr.at) supervises these resident plans, and its [netztest.at](https://www.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

Read the fine print before you buy. **Saily (5 GB/day)**, **Nomad (2 GB/day)**, and **aloSIM (1.5 GB/day)** all market plans as unlimited but slow you to **1 Mbps** or **512 kbps** once you pass the daily cap. **Holafly** is the only travel eSIM with no daily throttle, and **Ubigi** does not publish its cap (unverified). For genuinely unthrottled data, choose Holafly or an Austrian resident plan.

## 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

If your main use is **tethering** a laptop for remote work, avoid Holafly's **500 MB/day** hotspot cap and the daily-capped travel plans. Pick **Drei up Unlimited+** or **Magenta** for uncapped tethering, or see our [eSIM guide for digital nomads](/communication/esim-for-digital-nomads).

## 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](/living/vienna-registration), 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.
