## What Is the Best Unlimited Data eSIM in Austria?

| Provider | Plan | Price | Full-speed cap | Throttle after cap | Hotspot cap |
| --- | --- | --- | --- | --- | --- |
| Holafly | Unlimited, 7 days | €25.50 | **Unlimited** (fair use) | No daily throttle | ~500 MB/day (verify at checkout) |
| Ubigi | Unlimited, 7 days | €19 | Not published (unverified) | Not published | Not published |
| Saily | Unlimited, 15 days | €45.07 (conv.) | **5 GB/day** | Then **1 Mbps** | From the 5 GB/day pool |
| aloSIM | Unlimited*, 10 days | €21.16 (conv.) | **1.5 GB/day** | Then **512 kbps** | From the 1.5 GB/day pool |
Prices as of July 2026, verify at checkout. USD prices converted at 0.92 EUR/USD where marked (conv.). Fair-use caps fetched July 25 2026; Ubigi does not publish a daily cap.

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](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 |
| 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

Read the fine print before you buy. **Saily (5 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** 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

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 | €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](/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 €19.99/month**, the largest capped bundle on the market.

Unlimited travel eSIMs for Austria run from about **€11 to €69**. **Holafly** spans **€11.37 (3 days)** to **€68.90 (30 days)**. **Ubigi** is the cheapest for a week at **€19**. The daily-capped plans, **Saily** and **aloSIM**, sit around **€21 to €45** 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: **bob (€18.90)**, **Drei up (€24.90)**, and **Magenta** (€29.90) per month, each with an **Austrian number**. Compare all plans on our [mobile plans price comparison](/communication/mobile-plans).

## 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.

### How much does an unlimited data eSIM cost in Austria?

Travel eSIMs run from about **€11 to €69**. **Holafly** spans **€11.37 (3 days)** to **€68.90 (30 days)**, **Ubigi** is **€19 for 7 days** and **€44 for 30 days**, and daily-capped plans from **Saily** and **aloSIM** sit around **€21 to €45**. Resident unlimited plans cost **€18.90 to €29.90** per month.
