An Austria-only stay and a journey continuing into Germany, Italy or Switzerland deserve different price checks. First see what your current mobile contract already includes. If you need a separate data line, Austria’s fixed plans are straightforward to compare; the regional premium is small enough to calculate before choosing.
Prices checked 10 October 2026.
Compare the same data allowance and validity
The fixed-data table uses total allowances with 30-day validity. Every figure is a public price in EUR. A larger allowance does not reset each day, and the price alone says nothing about reception.
| Provider | 5 GB / 30 days | 10 GB / 30 days | 20 GB / 30 days |
|---|---|---|---|
| Horizon | €2.90 | €5.61 | €11.05 |
| Airalo | €7.50 | €10.50 | €15.00 |
| Nomad | €11.11 | €12.44 | €16.89 |
| Saily | €6.99 | €9.99 | €13.99 |
At 10 GB / 30 days, Horizon costs €5.61; Saily lists €9.99, a difference of €4.38. Compare all the rows before choosing: these are dated quotes for the listed offers, not a ranking of every provider or every possible discount.
City breaks and mountain days need different preparation
For Vienna or Salzburg, accommodation Wi-Fi may handle larger downloads while the eSIM covers time out in the city. In the mountains, the first question is reception rather than how many gigabytes remain. Store route information and bookings offline before leaving a Wi-Fi connection.
Do not treat a country coverage list as a guarantee for every valley, tunnel or mountain accommodation. A larger data pool changes your usage budget, not the local network. If you plan to work while travelling, include hotspot use in the estimate and check the connection available where you will actually stay.
A modest premium for a multi-country route
Horizon’s Europe plan is €7.27 for 10 GB / 30 days. Austria alone is €5.61, a difference of €1.66. The checked regional list includes Austria, Germany, Italy and Switzerland, making it worth considering for a continuous trip through those stops.
The shared allowance does not refill at a border. If Austria is your only destination, the country plan keeps the purchase focused on that stay. If you already have coverage in some countries through your home contract, compare only the gaps you actually need to fill. Check your carrier’s terms for Switzerland separately rather than assuming they match its other European roaming terms.
Unlimited phone data and hotspot are different
Holafly publishes a 7-day unlimited plan at US$27.50 in its USD duration table. The same page specifies 1 GB per day for hotspot sharing. That can suit heavy use on the phone, but it is not unlimited laptop data. The allowance, duration and currency differ from the fixed EUR plans above, so no percentage saving is calculated against it.
Hotspot sharing is free on every Horizon plan.
A laptop or another device uses the purchased pool alongside the phone. Include photo backups, software updates and video meetings in your estimate. For an unlimited plan from another provider, read its current fair-use and hotspot terms before buying.
Horizon plans have no throttling.
Actual reception and speed still depend on the supported network, location, phone and congestion. This article does not contain route tests or speed measurements.
Check the phone before paying
Check device compatibility and that the phone is unlocked. Follow the installation guide over a stable internet connection before departure. Keep the eSIM installed while troubleshooting; deleting it is not a routine connection fix.
Validity does not start until your eSIM first connects to a supported mobile network at your destination.
Horizon’s listed plans are data-only. A data connection is different from a local phone number, ordinary calls or SMS. Your home carrier may still charge for calls, texts or data on its own line. Review both lines’ settings rather than assuming the travel plan changes your home contract.

Short answers
Does 30-day validity mean I must stay for 30 days?
No. It is the expiry window after service begins, not a minimum stay. Compare the shorter plan’s actual price before assuming it costs less, and allow for your arrival and departure dates.
Is 10 GB a daily allowance?
No. In this comparison, 10 GB is the total pool for the plan. Sharing it with another device does not create a second allowance. Check your own recent mobile-data use and leave room for travel days.
