Our verdict
A1 Telekom Austria is a carrier roaming option rather than a travel eSIM, which suits subscribers who want one home bill and known networks in 137 countries. The trade-off is cost, since data is metered and priced per GB rather than sold as a flat travel eSIM.

- Short trips and long trips alike, with top-ups for journeys that overrun the plan
Who should look elsewhere
- Anyone who needs unlimited data, since it is not offered here
- Buyers who want a pre-bought travel eSIM, where eSIMGo.is starts at $0.99

What data costs
Roaming starts at €4.90, and the headline rate is €2 per GB. Reference prices sit at the same level for the US, UK, Thailand, Turkey and Mexico, with Japan higher. Travel inside the EU is included in the home plan, while Switzerland and the global Roaming Pass carry their own rates.
Who runs it
The operator is A1 Telekom Austria AG, based in Austria and founded in 1996. As an established carrier, roaming bills onto the home contract, so account help comes from the same company. Support runs through email, chat and phone, with a help centre for self service questions and live channels for urgent ones.

Frequently asked questions
What does roaming data cost?+
Data starts at €4.90, with a headline rate of €2 per GB. Reference prices sit at the same level for the US, UK, Thailand, Turkey and Mexico, and Japan is higher. Travel inside the EU is included in the home plan, while Switzerland and the global Roaming Pass are billed separately.
How many countries are covered?+
Coverage runs to 137 countries, with partner networks named in the US, UK, Japan, Turkey, Thailand, Mexico, Switzerland, Brazil, India, Australia and China. Recognisable hosts include AT&T in the US, Vodafone in the UK and DoCoMo in Japan, so you land on a known network.
Is the data unlimited?+
Unlimited data is not offered, so plans run on metered data or a Roaming Pass bundle. The global Roaming Pass bills by the gigabyte at €2, so heavy streaming abroad lands on the bill, and pass data stops at a default spend limit.
Can I use it while living abroad?+
The fair use policy rules out permanent EU roaming: surcharges apply when most minutes, messages or data are used abroad and the SIM stays registered abroad across several billing periods. A global Roaming Pass is built for trips, so a long stay in one EU country is a poor fit.
How do I get help while travelling?+
Help runs through email, chat and phone, so a traveller can call, chat or email without a reseller in between. A1 Telekom Austria AG is the legal entity behind the service and is based in Austria, so account questions go to the carrier itself.
Do I need a new eSIM to use this?+
No new profile is needed. A1 Telekom Austria is sold as a carrier plan, so roaming goes onto the SIM you already hold and stays on the home bill. Listed features are 5g and carrier plan, and access rides on named partner networks such as AT&T or DoCoMo.
What do destination bundles cost?+
Bundles are priced by destination: €49 for the US, €59 for Japan and €49 for the European allowance, so Japan comes out the costliest of the three. A smaller starter amount is listed from €4.90.
