A1 Telekom Austria: sovereignty score and 8 European alternatives

A1 Telekom Austria is a telecommunications operator headquartered in Vienna. Its portfolio includes fixed-line and mobile telephony, internet and IPTV, IT services, wholesale services and mobile payment services. Services are provided over its own networks and through subscription contracts, mainly for customers in Austria, and the group is active in several European markets.

A1 Telekom Austria AG is a subsidiary of A1 Telekom Austria Group, the European unit of América Móvil. That group is majority-owned by América Móvil, which is headquartered in Mexico City. For a European organisation, this non-European ownership is a relevant point when assessing jurisdiction and access to data. As an Austrian operator, A1 is subject to EU and Austrian data protection law. Questions about data storage and business telephony should be put directly to the provider. The company is not open source.
