Drei is the Austrian mobile network operator of the Hutchison group. It sells mobile telephony and mobile internet under the Drei brand and, for consumers, telephony, internet and TV products. Its business offer ranges from tariffs for small businesses and self-employed people to private networks, IoT and mobile device management. It also sells wholesale services such as MVNO access. The services are delivered as network connectivity and managed telecom contracts rather than as software that the customer runs.
Hutchison Drei Austria GmbH is registered in Vienna and is wholly owned by Hutchison Drei Austria Holdings GmbH. This is a subsidiary of CK Hutchison Holdings in Hong Kong. Because the ultimate parent sits outside the EU, the ownership question matters for jurisdiction and control for European organisations. The public pages do not state where customer data is hosted, so customers with sensitive traffic should ask for hosting locations and data-transfer terms before contracting.
