Drei SIM Card

Drei (Three) is a prominent telecommunications brand operating in Austria, serving as part of the global Three brand family owned by CK Hutchison Holdings. The brand provides mobile communication, internet, and digital services. While the brand is heavily associated with Austrian mobile infrastructure, the physical SIM cards used for the service are electronic components typically manufactured by global technology partners such as Giesecke+Devrient, Thales, or IDEMIA, primarily in specialized facilities located in Europe and Asia.

The 'Three' brand originated in Hong Kong under the conglomerate CK Hutchison and was launched as a 3G-focused mobile operator in the early 2000s. In Austria, the brand operates as Hutchison Drei Austria GmbH. The ultimate ownership lies with the CK Hutchison group, headquartered in Hong Kong, which manages an extensive portfolio of international ports, retail, infrastructure, and telecommunications businesses.
