NOS Portugal Telecommunications

NOS is a leading Portuguese telecommunications and media group, providing a wide array of services including mobile and fixed telephony, broadband internet, cable television, and cinema distribution. The brand was formed through the historic merger of two major Portuguese telecom entities, ZON Multimédia and Optimus Telecomunicações, which unified their infrastructure and customer bases to create a stronger competitor in the Iberian market.

While the company provides digital services rather than physical manufactured goods, its physical infrastructure—including fiber optic networks, 5G towers, and data centers—is located primarily across Portugal. The brand is deeply rooted in the Portuguese economy and serves as a primary provider of digital entertainment and connectivity for millions of residents and businesses.

Ownership of NOS is structured through a major holding company involving Sonae and other investors. It is managed as a public limited company listed on the Euronext Lisbon stock exchange. The brand continues to lead the Portuguese market in innovation, particularly within the rollout of next-generation 5G networks and the management of large-scale cinema operations through its subsidiary, NOS Cinemas.
