Nos
Portuguese telecommunications operator
Last updated August 31, 2026
History
NOS was established in 2013 when ZON Multimédia and Optimus Telecomunicações merged. The transaction combined two complementary parts of Portugal’s communications economy. ZON brought capabilities associated with cable television, fixed communications, media and cinema, while Optimus contributed a mobile telecommunications business. The resulting group adopted the NOS name and pursued an integrated communications model rather than operating as a narrowly defined mobile or television company. The group’s service portfolio covers mobile communications, fixed-line telephony, broadband access and television. Its consumer proposition is built around standalone services as well as bundled packages, allowing customers to combine internet, television, telephone and mobile products. The company’s current public materials specifically promote access to 5G through mobile tariffs, fixed and mobile internet, television, telephone services, smartphones and home alarms. Online retail and service channels form part of the customer interface for these offerings. The merger also gave NOS a continuing connection to Portugal’s media and entertainment landscape. Television services are represented by the NOS TV offering, while the company’s corporate heritage includes the media and cinema activities associated with ZON. The available source material does not provide enough detail to document the full evolution of individual channels, production businesses, acquisitions or distribution agreements, so those aspects are not expanded here. NOS remains focused on the Portuguese market and is publicly listed on Euronext Lisbon. Its present brand proposition centers on connectivity and convergence: mobile access, broadband, television and other household services are presented as parts of one communications relationship. Beyond these established areas, the supplied references do not reliably identify current senior executives, ownership structure, financial results, major controversies, campaigns or material strategic transactions. Such information has not been added without supporting sources.
