MEO is a telecommunications brand and service operating in Portugal, managed by MEO - Serviços de Comunicações e Multimédia, a subsidiary of Altice Portugal (formerly Portugal Telecom). The brand was established in 2007 following the division of PT Comunicações and PT Multimédia. MEO provides both mobile and fixed telecommunication services, utilising copper cables for its operations. The television service provided by MEO is served on the ADSL line.
In 2014, Telecomunicações Móveis Nacionais (TMN), Portugal's first and largest mobile network operator, was integrated into the MEO brand. This followed the acquisition of two of TMN's shareholders, Telefones de Lisboa e Porto (TLP) and Marconi Comunicações Internacionais, by Portugal Telecom in 1994 and 2002 respectively. The commercial launch of MEO's ADSL2+ service took place in June 2007, with the satellite service beginning in April 2008. In January 2014, MEO and TMN merged to form a single brand, MEO Serviços de Comunicações e Multimédia S.A.
