Telefónica and NOS agree to develop defence communications after 5G test in Portugal

The operators signed a memorandum to explore secure networks and digital services. They tested 5G integration at REPMUS but announced no awarded contract or commercial rollout.

Telefónica and NOS Comunicações announced a bilateral agreement on October 20 to develop connectivity, secure communications and digital services for defence and security scenarios in Europe. The agreement was signed during REPMUS 2026 in Portugal, an exercise held from August 31 to September 25, according to NATO. The announcement came after the exercise. The memorandum opens a collaboration; it is not an awarded military contract. [1][2]

The operators say they integrated their 5G capabilities during REPMUS to test how different infrastructures could work together. Their release provides no performance measurements or resulting commercial service. NATO confirms the broader scope of the maritime exercise, but its account does not assess that specific integration. Dinheiro Vivo covered the agreement using the companies’ statements without separate technical verification. [1][2][3]

The planned work includes network interoperability, secure communications, edge computing, artificial intelligence and connectivity for autonomous platforms. Telefónica and NOS describe these as areas to explore; they set no launch date or expected revenue. The archive photograph shows a NOS building in Lisbon in 2016, not the REPMUS 5G test. [1]
