Telefónica

Telefónica is one of the world's largest telecommunications operators, with roots in a company founded in 1924, originally as Compañía Telefónica Nacional de España, to unify Spain's fragmented telephone infrastructure. More than a century later it serves millions of customers across Europe and Latin America and is headquartered in Madrid, Spain. Its business has broadened from telephony into connectivity and integrated digital technology solutions, spanning 5G networks, cybersecurity, cloud computing, Internet of Things and artificial intelligence services for consumers and businesses.

The company operates in heavily regulated markets across multiple jurisdictions in Europe and Latin America, and its work touches data protection, competition, spectrum and communications regulation, technology contracting and cross-border commercial arrangements. Its operating footprint extends from Spain and Madrid to the wider European and Latin American markets in which it provides connectivity and digital services.

Telefónica's technical domains include telecommunications, 5G networks, cybersecurity, cloud computing, IoT, artificial intelligence and digital transformation. The company describes a culture of continuous reinvention, evolving alongside technological advancement, founded on the belief that connecting people through reliable communication was essential for national progress and social cohesion rather than simply a business opportunity.
