Telefónica's mobile brand Movistar has launched its Standalone 5G network in Spain.
The operator has called the service 5G+, and worked with both Nokia and Ericsson to launch the service.
The service has been launched in Madrid, Barcelona, Malaga, Seville, Palma de Mallorca, Las Palmas de Gran Canaria, Avila, Segovia, Castellón, El Ferrol, and Vigo, covering more than 700 municipalities.
Standalone 5G is seen by many in the telecoms industry as true 5G, as it is not reliant on older mobile generations and solely uses a 5G core network.
Non-Standalone 5G is the first implementation of the 5G network architecture and designed to be deployed on top of an existing 4G LTE network.
Movistar plans to roll out the service to most of the cities with a population of more than 250,000 people across the country by the end of the year.
The operator's Non-Standalone 5G service uses the 3.5GHz and 700MHz bands and currently provides coverage to more than 85 percent of the population.
In the UK, Vodafone launched its own Standalone 5G service last month. Dubbed 'Ultra 5G', the service has been initially switched on in London, Manchester, Glasgow, and Cardiff.
