O2 Telefónica's network is a central component for a positive customer experience and customers' mobile freedom.
Whether it's phone calls with family, friends and business partners or the use of digital applications such as music and video streaming, social media and mobile gaming - Telefónica Deutschland's mobile network ensures reliable, high-performance networking in the everyday digital lives of millions of private and business customers. With around 28,000 locations spread across the whole of Germany, Telefónica Deutschland is able to provide the population with optimum mobile services. For example, Telefónica Deutschland reaches over 99 percent of the population with its fast 4G/LTE network. The 4G mobile communications standard enables all customers to use their digital applications on mobile devices such as smartphones at any time, even when they are on the move. In addition, O2 Telefónica is driving the expansion of the 5G mobile communications standard with massive investments: The company initially launched the 5G network in the five largest German cities of Berlin, Hamburg, Munich, Cologne and Frankfurt in October 2020. Currently, about 95 percent of the population already benefit from 5G (as of January 2024). By 2025, O2 Telefónica will provide the whole population throughout Germany with 5G. In doing so, O2 Telefónica is relying not only on the use of the powerful 3.6 GHz frequencies, but also on a mix of different and state-of-the-art technologies to further accelerate the rollout.
