Digital sovereignty in Germany’s fourth mobile network

Focussing on the German market, 1&1 actively strengthens the country’s digital sovereignty. As the fourth mobile network operator, 1&1 has relied from the outset on cutting-edge technology without compromise, operating Europe’s first fully virtualized 5G mobile network based on the innovative Open RAN technology – independent of dominant vendors that typically provide closed, all-in-one systems. The 1&1 O-RAN is ready for future applications that require real-time speeds, fostering more competition and innovation in the German mobile landscape.

Gigabit speeds in fixed networks

With around 4 million broadband customers, 1&1 is one of Germany’s leading providers of VDSL/Vectoring and fiber-optic connections. The nationwide fiber-optic transport network of 1&1 Versatel is connected to regional networks of leading local carriers and Deutsche Telekom.

The quality of our fixed-line products has been consistently recognized with top rankings in renowned tests for many years, most recently in July 2025 by IMTEST and zafaco. Over 4 million measurements were conducted, analyzing the quality, performance, and stability of the internet connections of leading national and regional providers. 1&1 emerged as the test winner with the grade “Very Good” (1.31).
