1&1 currently has 27% coverage of German households, aims to achieve 40% by the end of 2027 with high-bandwidth low band frequencies or 30% without low-band frequencies
Assessment
At the end of 2025, 1&1 had around 2,000 active base stations (Q3 2025: 1,500), representing 25% coverage. Therefore, 27% coverage would mean that 1&1 has added only around 160 active base stations in 2026.
