Consumer Access

We offer our customers these internet access products as subscription contracts with fixed monthly fees (and variable, volume-based charges) and contractually fixed terms.

Broadband Connections

With our broadband products under the 1&1 brand (especially VDSL/vectoring and fiber-optic connections), we are one of Germany’s leading suppliers.

We use our own fiber-optic network (1&1 Versatel) and connect the “last mile” of VDSL/vectoring connections (FTTC = Fiber-to-the-Curb) mainly via the BNGs/Layer 2 infrastructure of Deutsche Telekom (or Layer 3 outside our own fiber-optic network). In the case of direct fiber-optic connections (FTTH = Fiber-to-the-Home), we connect the “last mile” via the FTTH home connections of leading city carriers and Deutsche Telekom. In the case of our business with ADSL connections (currently being phased out), we use further advance service providers.

Mobile Internet

United Internet is also one of the leading providers of mobile internet products in Germany.

Since the launch of mobile services on December 8, 2023, 1&1’s mobile communications network has been fully operational. Wherever 1&1 does not yet have sufficient mobile coverage during its years of network expansion, it uses national roaming. National roaming is a standard procedure used in the rollout of new mobile networks that enables customers to surf and make calls without interruption in areas not yet covered. This is achieved by automatically using the roaming partner’s antennas in these areas. 1&1's exclusive national roaming partnership with Vodafone was launched in August 2024. Advance services that were previously purchased from Telefónica are being gradually reduced. 

As of the beginning of 2024, its more than 12 million existing MVNO customers are being gradually migrated to the 1&1 mobile network.

Mobile internet products are marketed via the premium brand 1&1 as well as via discount brands, such as winSIM and sim.de.
