Some specific information for our English speaking custumers

Television Receiving Systems

With a satellite television installation it is possible to receive a lot of national (German) and international channels (for some examples see below). Many of the channels are free to view. For the pay-per-view channels you additionally need a subscription.




Cable television is relatively easy to connect to, requiring only a digital receiver and a subscription agreement. There are about 40 channels on the cable (depending on where you're located). Most of them broadcast in German, but you usually get the likes of CNN, CNBC, MTV and BBC World. The difference between cable television and terrestrial (DVB-T) or satellite television (DVB-S) is that cable usually involves a connection fee as well as a monthly subscription. Cable TV is not available all over Germany.

IP television is the transmission of television (digital video and audio) through data networks such as DSL. IP television services are typically on a subscription basis paid for by the end user.

Television license

If you live in Germany and you own a radio, a television or a computer, then you are obliged to pay the TV license fee (Rundfunkgebühr), once per household, which is used to pay the German public broadcasting services.

If you want to find the best service for your telephone needs, you’ve come to the right place. It is extremely important to get telephone service that is right for you, when you need it, where you need it, and it’s especially important that it’s done right the first time.
