The Telekom network is considered the best mobile network in Germany – the mobile phone contracts of the Magenta group are correspondingly expensive.

Anyone who opens the Telekom tariff page without knowing it may fall off their chair with surprise: The cheapest tariff costs just under 35 euros a month – with a term of two years and including connection fee, you transfer over 800 euros to the mobile operator.

Luckily, there are much cheaper ways to (proven to be) the best network: a whole range of providers now have mobile phone contracts that also transmit in the Telekom network.

In the video: New mobile phone contract: You should definitely avoid these mistakes

You have to pay attention to this with cheap mobile phone contracts

  • No top speed: Compared to the official Telekom tariffs, the discounter tariffs in the Telekom network almost always differ in terms of speed: both download and upload speeds are usually limited. The download speed is often a maximum of 21.6, 25 or 50 megabits per second – theoretically up to 300 Mbit/s would be possible in the Telekom network.
  • No 5G: 5G is already included in the current Telekom tariffs – this is not the case with third-party providers. This is not a problem at the moment, because 5G is only available in a few places anyway and 5G smartphones are only appearing gradually.
  • Higher price from the 25th month: Please note: Some cheap tariffs become significantly more expensive after the 25th month. Therefore: keep an eye on the notice period and cancel in good time before the automatic contract extension.
