Good to know

We cannot extend contracts from1&1 and PŸUR – this can only be done directly with the provider. However, we will be happy to conclude new contracts with 1&1 and PŸUR with you, and we will check whether a change would be cheaper for you.

Extend or switch? We calculate both

  • We'll see what renewal offers your provider has for your contract and when they'll apply
  • We compare them with the tariffs of the other networks – and check which network is well received at your address
  • Without a new mobile phone: You keep your device and only renew the tariff
  • With a new mobile phone: We calculate what the device really costs over the runtime
  • If your current tariff is already a good fit, we'll tell you honestly
  • Set up a new mobile phone and transfer data – right in the store

There are often more in the store: Bonus promotions on renewal, combined benefits and offers that are not available online. And we also have a promotion for "Refer Friends" – just contact us.

This is how it works

  1. Bring documents with you

    Your ID and the last invoice or customer number. If you have it, also the customer password of your provider.

  2. Compare offers

    We show you the extension offers of your provider and also the alternatives - with all costs over the term.

  3. Decide

    You renew right in the store, change – or leave everything as it is. Your phone number remains yours in any case.
