Taking your phone number with you in the case of fixed-term contracts – this is how it works:

You want to change your mobile provider, but keep your cell phone number? Nothing easier than that! Simply follow the step-by-step instructions:

Cancel old cell phone contract

If you are still bound to your old cell phone contract, you must cancel it first. Make it easy for yourself and use our ready-made cancellation form. Download the PDF file, fill it out, print it out, sign it and send it to the provider. Keep in mind that the cancellation period is usually three months to the end of the term.

Tip: To be sure that the cancellation has actually been received, it is recommended to send it by registered mail. As a free alternative to written cancellation, many providers also offer cancellation via a corresponding online customer portal or by e-mail.

The number portability is already 90 to 120 days before the end of the contract possible. If you decide to transfer your phone number early, the existing contract will continue to run under a new number. Until the cancellation is effective.

Request number portability

When you order your new tariff online from us, simply tick "Yes, I would like to keep my phone number" at the end of your order.

Tip: To ensure that everything runs smoothly, the data in the old and new contracts must match. If your name or address has changed, inform your old mobile provider about it.

After you have ordered the number transfer, usually one to two weeks pass until the number is with the new provider. During this time, of course, you can still be reached.

Legal basis for number portability

With the conclusion of your very first mobile phone contract, you get a phone number that henceforth belongs to you. So you can take this number with you everywhere.

Technically, it works like this: As soon as the number transfer has been requested by you, the number is disconnected from the old connection and entered on the new connection. This process is officially also called number porting or number portability.

The possibility of number porting in mobile telephony has been stipulated in the German Telecommunications Act (TKG) since 2002. Accordingly, the old provider is obliged to release your cell phone number. It may not charge for it. The transfer of the cell phone number is possible in every network.

By law, you have the right to take your phone number with you at the earliest 120 days before and 30 days after the end of your contract. With some providers this is possible even 90 days after the end of the contract. However, in order to be processed in a timely manner, the porting request must be received by the new mobile provider no later than two to three weeks after the end of the contract.
