As soon as you want to transfer your existing number to a new mobile provider, the porting date is always set by the current mobile provider. Unfortunately, we cannot directly influence the porting date. This is solely dependent on your current mobile provider, as they are currently still in "possession" of the number. Only they know your current contract conditions and thus the permissible porting date/cancellation date.


The porting request process is as follows:
  1. We will send a porting request to your current mobile provider with your chosen termination type (early termination of contract) or (end of contract term).
  2. Your current mobile provider receives the porting/cancellation request and enters a porting/cancellation date according to the current contract conditions.
  3. He sends the porting request back to us with the porting date, and we inform you of this date by e-mail.
  4. On this porting date, the SIM card can be inserted into the cell phone and used with the previous number. In the case of an eSIM, you will receive a download link by e-mail on this date.

Early termination of contract:
In principle, you can also leave your current mobile operator before the subscription contract expires (early contract termination), but they might charge you a penalty fee for not complying with the terms of the contract. With this contract termination, there is also an option to set a date for the porting request. Usually, the date of the porting request is accepted, as long as it is a business day. We therefore recommend that you first discuss the matter with your current mobile service provider so that you are not charged any unforeseen costs for early contract termination. If you are considering (early) contract termination, please feel free to contact our support.
