hi!
I couldnt find this "o2 Rufnummer zu einem anderen Anbieter mitnehmen” option in Mein O2.
I dont have a fixed contract with O2, I have a Guthaben SimCard which I pay monthly….so is it still possible to take my O2 number to another provider?
thank you!
Hello
welcome to the o2 Community! Thank you for your enquiry with us.
Yes, of course you can take your prepaid number with you! 
Here is a description in English of how this works:
The most important information:
Number transfer to another provider
The number must be released first of all. This can be done on the hotline, in the chat and also via the Mein o2 app. The porting is free of charge.*
- Download the Mein o2 app and log in or register.
- Choose: Tarif & Optionen -> Rufnummernmitnahme –> Rufnummer jetzt freigeben. On the next page, you will see the data that must be entered for the new provider**. The approval is confirmed by SMS and is valid for 30 days.
Feel free to give us an update if everything worked out for you. If there are problems, we will do the release for you.
Kind regards
Jessica
