Cancellation of Contract

https://info.o2online.de/kuendigung/

What is the process if I want to release my number from o2 and port it to another service provider?

The new provider will request your phone number at the end of your contract after you have canceled it.

Thank you so much for the information.

Hello ​@Pushpa Choudhary,

welcome to our o2 Community 🙂

I am sad to read that you are going to leave us.

Yes, with the form linked by Bumer you can cancel your contract and then for the date of cancellation move your number to your new provider.

Best Regards,

Gerrit
