Opt in immediate number portability

Do it by yourself, logged in in meino2 .

I coudn’t find it in meino2 =( can you send me the link? or image?

I don’t have such menu, maybe because I have o2 loop plan?
 

This is what I have in sim card settings menu
 

Quite.

You’ve got to contact the customer care (e.g. the hotline support). Alternatively you can wait here for an o2_moderator to release your number, but due to the pandemic you must have patience.

Thanks a lot, Kurt! 

You´re welcome!
