Hello @Seven_of_nine,

thank you for your contribution to our o2 community!

Did you swap your number or port your number?
Unfortunately, it is only possible to change the number at very short notice. But we could try! I can't promise that it will work. But I would be happy to ask the relevant department.
As I said, write us briefly whether you have had a number exchange (changed your number internally) or whether you have had your number ported (number ported from one contract to another).
Is it generally the phone number with which you are also registered here in the forum? Just write whether yes or no, please do not write the phone number here publicly as an answer. If it is a different one, I will switch to private messages.

Kind regards
Jessi

Hi Jessi,

I have contract with o2, it’s with the same condition just with another number, I didn’t change anything else except number internally.

Tnx for quick response :)

But it’s ok, I solved the problem. 
tnx anyway for your help

Es würde mich überraschen, wenn der Rückwechsel nach einem Monat doch noch möglich ist...

Hello @Seven_of_nine,
