I have ordered a prepaid sim card with rufnummermitnahme

Hello,

I just realised too late that my contract with Winsim is ending today and I requested to take my number  and ordered an o2 prepaid sim card with the option of brining my number. 

But haven’t received any conformation that my number will be brought from there only that my order has been received and it will take up to 3 working days to receive my sim card. 

Here is the documnet I received from Winsim regarding the release of the number: edit o2_Manga: Link zu Google Drive entfernt

is everything fine like this, will I still have my number or is there anything else I should do? 

Thank you very much in advance
