Lets assume two situations:
1. From abonament subscription to Tmobile and I already cancelled my contract at another provider
2. From prepaid to Tmobile
I am interested only in the duration of procedures around number transfer (and not notice period to cancel my abonament at other provider which is often 1 month)

From prepaid to T-Mobile makes absolutely no difference. Also, when switching from T-Mobile prepaid to a T-Mobile subscription, there is no time needed to transfer the number.
