Folks, I already asked this question some months ago, but now I finally left NL. (and there's no T-mobile here)
(and I can't find my old post to continue, so yeah here I am)
If I remember correctly, I can pay in advance for the remaining period (which is a month and half I believe), and pay extra to make my current SIM as a prepaid one.
Can you give me a hand dealing with this?
