Move mobile subscription to a different client number

My wife and I both have KPN Sim cards and a monthly subscription.

We also have TV and Internet through KPN

Both of the simcardsare linked to my Klantnummer. The TV and Internet are linked to my wife’s Klantnummer.

I would like to move my wife’s sim card and mobile subscription to her Klantnummer and billing details.

I would like to move my own sim card and mobile subscription to a business subscription.

I can’ find how to do this via the app or online.
