Hi @Magdelaine, welcome to our Forum and thank you for your message.

You can convert your KPN subscription to prepaid from the date your contract ends. You can best arrange this through our customer service. I can not convert this for you because it is actually a cancellation and we have a specific department for that. Once you have contact with that department, you indicate that you want to cancel but want to keep the number for prepaid. Then that is arranged 

Ways to get in touch with that department:
- Let us call you back at: KPN.com/cancel
- Call yourself: 0800-0402 / 1200 (toll free)
- Chat: https://www.kpn.com/service-c.htm > mobiel > scroll to the botum untill you see this:

If you have any questions, feel free to ask!

Hi @Magdelaine, I have had no response. Did you receive enough information about switching to prepaid?
