Hello ​@AChahianchi, welcome to our Community! Very understandable that you want to cancel your subscription if you don't use it for the next four months. I wanted to check with you, but I see that you're missing your full name, zip code + house number, date of birth and the last four numbers of your bank account in your profile. Can you fill it in? If you're still in contract and you want to cancel it, you do need to buy out the subscription. You will then pay 50% of the monthly costs for the remaining months and the device credit you currently have outstanding (if you have it). Keep in mind to give one month's notice. If I process the cancellation for you today, the earliest it can be stopped is 13/01/25. Since you want to keep your number, I can arrange for your subscription to be converted to a PrePaid connection on that day, so your number will still remain active. You will then need to keep the number active once every 6 months. By active usage we mean: 

• Calling yourself (if the call is answered)
• Recording someone else's voicemail
• Sending text messages
• Top up credit yourself
• Mobile internet
• Forwarded call (only if the party forwarded to accepts the call).

If you perform 1 of the above items once every 6 months, your number will remain active. If not, it will expire, but you will receive reminders. We do not want to keep the number active on our network unnecessarily. 

If you can fill in the details in your profile, I can calculate how much it will cost if you want to cancel your contract (if you're still in contract). Afther that, I just need to do an additional verification. Then I can take care of the cancellation and conversion to PrePaid for you!
