Simply cancel or park your phone number and reactivate it later.
Open My Rinkel
Click on “Account” on the top right.
Click on “Subscription” and scroll down to “Phone numbers”.
Click on the cross behind the phone number you want to cancel or suspend.
Select “Yes, park this number” or “Cancel”.
When you cancel, the phone number remains active until the end of the monthly period. Don't want your phone number to be released? Then choose "Park this number". This way, your telephone number will be reserved for at least one year.
