You do have the ability to temporarily disable a number while keeping it reserved for future use by scrolling down the Configuration page.
However, you will still be charged for phone numbers that are temporarily disabled as there is no option to pause billing for Hypercare virtual pager numbers.
To avoid charges for numbers you’re not actively using, the recommended approach is to release or cancel these numbers, as simply disabling them does not stop the billing.
Contact Hypercare's support team at support@hypercare.com if you wish to release a number. In your email, please provide the name of your org, the number(s) you wish to cancel and reason for cancellation if possible so we can best support you.
