How can I delete a phone number?

You can unsubscribe a number whenever you want. There will not be any additional renewal charges thereafter.

To unsubscribe a number, sign into the web app,  click on the settings icon bottom left and then go to Company Settings -> Telephony -> Phone numbers.

Click on the number you want to unsubscribe, and then select Number details in the right window.

Click on Change and then scroll down and select the option Do not renew and then select Done.

The number will now be removed automatically from your account at the next renewal date.
