Billing for phone numbers will commence as soon as we are able to schedule your port date. Typically, port dates are scheduled roughly 7 days prior to the completion of the port itself. Accordingly, Twilio will commence billing you a monthly fee for your ported phone numbers roughly 7 days prior to the port date. Thereafter, these phone numbers will be billed monthly on this same day of the month (i.e., the date the port date was scheduled, not the port date itself) or the last day of the month if that day of the month does not occur in a particular month (e.g., February 28 if Twilio was originally able to schedule your port on January 31).
When the port date is scheduled, you will receive an email notifying you of your porting date and be able to see a “port scheduled” status next to your phone number in your Porting Requests page. For the period from when you submit your port requested until we are able to schedule a port date, you will not be billed for the phone numbers. We also do not charge anything for our porting services.
