Number porting varies, but a normal port time is around 2-3 weeks. Once the port has been approved, a cut-over date and time will be set and we will advise you of those details.
You might prefer to specify a particular date for the port to take place. This must be at most 30 days from the date of your port application, however this date will always be considered a "best effort only". VoIP Server cannot to guarantee that the port will be completed on your preferred date.
