Number porting is done through one of or many exchange partners and is unpredictable. The first part of it requires thorough documentation. For Skype users, we need proof that the number is in your Skype Manager AND the invoice connected to it from Skype Manager (found in Reports). Once that is submitted, we forward to our exchange and wait for them to determine if the number can be ported or not. Once it is approved, we give the go ahead after which the process can take anywhere for 3-4 weeks.
