The time it takes to bring your own mobile device to Madstar Mobile varies. If you're just bringing your device, then the process can take as little as five minutes. If you're bringing over a phone number on your BYOMD device, then it will usually take 30 min to an hours depending how quickly your previous provider will release your number to Madstar Mobile. As long as you provide us with all the necessary information to port your number over it should be pretty quick and easy. In rare cases though, it could take as much as 24 hours. And porting over the weekend or after 5pm may take a little longer.
