Moving to Vodafone
If you're moving from another network to Vodafone you'll probably want to keep your phone number. When you get your new phone on Vodafone you'll be given a temporary number so you can start using your phone right away, then you'll need to contact your old network and ask them for a PAC code. Once you have this code just head over to this form on Vodafone's site and enter your details. That done your number will be moved to your new phone in 1 working day.
