Want to bring your number over to Three? No problem – you'll just need a PAC code from your old network. They know the drill, so get in touch with them and they'll sort it.
Your PAC will be a 9-character code, made up of 3 letters followed by 6 numbers. It'll be valid for 30 days, and you can choose any transfer date during that time (excluding weekends and bank holidays). If it's after 6pm, you won't be able to pick the next day.
Once this code has been used, your old account will be closed automatically.
For your security, we can only transfer your number over if you're the account holder or an authorised contact. The same goes for any change or cancellation requests once everything's under way. A third-party store can make a request to transfer your number for you, but we'll need to confirm you've given them the all-clear.
Remember: until we've transferred your number over from your old network, you'll need to use the number you get with your Three SIM.
