Keep your existing number

When you sign up to an iPhone tariff, you can transfer your existing number to your new iPhone account. You'll be asked whether you want to keep your existing number during the online activation process. If you are moving from another network provider and want to keep your number, you'll need to contact them for a PAC code.

Once you've completed the activation process, we'll contact you to let you know when your existing number will be transferred to your iPhone. This can take up to 2 working days, but don't worry, we'll provide you with a temporary number so you can start using your iPhone straight away.

You'll need to ensure that you have already transferred your contacts to your address book and listened to any voicemails before activating your iPhone account as they will be deleted from your old SIM when your new number is transferred.
