Ready to make the move but not sure how? Here’s everything you need to know about switching your mobile provider.
Make sure your phone’s unlocked
If you’re joining us, make sure your phone’s unlocked. You can find out how to unlock your phone in our device support.
Text to get your PAC?
Your Port Authorisation Code or PAC is a 9-character code that’s made up of 3 letters and 6 numbers. It lets you move your number to a different network. To get it, either call your old network provider or text ‘PAC’ and your date of birth – DDMMYY – to 65075. Simple.
Transfer your number?
To transfer your old number over to us, fill in our online form.
If you’ve already taken out a Pay Monthly plan with us, then you’ll need to enter your details. Name, date of birth, and full address too.
What happens next?
We’ll send you a text or email to confirm your number has been moved over. If you send your form before 5pm during the week, your number should be transferred the next working day.
There you go. Switching networks doesn’t have to be a headache. For more details about why you should join us, see Reasons to Choose Three. Check out our Switching to Three Support section for any further info, too.
