Changing phone number from different accounts

[ThomasFLawrie]

My current number I use is from a monthly contract under my Dad's name, and I've set up a new monthly contract under my own name - how would I go about carrying the number I had before onto this new one? The guides I can find don't help because technically the phone number is going between two different people, not between two accounts I personally hold. Would I use a PAC or STAC code? How would I do this?

Just call to migrate your number.

Your dad will need to be present to give permission.

Do I need to have put the new sim in my phone and 'activated' it, so to speak, before I do so? Or does it not matter?

Your new sim should be activated already with a different number so you can use that until you migrate your number.
