Do you mean @BethanDavies that you previously had a contract that was under your mothers name, but you now have one in your name and you would like the number moved from the old to the new?
If yes, then you need to call o2 customer services and you need to request the number move and your mother needs to approve it.
This will end the contract with that number - so if it is not out of the minimum term you will need to pay the remaining balance.
Please note, this is not customer services and we cannot access your account. Do not publish personal details (email, phone number, bank account).
