How to put my new phone onto existing account

[Confused6]

I have got a new phone through a third party with o2. I already have an account with three other devices with o2 ( family members, but the accounts in my name as I pay the bills) I wanted to keep my old number and because it was not one of the devices that I already have with o2 I started a new account. How can I add this new device to my existing account as I cannot access my new device because when I log in, it just has my original account because I only have the one email.

You need a new email address to start a new MyO2.

O2 won't allow account merging currently.
