Can I combine balances on my new and old phones?

[JanT143]

My old phone has become a bit rickety, so can I put both balances on my latest phone...both on my o2 accounts?

@JanT143 The phone itself doesn't hold the balance. Your account information and balance is on your sim card. Do you have two accounts?

You need to pay off your old phone or contract first before you can upgrade.

You cannot add what you owe to an upgrade or new contract.
