@Hurdent You are billed for both at the same time as it’s one account that’s billed. You don’t have the option to split the bill and pay via two accounts. You have 2 options, one would be to put the payment on your EE account for your watch before you are billed so that will be taken along side the bill for the rest of the payment for the phone. You have to do this manually each month before you get billed or payment will be taken via the payment method you already have
You could transfer the payment from one bank account to your other bank account to cover this payment yourself, you can even set up a standing order to do this.
