Apple Watch Plan

[tomh_]

I'm planning to upgrade my current SIM-only plan to a new O2 iPhone plan through Mobile Phones Direct, and I'll be using a PAC code to transfer my number.

I have two main questions:

1. I also have an Apple Watch Airtime Plan linked to my current O2 account. Can you confirm that this Apple Watch plan will seamlessly transfer and link to my new O2 iPhone contract? I want to make sure there are no issues with the Watch's cellular service after the upgrade.
2. What happens to my existing SIM-only plan once my number is transferred to the new iPhone plan via the PAC code? Will it be automatically cancelled, and are there any further steps I need to take regarding that old plan or SIM card?

You can't use a PAC to transfer O2 to O2.

You need a number migration although ideally you should just upgrade as it will be easier.

Either way, your watch should still work as it's linked to your phone number and the old contract will end when you either upgrade or migrate the number.
