Bringing iPhone and Apple Watch over to O2

[Spartan_Missile]

Hi - I'm two days from the end of my contract with EE and have spotted a good pay monthly SIM only contract on O2. I have a series 5 Apple Watch with cellular on my current contract that I'd want to bring over. When I search the O2 site the only info I can find is if I want to buy a watch. 

Can I add a cellular plan to an O2 sim only plan and any idea what the monthly cost would be?

Set up the data plan from the watch setup routine and it will walk you through buying an airtime plan.
https://www.o2.co.uk/help/phones-sims-and-devices/apple-watch
Open the Watch app on your iPhone and tap on ‘Mobile Data’.
Then tap ‘Set up mobile data’. You’ll be prompted to sign in with your My O2 username and password.
Once you’ve signed in, select your Apple Watch plan. Follow the steps on the screen to set up your Apple Watch Airtime Plan.
It can take up to 24 hours to activate, but sometimes it might take a little longer.
To check if your new Airtime Plan is active, open the Watch app on your iPhone and tap on ‘Mobile Data’. In the ‘Data Plan’ section, if you see O2 with the word ‘activating’ then you’ll have to wait a little longer for set up to complete. If you see O2 with an orange ‘i’ next to it, then you’re all set up.
If you get an error message at any ]oint, on the iPhone, go to Settings and select Privacy > Motion & Fitness and switch it on.
Then go back to the watch app/Mobile Data/set up mobile data plan and be ready to put your o2 username and password in to the resulting o2 screen. Also, it costs £5 monthly to add the airtime for the Apple Watch, so you'll need to authorise this after entering the o2 user name and password. The phone app will then say 'activating' which can take a day or so, but at that point, you can try doing a phone call direct from the watch to test it.
