Apple Watch airtime error 14 message

[Chrisx20]

So I bought an Apple Watch Series 7 not from o2. Added it to my airtime and so far it is not working, trying to go into mobile data options on the app and I only get error 14 showing, no options to do anything else. Called o2, no help at all. Messaged o2 about this issue and they sent out an esim - no instructions whatsoever that work with a watch. Honestly it’s been weeks and o2 have been no help so far and getting help is terribly difficult. Has anyone got any help? Watch says no sim/no network. Yes it is a cellular model.

For starters, the esim is embedded in the watch, so getting "another" won't be any help at all.

Check you have followed to setup routine fully as outlined below:

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 point, 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.
You also need to have 4g and wifi calling and iData enabled on your account and pay bills by direct debit.

I have gone through all of that weeks ago, literally everything was set up but the watch just doesn’t recognise anything has been “switched on” on o2’s side. Yes I knew about the esim being built in, sending me one was all o2’s tech supports idea.
