Apple Watch 3 cannot activate plan

[KonstantinosIli]

Hello, for about a month I’ve been trying to have my plan added to my Apple Watch. I understand it is an old version but I am not sure why this is the case.

these are the errors I’ve been getting. Tried all sorts of things, Wi-Fi calling, increasing my cap, factory reset etc.

I would appreciate it if they would just tell me it is not supported.

If you already have an O2 Pay Monthly contract, and you already own an Apple Watch, you can set up mobile data via the Apple Watch app on your iPhone, @KonstantinosIli - https://www.o2.co.uk/apple-watch?osr=ts_applewatch

Here is the sequence that I have seen used in the Forum:

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 iData enabled on your account and pay bills by direct debit.

Good luck!

Thank you very much for your suggestions. During the past month I have tried everything but it has not worked. I carefully went through the forum to see I was not the only one and none of these steps helped.

Also, I cannot reset/remove the plan from the watch which is very annoying as I am getting all those notifications that setting up the data plan failed. This is an O2 issue for sure

On the mobile network (iphone>settings) there is an option I see LTE settings (Optional) what is this and is it okay it is empty?

Not certain that it is required with O2 but won't hurt to enter the apn settings anyway to check.
