Apple Watch No Sim

[Haylzzz74]

I have been having “no connection” problems on my apple watch but ive noticed today if i keep my iphone open it doesnt lose signal on my watch when i leave my iphone at home to go for a walk with just my watch. But in the settings section on my aplle watch under the “about” section under ICCID it says NO SIM, does this mean my apple watch plan hasnt been provisioned fully? Any help would be appreciated. TIA

Check the setup routine has been done correctly.

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.

Hi @M15 many thanks for your reply, this is how i originally set up the air time plan, do you think i need to remove it and try reinstalling it again? I have tried this before bit it still behaved the same. I dont u derstand why i have to leave my iphone open when i go out with just my watch for the cellular to remain stable?

With Apple devices, you shouldn't even need the phone to be switched on, so something isn't setting up properly. 

Try it again and make sure you have wifi and 4g calling enabled on your phone first.
