Watch5 4g calls not working

[Nagasaki]

My watch and pixel 7 were not playing nice together so I used switch up and got the S23 Ultra.

Annnnnd it's still not working. So that's £10 a month extra. Yay.

Anyway, 

I've read posts about hidden settings and making sure things like calls and texts from other devices is turned on so that's done but I did notice that even my pixel and this new phone show my number as the SIM cards original number before I transferred my number in from three.

Could this be the issue? And if it is how do I fix it so it shows the correct number?

Thanks

The number shown is irrelevant. If you had a new sim it would be blank and show no number at all.

Check this guide and make sure you've covered all the steps fully.

I followed the guide but section 7 is incorrect for me. I found it under connected devices. The setting is on and my watch is listed.

I did not go into o2 but my esim seems to be working, the watch says it's connected to 4g on o2.

Still sounds like an account issue so worth checking in your local store that it is setup correctly?
