Unable to buy data plan for Apple watch

Hi - i'm hoping someone out there can help. I've spent probably 3 hours on the phone with O2 Customer Care, and hour with Apple Customer care and still no solution.

I'm trying to set up mobile service on a cellular Apple watch.

I have a new airtime plan (eSim) for an iPhone 11. I have paired it to a series 7 Apple watch. Both on latest OS.

When i try to 'Set up mobile service' from the Watch app on the iPhone, a window opens (black with white text) titled 'O2' and with the message 'Please wait while the page is loading. This should only take a few seconds to complete.' but this is as far as I get, as the page then closes and returns me to the 'Set up mobile service' page.

My understanding is that should i have been successful, i would have been taken to an O2 Login screen where i could then go ahead and buy a data plan for the watch. I never get to that screen.

I made sure the iPhone was on 4G when i did this.

I've paired and un-paired the watch multiple times.

I've reset (erased) the watch multiple times.

I've restarted the watch and phone multiple times.

O2 Customer Care have told me everything looks fine their side, and it should work. They've suggested i go into a store. The store (when i phoned them) suggested that i need to talk to O2 Customer Care!!

O2 Customer Care tell me it must be a problem with the device, and I should contact Apple.

Someone help please!!

@SmallTownHero

The only information we have is this guide

And dont call the store, pop in and speak to them, as over the phone they will tell you to speak to CS

It might be worth speaking to Apple as well, just to get them to check there is nothing tied to the watch on the Apple Servers, but I doubt owt will.
