Unable to remove a non-existent cellular plan on my Apple Watch Ultra 2

Thanks for the response. No, it was new from the official apple retailer. My mobile that it paired with is already using the same cellular provider. My old watch it replaced was already using the cellular with no problem. I spoken to the cellular provider and as I said, they have no connection and of course don’t charge me for it yet the watch is just continues to say ‘Virgin’ waiting and I can’t delete or remove it and Virgin can’t cancel anything as nothing is with them to cancel….
