Apple Watch data plan - error 90

[Pwilliams73625]

I’m trying to add a data plan to my new Apple Watch but keep getting error 90.  customer service seem clueless and this board is littered with similar message most nearly 10 months ago.  But no solutions posted.

Can someone point me in the right direction?

Thanks,

Paul.
