"This Apple Watch does not support Spark NZ Mobile in this region."

Hi guys,

When I try to configure the new apple watch series 4 GPS + LTE with the mobile data (eSIM), I get the following error in the Watch app:

This Apple Watch does not support Spark NZ Mobile in this region. Apple Watch can only be used with data plans that are certified by your carrier, and for your region. Visit https:// www.apple.com/au/watch/cellular for more information about Apple Watch data plans.

Also the Set up Mobile Data is greyed out.

Do you have any idea?

I've checked with my carrier and everything is great from their side.

I also live in New Zealand but bought the watch for U.S.A
