4G LTE Module

I'm thinking about purchasing the 4G LTE module for the WIN Max 2 2023. Does anybody know which phone companies actually operate on the advertised bands? I'd also love to hear about your experiences with the module. I'm specifically looking for companies in the USA and Japan that have good nationwide coverage on the listed bands.

Also, the Ali Express page for the module has a separate option for users in Japan. Does that mean that the module that everyone else in the world potentially uses would be inoperable with Japanese SIM cards?

Thank you for your time.
