BNESIM

BNESIM operates as a Hong Kong-based eSIM reseller that's been active since 2017, serving the Asia-Pacific region and beyond. The 200-plus-country catalog includes mainland China with fixed-gigabyte packages that stay valid for up to 180 days, giving longer validity windows than many competitors.

The optional Virtual SIM add-on provides a real phone number if you need inbound calls or SMS verification, expanding its appeal beyond data-only travelers.
