BNESIM

A small business sending staff abroad regularly runs into a specific annoyance that pure data eSIMs don't solve: colleagues and clients calling a number that changes every trip, or not being able to call the traveling employee's phone at all since most travel eSIMs carry no phone number whatsoever. BNESIM, incorporated in Hong Kong since 2017, addresses that with an optional Virtual SIM add-on layered on top of its base data plan, giving the traveler a real number with per-minute calling and texting that can stay consistent across trips.

The base data eSIM itself is priced per gigabyte with validity stretching up to 180 days, useful for buying ahead of an upcoming trip, and an unlimited tier exists for select destinations, though BNESIM doesn't publish exactly where its fair-use throttle kicks in. Coverage claims vary by source between roughly 120 and 200-plus countries, so it's worth confirming your specific destination is well served before relying on it for a business trip. Auto-renewal is on by default, worth switching off if you don't want to be re-billed automatically. It's a sensible pick for a small team or solo consultant who wants a stable, callable number more than the absolute cheapest data rate.
