Best Asia eSIM: one plan, every border

The classic Southeast Asia loop, Bangkok to Singapore to Bali, is three countries and three currencies in ten days, which is exactly the trip regional Asia eSIMs were built for. They cost more per GB than Thailand's famously cheap country plans, so the math only works when you actually cross borders.

Buy regional when
Buy regional for multi-country itineraries: the Thailand-Vietnam-Cambodia backpacker route, a Singapore-Malaysia-Indonesia hop, or Japan plus Korea in one trip. Also for cruise itineraries touching several Asian ports where country plans would multiply.
Buy a country plan when
Buy a country plan for single-country trips, and note that Asia has the world's cheapest country eSIMs: Thailand 10GB for under $10, Vietnam similar. A regional plan for a Bali-only holiday roughly doubles your cost for nothing.
Asia regional eSIM questions
Does an Asia regional eSIM cover China with working Google?
Plans that include China typically route its traffic through Hong Kong or Singapore carriers, so Google and WhatsApp usually work without a VPN, one of the quiet advantages over local SIMs. Confirm China is on the plan's country list; not all Asia regionals include it.
Which countries does the typical Asia plan cover?
The common core: Thailand, Vietnam, Malaysia, Singapore, Indonesia, Philippines, Cambodia, plus usually Japan, South Korea, Hong Kong and Taiwan. India appears on some lists and not others; check if the subcontinent is on your route.
Is a regional Asia eSIM worth it for Thailand plus one border run?
For a single Cambodia or Laos side trip from Thailand, yes; a Thailand-only plan leaves you offline at Angkor Wat. The regional premium of roughly $10-14 is cheaper than an emergency second eSIM bought on arrival.
