One larger data pool shared across the whole region. No running out in a different country.

QR code delivered in 5 minutes. Install before you fly, activate when you land.
Asia eSIM coverage
One Asia eSIM covers a huge, uneven region on a single plan.
Where it's strong
Tokyo and Seoul run dense, fast 5G. A regional plan earns its keep on a multi-country trip — Japan into South Korea, or a Thailand, Vietnam and Cambodia loop — since it skips buying a SIM at every border.
Know before you go
Which local carrier the plan routes through matters more here than almost anywhere — Telkomsel reaches remote Indonesian islands other networks don't, and China's Great Firewall means the plan needs to route internationally or Google, WhatsApp and Instagram stay blocked.
Common questions
Does an Asia eSIM work in China with the Great Firewall?
Only if it routes your traffic internationally. A plan that connects you to a local Chinese network will still have Google, WhatsApp, Instagram and Facebook blocked by the Great Firewall. Check whether the regional Asia plan's China coverage is firewall-bypassing before you rely on it there — if China is a major part of your trip, a dedicated China eSIM built for it is the safer choice.
Which countries does a regional Asia eSIM cover?
Typically the main travel destinations — Japan, South Korea, Thailand, Vietnam, Indonesia, Malaysia, Singapore, the Philippines, Taiwan, Hong Kong and more — but the exact list varies by plan. Always check the specific plan's country list, especially for South and Central Asia (India, Nepal, Sri Lanka, the Central Asian states) where coverage is less consistent.
Is coverage good outside the big cities in Asia?
In the tourist belts, yes; further out, it depends heavily on which local carrier the plan uses. City 5G in Japan, Korea, Singapore and the main Southeast Asian hubs is excellent. Remote islands, mountain regions and rural interiors can be patchy — download offline maps for places like Nusa Penida, rural Vietnam, or the Japanese Alps.
Should I get a regional Asia plan or a single-country eSIM?
A regional plan makes sense for a genuine multi-country trip. If you're spending your whole trip in one country — two weeks in Japan, or a Thailand beach holiday — a single-country eSIM is usually cheaper and routes on that country's networks more directly. Multi-stop favours regional; single-country favours dedicated.
