eSIM for Asia — 23 Countries, One eSIM
Asia is the widest region in the catalog: the same eSIM bills $1.43/GB in Malaysia, Thailand and Vietnam and $110.59/GB in Bhutan — a factor of 77. That range is not spread across the map, though; it sits at one edge of it. Remove the two destinations flagged premium and the remaining 21 countries fit inside a ×12.9 band, with 9 of them priced identically to each other.

Rates are live retail per-MB prices — the same table that bills customers (see the full price index and all 193 countries).
The ×77 spread is two countries wide
The headline number comes from exactly two entries. the Maldives and Bhutan are the only members of this region carrying the premium flag, and they are also its two most expensive rows. The largest single price step anywhere in the region is the jump from Nepal to the Maldives — ×4.0 between neighbours in the sorted table above.
Below that step the region tops out at $18.43/GB in Nepal, and the 21 countries underneath span ×12.9 in total. The practical read: if your route does not include the Maldives and Bhutan, the spread is not something you need to plan around.
Nine countries, one rate
The region median, $2.97/GB, is not an average landing between scattered values — it is the most common rate in the region. 9 of 23 countries sit on exactly that figure: Bangladesh, Cambodia, Hong Kong, India, Laos, Macau, the Republic of Korea, Singapore and Sri Lanka. 16 members are at or below it.
The floor, $1.43/GB ($0.0014 per megabyte), is shared by Malaysia, Thailand and Vietnam — the same rate in all three, so a route through them has no cheap leg and no expensive leg. Taken together, 19 of 23 countries fall in a single band from $1.43 to $4.61/GB — everything priced at or under twice the median.
What the $20 minimum buys, country by country
The minimum top-up is $20, billed per megabyte from one balance, so the same top-up converts differently in every country. At the region floor it is roughly 13.9 GB in Malaysia, Thailand and Vietnam. At the region median rate, roughly 6.7 GB. In Bhutan, the region's most expensive entry at $0.1080 per megabyte, the same $20 is roughly 185 MB.
Nothing expires between those numbers: what is left after one country is spent at the next country's rate, on the same eSIM, with no repurchase at the border. That is why the spread rarely needs managing — one top-up is sized for the whole trip, not per destination.
How this page relates to the country guides
3 countries in this region have a dedicated destination guide: Thailand, Indonesia and Japan. All 3 sit at or below the region median, topping out at $2.15/GB — the guides cover the region's cheap end, not its outliers.
Each one is written for a single destination and goes into setup and arrival detail; this page does the other job, which is the rate map across all 23 countries in the region and the 193 in the full catalog. Read the table first to see where each stop on your route lands, then the guide for the country you are actually landing in.

FAQ
Does one Roamzy eSIM really cover all 23 countries in Asia?
Yes — one eSIM profile, one balance. Crossing a border switches you to that country's per-MB rate automatically; there is nothing to re-buy or re-install.
How is data billed across Asia?
Per megabyte, from a prepaid USDT/USDC balance. Each country has its own rate (from $1.43/GB in Malaysia in this region); you pay the local rate only for the megabytes you use there, and the balance never expires between trips.
Which country in Asia costs the most, and how much data does the minimum top-up buy there?
Bhutan, at $110.59/GB ($0.1080 per megabyte). The $20 minimum top-up is roughly 185 MB there, against roughly 13.9 GB at the region's floor rate of $1.43/GB. Same eSIM, same balance — only the per-megabyte rate changes.
Do I need a new eSIM for a multi-country trip?
No. That is the point: install once, top up once, and the same eSIM works across all 193 covered countries — this region and beyond. See the install guides to set up before you fly.
