One eSIM for Asia, or one per country? the question this site exists for

Asia is not a destination, it is a dozen border crossings in a trench coat. A regional plan buys you convenience across all of them and charges you for it. A local pack is cheaper and stops working at the airport.

The premium is measurable. A 10GB regional plan is $22.99. The same 10GB inside Thailand is $9.79 from the same provider, GigSky. You are paying 2.3x for the privilege of not reinstalling at the next airport.

That trade is worth it at four countries and obvious on an open itinerary. It is a waste of money at one.

The regional picks for routes that cross borders

Every regional Asia plan same size, same table

¹ Yesim is the cheapest regional plan in this table and Trustpilot pulled its score while removing fake reviews (checked August 2026). The plans are real, so we link them; you deserve to know the rest. Nomad, Jetpac and Ubigi are not sold through our partners, so those rows are unlinked and we earn nothing when you buy them. Flags run in the order of the country rack above: Japan, China, India, Thailand, the Philippines, Taiwan, Hong Kong, Bali and Indonesia, Singapore, Malaysia, Nepal, Cambodia, the Maldives, Sri Lanka. A dimmed flag means the plan does not go there. Coverage counted country by country against each provider's own plan list, not off a marketing map; hover a flag for the country name.

Read the last column before the price column. "Asia Pacific" is a marketing region, not a map. The Maldives is in none of them. Nepal is in two. The Philippines is missing from the cheapest one. The full country-by-country coverage grid is here.

Where your traffic actually exits the fact nobody prints

A travel eSIM does not just rent you a local network. It carries your data back to its own gateway and releases it to the internet from there. That exit country is the IP address websites see. It decides whether your bank blocks you, whether streaming works, and in China, whether the firewall applies to you at all.

Exit countries recorded from provider network data on 2026-08-31. This is the single most useful fact about an Asia eSIM and almost no provider puts it on the product page.

"Unlimited" in Asia the caps, side by side

Every one of these is a daily cap, not a monthly one, so the plan resets each night rather than dying on day four. A published cap you can plan around beats a bigger cap you cannot see. Full breakdown with price per day: unlimited eSIMs for Asia.

How many GB for an Asia trip honest math

Assumes hotel and cafe wifi at night, which in most of Asia is genuinely good. Google Maps ≈ 5MB/hour navigating, Instagram ≈ 100MB per 15 min of Reels, a video call ≈ 700MB/hour. Camera translation is the Asia-specific surprise: roughly 20MB per menu you point at, and in Japan or China you will point at many.

Longer version with three real travel personas: how much data you need in Asia.

Install before you fly four steps

1. Buy and install at home, on wifi. Installation needs a working connection, and airport wifi in Asia usually wants an SMS code sent to a number you cannot receive.
2. Install the eSIM, then leave the line switched off until you land. Nearly every plan starts its clock on first connection, not at purchase.
3. On landing: turn the eSIM line on, enable data roaming for that line only, and leave your home SIM on for SMS codes with its data off.
4. Nothing after five minutes? Select the network by hand. Every country page here lists which networks your provider is allowed to use.
