Quick answer: The best eSIM for Asia depends on your route. For a trip through several countries, pick a regional Asia eSIM, which starts at $3.20 for 5 GB over 7 days in the eSIMzee catalog. If you spend most of your time in one country, a local plan for that country is usually the simpler choice.
What is the best eSIM for Asia?
There is no single winner, because Asia is a huge region. A traveler hopping between Thailand, Vietnam and Malaysia needs different coverage from someone staying two weeks in Japan.
The eSIMzee Asia page lists thousands of plans across the region. The six countries with the most plans there include Malaysia, Singapore, Thailand, China, Hong Kong and Macau.
Think of a regional eSIM like a rail pass and a country eSIM like a single ticket. The pass saves effort on a multi-stop trip. The ticket is cheaper and more focused if you stay put.
Which Asia eSIM plans are cheapest right now?
These picks come from the eSIMzee catalog. Each one is a plan that covers more than one Asian country. Check the provider's coverage list for your exact countries before you buy.

Prices from the eSIMzee catalog, checked on 2026-11-11. Providers change prices often.
For a two-week trip with 10 GB, LinkeSIM's 4-country Asia plan costs $4.95 for 15 days in the catalog. For a month of unlimited use, Airalo's Asialink plan costs $73.50 for 30 days.
Regional Asia eSIM or one eSIM per country?
Choose a regional eSIM if you cross borders and want to install only once. Choose country eSIMs if you stay mostly in one place and want the lowest price.
The catalog shows why. In Malaysia, the cheapest 10 GB plan for 15 days costs $3.91 from Abest eSIM, while LinkeSIM's 4-country Asia plan costs $4.95. In Japan, a 10 GB, 15-day plan costs $6.28 from eSIM+, while LinkeSIM's 8-country Asia plan costs $6.52.
So a regional plan is not always cheaper. Price your exact route on the comparison page before you decide.
Here are the lowest catalog prices for a short, small plan in popular countries:
- Thailand: Thirr, 1 GB for 3 days, $0.77.
- Japan: Yoho Mobile, 1 GB for 7 days, $0.74.
- Vietnam: Yoho Mobile, 1 GB for 1 day, $0.81.
How much data do you need in Asia?
Maps and messaging use little data, while video calls and streaming use a lot. Use the data calculator to estimate your trip.
If you do not want to watch a data meter, an unlimited plan is the easy choice. A fixed 5 GB or 10 GB plan is cheaper when you mostly use Wi-Fi at your hotel.
Will an Asia eSIM work on my phone?
You need an eSIM-compatible phone that is carrier-unlocked. Apple says iPhone XS, XS Max, XR and later support eSIM, and you need Wi-Fi or a hotspot to install a plan. Check your phone with the device checker.
China mainland is a special case. Apple notes that only certain iPhone models support eSIM there, and iPhones sold in mainland China, Hong Kong and Macao can have dual physical SIM trays instead. Check this before you plan a China stop.
Can I keep my home number while using an Asia eSIM?
Yes, if your phone supports two lines. Apple's dual SIM guidance says an iPhone uses one cellular data network at a time, so choose the travel eSIM as your data line and keep your home line for calls. None of the plans in the table above lists calls or SMS, so treat them as data-only.
Apple also says two different carriers need an unlocked iPhone. Unlock before you leave home.
Frequently asked questions
Does an Asia regional eSIM include Japan?
Not always. LinkeSIM's 8-country Asia plan shows up in Japan results, but the 4-country plans may not. Read the coverage list on the provider page first.
Is a regional eSIM cheaper than separate country eSIMs?
Sometimes. In the catalog, a 10 GB Malaysia plan costs $3.91 and a 4-country Asia plan costs $4.95, so the single-country plan wins if you only visit Malaysia.
Do I need to install a new eSIM at each border?
No, that is the point of a regional plan. You install once and the plan works in every covered country. Confirm that each of your countries is listed.
Can I use my travel eSIM in China?
Only on supported phones. Apple says only certain iPhone models support eSIM in China mainland. Check your model before you go.
Can I still get calls on my home number?
Yes, on a dual SIM phone. Keep your home line on for calls and texts, and choose the travel eSIM for data. Compare plans on the providers page.
