Best eSIM for Asia (2026): Regional Plans Compared, Country Lists and Which to Buy
Updated · Wayfarro team
The best eSIM for Asia is the one whose country list matches your route, because the three regional plans we compared cover different countries at different prices. Wayfarro's Asia plan covers 13 countries with 10GB for 30 days at $26 and 7 days of unlimited at $29. Nomad's 14-country APAC plan charges $21 for the same 10GB, and Airalo's 18-country Asia plan charges $26 for 7 days of unlimited. Wayfarro's prices come straight from its store; Nomad's and Airalo's were checked in October 2026.
On price alone, Nomad is cheaper on fixed data and Airalo on unlimited. Wayfarro's case is a different country list, including Sri Lanka, Pakistan and Uzbekistan, plus a 1-day plan and long-stay bundles that run up to 180 days, which neither of the others sells for the region.
Best eSIM for Asia: regional plans compared
These are regional plans, taken from each provider's own regional page and confirmed in US dollars. Nomad sells two APAC plans; the table shows its 14-country one, which is the closer match. Providers change prices and run sales often, so check before you buy.

How to read this table: Nomad is cheaper than Wayfarro at every fixed size, and its 20GB and 50GB plans also run 45 days instead of 30. Airalo is cheaper at every unlimited length, and Nomad undercuts both at 5 and 10 days. Wayfarro is the only one with a 1-day plan, a 2GB plan, or fixed-data plans running 60, 90 and 180 days. A dash means the provider doesn't sell that exact plan, or we couldn't confirm its US-dollar price. Airalo's Asia page listed only unlimited plans when we checked.
Wayfarro's unlimited rows are its Unlimited Lite plans: 1GB a day at full speed, then 512 kbps until the next day. It also sells Unlimited Essential (1GB a day, then 1.25 Mbps) and Unlimited Plus (2GB a day, then 2 Mbps). Seven days costs $43 on Essential and $86 on Plus. Nomad states its APAC rule as 2GB a day at 4G/5G, then 512 kbps; Airalo's is 3GB a day at up to 20 Mbps, then 1 Mbps.
Check the country list before the price
"Asia" means a different set of countries on each provider's site, and the gaps are the countries people most want.
Wayfarro's 13 are South Korea, Thailand, Vietnam, Singapore, Malaysia, Indonesia, Taiwan, Hong Kong, Sri Lanka, Pakistan, Uzbekistan, Australia and New Zealand. Its 60-day, 90-day and 180-day plans add Macao. Nomad's 14 are Australia, China, Hong Kong, Indonesia, Japan, South Korea, Macao, Malaysia, New Zealand, the Philippines, Singapore, Thailand, Taiwan and Vietnam; a dearer 21-country version adds Bangladesh, Brunei, India, Cambodia, Laos, Sri Lanka, Nepal and Pakistan. Airalo says 18 countries but doesn't list them on the plan page, so open its coverage list before you pay.
What that means in practice:
- Japan and China: On Nomad's list, not on Wayfarro's. With Wayfarro you'd add a Japan plan to the order, and the same for China.
- The Philippines: On Nomad's list, not on Wayfarro's Asia plan. Wayfarro's smaller Southeast Asia plan does cover it, along with Thailand, Vietnam, Singapore and China.
- Indonesia and Bali: On both Wayfarro's and Nomad's lists, which is unusual; most Southeast Asia plans leave Indonesia out.
- Sri Lanka, Pakistan and Uzbekistan: Only on Wayfarro's 13 and Nomad's 21-country plan. If Colombo, Lahore or Samarkand is on the route, that decides it.
- Australia and New Zealand: On both Wayfarro's and Nomad's lists, so a Singapore–Sydney–Auckland trip is one plan.
- India, Cambodia, Laos and Nepal: Not on Wayfarro's list or Nomad's 14. Buy a country plan for each.
Which is the best eSIM for Asia for your route?
Match the plan to the route, then pick the provider that covers it:
- Korea, Taiwan and Hong Kong in two weeks: All three providers cover these. Nomad's 10GB at $21 is the cheapest fixed plan; Wayfarro's is $26. For unlimited, Airalo's 15 days at $49 beats Wayfarro's $76.
- Tokyo, Seoul and Bangkok: Nomad's 14-country plan is the only one here that covers Japan in the regional price. With Wayfarro, it's the Asia plan plus a Japan plan on one order.
- Bangkok, Singapore and Bali on a budget: Nomad's 5GB at $14 or Wayfarro's at $16. Wayfarro's 1GB at $4.50 is the plan to test the water with on a short trip.
- Colombo to Kuala Lumpur to Sydney: Wayfarro's 13 cover all three; Nomad's 14 don't include Sri Lanka. 10GB at $26 or 20GB at $44.
- Three months working across the region: Wayfarro's 50GB over 90 days at $155 and 100GB over 180 days at $316 are the only long-stay regional plans in the comparison, on one install with top-ups.
- A one-day layover in Singapore or Hong Kong: Wayfarro's 1-day unlimited at $7. Nobody else here sells a 1-day plan.
- Only one country: Skip the regional plan. Wayfarro's single-country plans cost less for the same data, and the South Korea and Japan guides on this site compare them with the competition.
Networks across the region
Wayfarro describes its Asia plan as running on tier-one partners in each country, without naming them on the plan page. Nomad names the partner in each of its APAC countries: KDDI au in Japan, China Unicom and China Mobile in China, Telkomsel in Indonesia, Maxis and DiGi in Malaysia, Globe in the Philippines, Optus in Australia and Spark in New Zealand, among others. Airalo's Asia page didn't name its networks when we checked.
Across the region the practical rule is the same on any network: cities are fast and the gaps are on islands, boats, overnight trains and mountain roads. A regional eSIM picks up the local partner as you cross each border; if it doesn't within a few minutes, toggle airplane mode.
How to set up an Asia eSIM
Install at home, switch it on when you land, and leave it on at every border. It takes a couple of minutes:
- Check your phone is unlocked and supports eSIM. iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy phones do.
- Install over Wi-Fi before you fly. Scan the QR code or use the one-tap install link. The step-by-step install guide covers iPhone and Android.
- Label it "Asia" so you can find it in settings.
- When you land, set the regional eSIM as your mobile-data line and turn on Data Roaming for it. Travel eSIMs are roaming profiles, so data won't connect without this.
- At each border, do nothing. The eSIM picks up the local partner network on its own.
- Keep your home SIM on for calls and texts with its own data roaming off, so bank verification codes still arrive.
Wayfarro's validity starts when the eSIM first connects in any covered country, not when you install it.
Why a regional plan beats airport SIMs across Asia
The regional plan earns its keep at the borders. Singapore, the Philippines and several other countries in the region require passport registration to buy a local SIM, and airport counters are slow for the same reason. A roaming eSIM skips the queue at each arrival and keeps the same number of apps logged in: Grab across Southeast Asia, KakaoTalk in Korea, LINE in Taiwan and Thailand, and the ride-hailing and payment apps that need a live connection to work.
The trade-off is price per gigabyte. If your trip is one country, a single-country plan is cheaper. If it's three or more, the regional plan saves you installing a new eSIM at every border, and the Trip Builder can fill the gaps, Japan included, on one order.
Bottom line
Nomad is the cheapest fixed-data Asia eSIM and the only regional plan here that includes Japan and China. Airalo is the cheapest for unlimited. Wayfarro is the best eSIM for Asia if your route includes Sri Lanka, Pakistan or Uzbekistan, if you want a 1-day plan, or if you're staying 60 days or more. Whichever you choose, read the country list before the price. See Wayfarro's Asia eSIM plans, or put the regional plan and a Japan plan on one order in the Trip Builder.
FAQ
Which countries does an Asia eSIM cover?
It depends on the provider, and the lists don't match. Wayfarro's Asia plan covers 13 countries: South Korea, Thailand, Vietnam, Singapore, Malaysia, Indonesia, Taiwan, Hong Kong, Sri Lanka, Pakistan, Uzbekistan, Australia and New Zealand, and its 60-day and longer plans add Macao. Nomad's 14-country APAC plan covers Japan, China, Macao and the Philippines instead of Sri Lanka, Pakistan and Uzbekistan. Airalo's Asia plan says 18 countries. Read the list before the price.
Does an Asia eSIM cover Japan?
Wayfarro's doesn't, and neither does its Asia plan cover China or the Philippines. Nomad's 14-country APAC plan includes all three. With Wayfarro you'd pair the Asia plan with a Japan plan on one order in the Trip Builder: 1GB for 7 days in Japan is $4 and 7 days of unlimited is $17.
Is Wayfarro cheaper than Nomad and Airalo for Asia?
No. Nomad's 14-country APAC plan is cheaper than Wayfarro's at every fixed size, by 50 cents on 1GB and by more as the plans grow, and Airalo is cheaper at every unlimited length. Wayfarro's case is coverage and plan shape: it's the only one of the three with a 1-day plan, fixed-data plans running 60 to 180 days, and Sri Lanka, Pakistan and Uzbekistan on the list. Competitor prices were checked in October 2026.
Is a regional Asia eSIM cheaper than buying a plan per country?
Usually not, if you're only visiting one or two countries. A single-country plan from Wayfarro costs less for the same data: 5GB for 30 days is $15 for South Korea alone against $16 on the regional plan. The regional plan wins when you're crossing three or more borders and don't want to install a new eSIM at each one.
What does unlimited mean on an Asia regional plan?
Every provider throttles after a daily allowance. Wayfarro's Unlimited Lite and Essential give 1GB a day at full speed, then 512 kbps or 1.25 Mbps; Unlimited Plus gives 2GB a day, then 2 Mbps. Nomad's APAC page states 2GB a day at 4G/5G, then 512 kbps. Airalo's Asia page states 3GB a day at up to 20 Mbps, then 1 Mbps. The allowance resets each day.
