Best eSIM for Asia 2026: One Plan and Multiple Countries

Vacation or a business trip, it doesn’t matter; you need the best eSIM for Asia to stay online. Getting a physical SIM isn’t an option in 2026, and it’s also a hassle. With a reliable eSIM for Asia, you get coverage in all countries with one affordable plan. Unlimited data, no roaming fees, and reliable connection speeds.

Can you really ask for more? Well, that’s what you get from the best eSIM for Asia in 2026. After retesting dozens across Japan, China, Singapore, and Indonesia, our ranking shrank to only five options. It’s not a lot, but we promise that these five stood out as the most reliable choices during our Asian haul.

Best eSIM for Asia: Features, Plans & Prices Compared

Our shortlist provides an overview of the best options for your Asia travel. If you need more information before deciding, let’s review all five and go through their features, plans, and prices to help you make a more informed choice.

1. Ubigi

Ubigi offers the best eSIM for Asia with some of the lowest prices and support for up to 26 countries, more than anyone else on this list bar Airhub. Its flexibility means you can pay monthly or annually, but there’s also the one-off option. The lowest you can go is 500 MB for $2 per day. However, our favorite remains the Best Asia eSIM plan with 25 GB for 30 days for $44.

If you want unlimited data, the Best Asia plan offers it for $78 for a month, or $35 for a week. Ubigi supports 3G, 4G, and 5G connections, and in our latest tests in Japan, Indonesia, and Hong Kong, we had zero issues with coverage. Calling, gaming, and chatting were always on point on our phones and tablets.

We love Ubigi for its simple activation through QR code. Simultaneously, its app is one of the best, with data consumption tracking and notifications when you’re close to running out. We also appreciate unlimited data tethering, so if you’re traveling to Asia with a friend, you can both rely on a single eSIM for Asia.

Get Ubigi’s Asia eSIM

Ubigi lets you browse securely while traveling, providing either a home-country IP for unrestricted access to your usual content or a local IP for a more local experience, all with zero added latency. That matters more in Asia than anywhere else, given how many services behave differently depending on where your traffic appears to come from.

Granted, Ubigi lacks a phone number, and SMS and voice calls are out of the game. However, you get exemplary 24/7 customer support, with superb response times. If you decide on Ubigi, know that you can save 10% on your first purchase by using the promo code GIZMODO at checkout.

2. Saily

Saily is a bit pricier than Ubigi, but it’s still an impressive eSIM for Asia in 2026. Metered plans run from 1 GB, starting at $4.99 for seven days, up to 25 GB for 60 days at $48.99, which is the one most people pick. Unlimited options are available too. For five days, you’ll spend $21.99, and for a month, it’s $81.99.

Saily’s higher price is justified by its security features. It’s the only eSIM for Asia with an ad blocker and a virtual location that works much like a VPN. The Ultra plan even bundles NordVPN and NordPass. Saily’s app activation is a piece of cake, and its reliability is among the best in our tests.

There’s a bigger reason to look at Saily in 2026, and it has nothing to do with data. The app now sells airport lounge access and fast-track security passes directly at checkout, with no subscription needed. Anyone who has spent six hours in transit at Changi or Incheon knows what that’s worth. Frequent flyers can go further with Saily Ultra, a monthly plan bundling unlimited global connectivity, lounge access at over 1,000 airports, and the full Nord Security suite. The company was named “Rising Star” at the MVNOs World Congress in Amsterdam in June 2026.

Occasional speed drops may happen, but in major countries, like Japan and Hong Kong, Saily was very reliable. Its Asia eSIM plan supports 19 countries, and you also get Australia and New Zealand, which none of the others include. Saily also lets you buy the plan before your trip, with a 30-day activation period.

Overall, Saily is fantastic, but we’d love to see lower prices for unlimited data in Asia. Check our Saily promo code page for the current offers before you buy.

3. Holafly

Holafly is among the cheapest eSIMs for Asia with unlimited data. It starts at $3.90 per day, and the price falls the longer your plan runs. For instance, three days are $11.70, while the entire month is $74.90, roughly 10% less than Saily. Holafly lets you dodge roaming fees through solid Asia coverage.

You get 16 countries, including Japan, Hong Kong, Singapore, Taiwan, Indonesia, and Malaysia. We tested it primarily in the first three, and Holafly used a combination of 4G and 5G connections, mostly reliable during bandwidth-intensive activities. Holafly even lets you share your data with other devices.

However, that sharing is limited to 500 MB per day, which isn’t a lot, and the cap hasn’t moved in 2026. It also doesn’t offer voice calls and SMS, as it lacks a phone number. It compensates with its 24/7 support via live chat, one of the best we’ve tested, and an in-app activation that takes about two minutes.

Holafly could support more countries in Asia, but the 16 on the list are the major ones. Keep in mind that the Asia eSIM package excludes Oceania, which is bought separately. Saily is the only provider here that folds Australia and New Zealand into its Asia plan.

4. Airalo

Airalo was one of our favorite eSIMs for global travel, and it’s easy to see why. As one of the best eSIMs for Asia, it offers fast 5G speeds in most countries, often relying exclusively on it. Taiwan, Thailand, the Philippines, and Hong Kong are all on 5G, which makes a real difference day to day.

Airalo isn’t expensive, either. 1 GB of data for 7 days is $4.50. If you’re staying for a month, you can get 20 GB of data for $43.50. Airalo also includes lengthier plans for 90 and 180 days with 50 GB and 100 GB of data, priced at $89 and $164, which is good value at that volume.

Other than that, Airalo includes data tethering, 24/7 support, and a seamless setup through its app. It supports 18 Asian countries and works with operators such as Vodafone, CTM, KDDI, Taiwan Mobile, and AIS, for one of the strongest Asian footprints in 2026.

The gap is data. While Airalo offers phone number plans for other regions, it has none for Asia, and its regional Asia plan still has no unlimited option in 2026. If limitless data is what you’re after, Ubigi and Holafly are the two to look at.

5. Airhub

Airhub is our last eSIM for Asia, and it comes in two distinct flavours: Asia Pacific and Eurasia. The former is what you want, because it supports more countries. Its plans cover 15 to 30 countries and range from 3 GB to unlimited data. You can get unlimited data for a day for $6, with support for 15 countries.

You can ramp it up to 15 days and spend $56 for the same plan. The 30-country plan starts with 3 GB of data for a month at $9.50, while 12 GB costs $44.50. Airhub isn’t the cheapest, but it’s the only provider here that sells plans with data and a phone number, and you can pay monthly.

Airhub supports unlimited tethering, offers 24/7 support, and activates in-app. It’s even reachable on WhatsApp. Our only real gripe is reliability. Our 2026 tests confirmed that its speeds still aren’t up to par with the others, and 5G support remains limited, which hurts bandwidth-hungry activities.

Summary of the Best eSIMs for Asia

In summary, the five best eSIMs for Asia in 2026 are Ubigi, Saily, Holafly, Airalo, and Airhub. We had the best run with Ubigi, which excels at reliability, coverage, value for money, and ease of use, and it covers 26 countries against Saily’s 19 and Holafly’s 16.

Saily is a close second, and the one that has changed most this year. On top of its security tools, it now sells lounge access and fast-track passes inside the app, and it’s the only Asia plan here that includes Australia and New Zealand. Holafly remains one of the cheapest unlimited data picks.

Airalo and Airhub are slightly less impressive, but still have unique perks: 5G almost everywhere for the former, phone numbers and 30 countries for the latter. In the end, they’re some of the most popular eSIM providers in 2026, and are suitable even if Asia isn’t your next uncharted territory.

Frequently Asked Questions

What is the best eSIM for Asia?

Ubigi is the best eSIM for Asia overall. It covers 26 countries, starts at $2 for 500 MB over one day, and offers unlimited data from $35 for a week or $78 for a month, with 10% off using the GIZMODO code. Saily is the best alternative, with security tools, travel perks, and the only regional plan that also includes Australia and New Zealand.

Why do I need an eSIM for Asia?

Roaming across Asia is expensive and unreliable, and a physical local SIM only works in the country where you bought it. If you visit several countries, you would need to swap cards each time. One regional eSIM gives you coverage in at least 15 Asian countries on a single plan, activates before you arrive, and leaves your original SIM in the phone.

Which eSIM covers the most Asian countries?

Airhub covers up to 30 countries on its Asia Pacific plan, the widest of the five. Ubigi follows with 26, then Saily with 19 plus Australia and New Zealand, Airalo with 18, and Holafly with 16. If you are visiting only the major destinations, all five will cover them.

What is the cheapest eSIM for Asia?

Ubigi has the cheapest entry point at $2 for 500 MB over one day. For unlimited data, Holafly is cheapest on short trips at $3.90 per day, while Ubigi is cheapest for a full month at $78, undercutting Saily’s $81.99.

Can I get unlimited data on an Asia eSIM?

Yes, from Ubigi, Saily, Holafly and Airhub. Airalo is the exception: its regional Asia plan has no unlimited option, so you are limited to metered data up to 100 GB.

How do I know if my phone is compatible?

Check the compatibility page on the provider’s website. Saily has a Device Compatibility section where you search your model, and the others offer the same. Broadly, any recent iPhone or Samsung works, and even older models such as the Galaxy S20 or the iPhone XR are supported. Always check before you buy.
