Best eSIM for Asia 2026: One Plan, 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 testing 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 best, most reliable options 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 and go through their features, plans, and prices to help you make a more informed choice.

1. Ubigi (Starts at $2 for 500 MB per day)

Ubigi offers the best eSIM for Asia with some of the lowest prices and support for up to 26 countries. 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 is 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 for $35 for a week. Ubigi supports 3G, 4G, and 5G connections, and in our 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.

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, so you can enjoy apps, news, entertainment, and sports seamlessly, all with zero added latency.

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 on checkout.

2. Saily (Starts at $4.99 for 1 GB for 7 days)

Saily is a bit pricier than Ubigi, but it’s still an impressive eSIM for Asia in 2026. It offers from 1 GB to unlimited data, where the latter starts at $4.99 for seven days. People mostly go for 25 GB for 60 days for $48.99. Luckily, unlimited options are available, as well. For five days, you’ll spend $21.99, and for a month, it’s $81.99.

Saily’s higher price is justified by its use of security features. It’s the only eSIM for Asia travel with an ad blocker and a virtual location, which mimics the VPN. The Ultra plan even has NordVPN and NordLocker for more convenience. Saily’s app activation is a piece of cake, and its reliability is among the best in our tests.

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. Moreover, Saily lets you buy the plan before your trip, and provides a 30-day activation period, which is plenty.

Overall, Saily is fantastic, but we’d love to see lower prices for unlimited data for Asia and a phone number option that would enable SMS and voice calls. But even without those, you get 4G/5G coverage for seamless VoIP use.

3. Holafly (Starts at $3.90 for unlimited data daily)

Holafly is among the cheapest eSIMs for Asia with unlimited data. It starts at $3.90 per day, but the price goes down the longer your plan is. For instance, three days are $11.70, but the entire month is only $74.90, about 10% less than Saily. Holafly lets you dodge roaming fees through top-notch Asia coverage.

You get 16 countries, including Japan, Hong Kong, Singapore, Taiwan, Indonesia, Malaysia, and more. 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, it’s limited to 500 MB per day, which isn’t a lot. It also doesn’t offer voice calls and SMS, as it lacks a phone number. Luckily, it compensates for both with its 24/7 support via live chat, one of the best we’ve tested. Another point is ease of use, with activation in the app that takes virtually two minutes.

Holafly could support more countries in Asia, but the 16 that are there are the major ones, and you likely won’t need more. Keep in mind that the Asia eSIM package excludes Oceania, and these are bought separately.

4. Airalo (Starts at $4.50 for 1 GB of data for 7 days)

Airalo was one of our favorite eSIMs for global travel; it’s easy to see why. As the best eSIM for Asia (or one of), it offers fast 5G speeds in most Asian countries, often relying exclusively on it. For instance, Taiwan, Thailand, the Philippines, and Hong Kong are all on 5G, making the internet experience wonderful.

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. Moreover, Airalo includes lengthier plans for 90 and 180 days with 50 GB and 100 GB of data, respectively. Their prices are $89 and $164, far from expensive for this amount of data.

Other than that, Airalo includes data tethering, 24/7 support, and a seamless setup through its easy-to-use app. It also supports 18 Asian countries and works with some of the most renowned telecom operators, such as Vodafone, CTM, KDDI, Taiwan Mobile, and AIS, for one of the best Asian coverages in 2026.

While it offers phone number plans for other regions, it lacks them for Asia, plus, there are no unlimited data plans, which would’ve been nice, as other options have them.

5. Airhub (Starts at $6 for unlimited data daily)

Airhub is our last eSIM for Asia with two distinct options: Asia Pacific and Eurasia. The former is what you want because it supports more countries. Its plans support 15 to 30 countries and range from 3 GB to unlimited data. Airhub is very flexible. 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 plan with 30 countries starts with 3 GB of data for a month for $9.50. Meanwhile, 12 GB of data costs $44.50. It’s easy to see Airhub isn’t the cheapest, but the good news is, it offers plans with data and a phone number, plus, you can pay monthly.

Airhub supports unlimited tethering, offers 24/7 support, and has an in-app activation. It’s even available on WhatsApp to get in touch more easily. Our only gripe is its reliability. Our tests revealed that its speeds aren’t up to par with the others. Plus, 5G support is limited, which may hinder bandwidth-hungry activities.

Why Do I Need an eSIM for Asia?

The reason is simple: you need the best eSIM for Asia to stay connected and avoid obnoxious roaming charges. Roaming packages are very expensive and usually not worth the faff. Similarly, a physical SIM from Asia limits you to one country you’re currently in. If you visit multiple countries, it becomes annoying.

You need to keep all your SIMs and swap them out as you go. With an eSIM, you effectively purchase one plan and have coverage in at least 15 Asian countries. Our best eSIMs for Asia cooperate with some of the most prevalent telecoms in Asia, offering reliable connections and 5G speeds for all activities.

On top of that, they’re inexpensive for all the data you’re getting. Our favorite aspect is that you can activate your eSIM for Asia before you arrive. Conversely, you can’t get a physical SIM unless you get there, and even then, it’s a hassle. That said, eSIMs blend convenience and superb connectivity for a low price.

How to Know if My Phone is Compatible?

You can do it the old-fashioned way by checking within your phone’s settings. However, we love using official eSIM websites for that. Ubigi, Saily, and others have sections where you can see if your phone is compatible with them. If we take Saily as an example, you have the Device Compatibility section.

Click it and search for your device. We searched for our Galaxy S25, and as you see above, it appeared, which means it’s supported. Generally speaking, newer Samsung phones and iPhones will work, but even older ones, like the Galaxy S20 or the XR, will also work. Always check for compatibility before buying an eSIM.

You don’t want to get it and realize it’s useless when it’s too late.

Summary of the Best eSIMs for Asia
