Airalo vs Holafly vs Monsoon: Asia eSIM Comparison 2026

Airalo vs Holafly vs Monsoon Travellers for an Asia trip in 2026 comes down to three trade-offs: how many countries one profile covers, whether the plan is metered or unlimited, and how the price lands per gigabyte, with the Monsoon Travellers Southeast Asia regional plan starting at $2.90 for 1 GB / 7 days (as of September 2026). This guide covers what each provider actually sells, where the tiers overlap, and how to pick between them depending on your route and your data habits.

Last updated: September 2026

What Each Provider Actually Sells for Asia

All three sell travel eSIMs, but the catalogue shape and the pricing model differ enough that the right pick depends on your trip. Airalo and Holafly are global-catalogue providers with hundreds of destinations. Monsoon Travellers is Asia-focused with a tighter, region-specific catalogue.

Airalo: metered global catalogue

Airalo sells single-country and regional metered plans across most of the world, with an Asia regional plan alongside the per-country ones. You buy a data pot (typically 1 GB to 20 GB) on a 7, 15 or 30-day window and top up when it runs out. We do not quote their price ladder here because they revise it regularly; check airalo.com for current prices.

Holafly: unlimited-data global catalogue

Holafly's headline product is unlimited data sold on daily windows rather than a data pot. Plans run for a fixed number of days at an all-you-can-use rate, usually with a fair-use policy that reduces speeds above a daily threshold. Check esim.holafly.com for current daily rates.

Monsoon Travellers: Asia-focused catalogue

Monsoon Travellers publishes 12 single-country plans and two regional Asia plans, and does not sell outside the region. On top of the country plans we run a Southeast Asia regional plan covering seven countries on one profile, and a wider Asia regional plan for itineraries that also include South Asia. As of September 2026 the Southeast Asia plan runs from $2.90 for 1 GB / 7 days up to $17.01 for 10 GB / 30 days, and the wider Asia plan starts at $5.34 for 1 GB / 7 days. Single-country plans start lower: Thailand and Vietnam both at $0.87 for 100 MB / 7 days, with 1 GB / 7 days at $1.41 in Thailand and $1.62 in Vietnam.

The Head-to-Head Comparison Table

Here is a like-for-like view across the questions travellers ask before they buy. The Airalo and Holafly rows describe catalogue mechanics rather than prices, because a stale competitor figure next to our live one helps nobody. Our column comes from the live catalogue, checked September 2026.

Metered vs Unlimited: The Model That Matters Most

The biggest split between these three is metered data (Airalo, Monsoon Travellers) versus unlimited daily data (Holafly). Metered suits travellers who know roughly what they use. Maps, messaging, ride-hailing and a few photos usually land at 500 MB to 1 GB per day, which makes a 5 GB or 10 GB pot the natural fit, and unused data carries forward inside the validity window.

Unlimited daily plans earn their price when you stream video, tether a laptop or video-call home for long stretches, though "unlimited" often means unlimited at a reduced speed above a daily threshold, so check that the throttle floor is workable. The break-even sits around 1.5 GB to 2 GB of real use per day on a two-week trip: below that, metered tends to work out cheaper; above it, unlimited daily starts to make sense. Your last two months of home mobile data is a decent sanity check.

Coverage and Networks Across the Region

All three providers roam on local partner networks rather than running their own infrastructure, so the signal you get depends on the local carriers behind each plan, not the brand on the eSIM. Our Asia catalogue is built on the partner networks listed in our supplier's coverage data for each country. In Vietnam our plans roam on Viettel Mobile, Vinaphone, MobiFone and Vietnamobile, with 5G on Viettel Mobile and Vinaphone. In Thailand and Indonesia they roam on the mainstream local networks, Telkomsel among them. Airalo and Holafly publish their own per-product coverage details and also use local partners, so coverage in mainstream tourist zones is typically comparable across the three.

All three thin out in the same places, because the underlying carrier is the limit: remote Indonesian islands away from Bali and Java, the far-northern Vietnamese highlands around Ha Giang, altitude on the Annapurna and Everest trekking routes, and remote Maldivian atolls. Download offline maps for those legs whichever provider you buy.

Which Asia eSIM Should You Pick?

For most Asia trips we would pick a metered regional plan, and for a two-week Thailand-and-Vietnam route specifically we would buy our 5 GB Southeast Asia plan rather than stacking two Airalo country plans, because one profile carries you across the border and the total data pot lands cheaper. The caveat is real: if you stream or tether daily, Holafly's unlimited model is the calmer buy and we would tell you to take it. Here is how that resolves by trip shape.

Single-country trip, 7 to 14 days

A one-country trip matches a single-country plan most tightly. A Bangkok-and-Chiang-Mai loop matches the Thailand collection, a Bali stay the Indonesia collection, a Hanoi-to-Ho-Chi-Minh route the Vietnam collection. Airalo's single-country plans are the closest competing shape; Holafly's compete on convenience at a higher daily rate.

Multi-country Southeast Asia loop, 2 to 5 countries

For a loop touching Thailand, Vietnam, Indonesia, Malaysia, Singapore, Cambodia or the Philippines, a regional plan tends to beat stacking country plans. Our regional vs country comparison guide works through the maths: on a 3-country, 21-day trip, one regional plan is simpler and often cheaper than three country plans plus the friction of switching profiles at each border. Backpacking five countries in a month, buy the regional plan and top up if the first pot goes early. Airalo's regional plan is the same shape; Holafly's runs on the daily-unlimited model.

Longer route that adds South Asia

If your route adds India, Nepal, Sri Lanka or the Maldives to a Southeast Asia core, our wider Asia regional plan is the broadest single-profile option we sell, at $5.34 for 1 GB / 7 days (as of September 2026). Airalo's regional Asia plan is the closest competitor. On a trip this wide, watch the fair-use throttle on any daily-unlimited plan: a long trip spent throttled feels more expensive than the sticker suggests.

Streaming-heavy or laptop-tethered trip

For a three-week nomad stint in Chiang Mai or Da Nang with daily client calls, take an unlimited daily plan or size a metered plan at 20 GB / 30 days. This is the use case where we would not argue with a Holafly purchase. Our digital nomad guide covers the sizing, and our free AI travel planner Meili can draft the day-by-day itinerary around it.

Setup, Support and the Practical Bits

Installation is broadly similar across all three: buy the plan, receive a QR code, add the eSIM to your phone, enable data roaming on that line once you land. Airalo delivers through its mobile app; Holafly and Monsoon Travellers email the QR code. We send ours with step-by-step iPhone and Android instructions, so you can install on Wi-Fi at home a day or two before departure and switch the line on when you arrive. Our Asia eSIM setup guide walks through both platforms.

Monsoon Travellers support runs by email and we typically reply within the same working day; check each provider's support page for their response times. Most first-connection problems clear with a restart, a check that the eSIM is set as your mobile data line, and a check that roaming is on for it. All three need an eSIM-compatible, carrier-unlocked phone, and our Asia eSIM compatibility checklist covers the mainstream models.

Airalo vs Holafly vs Monsoon Travellers FAQ

Which is cheaper for a 7-day Thailand trip: Airalo, Holafly or Monsoon Travellers?

It depends on your data volume, but a light-use week is typically most affordable on a metered plan from Monsoon Travellers or Airalo. Our Thailand plans start at $0.87 for 100 MB / 7 days and $1.41 for 1 GB / 7 days (September 2026). Holafly's unlimited daily model runs higher on the sticker for a single week but removes the cap anxiety. Compare the tier that matches your real data use, not the entry-level plan.

Can I use one eSIM across multiple Asian countries?

Yes, with a regional plan from any of the three providers. Monsoon Travellers sells a Southeast Asia regional plan covering seven countries and a wider Asia plan covering more of the region. Airalo sells an Asia regional plan on the metered model, Holafly on the daily-unlimited model. Pick the shape that matches your data habits.

What if I run out of data mid-trip?

Every provider supports top-ups, but the mechanics differ. With Monsoon Travellers you buy a top-up in the same collection you originally bought from, and your existing eSIM keeps working with the new allowance. Airalo tops up inside its app. Holafly's daily-window model means you extend the window rather than adding a data pot.

Do these eSIMs give me calls, SMS or a local number?

No, all three are data-only. None provide a local number, calls or SMS in the destination country. Your own number stays reachable: an eSIM runs alongside your existing SIM on a dual-SIM phone, so calls and two-factor authentication texts still arrive while the travel eSIM handles data. WhatsApp, Messenger and FaceTime work over the eSIM's connection.

Whether you are booking a single-country week in Thailand, a Southeast Asia loop, or a longer route that adds South Asia, the right eSIM comes down to your data habits and your route shape. Monsoon Travellers is built specifically for Asia, with a tighter catalogue and regional plans designed around how travellers move through the region, while Airalo and Holafly optimise for global breadth.
