Airalo vs Holafly Vietnam 2026: Which eSIM Works

Airalo vs Holafly for Vietnam in 2026 comes down to how you use data: Airalo bills per gigabyte on the VNPT/Vinaphone network, Holafly bills per day for unlimited data on the same VNPT network, and Monsoon Travellers slots between them with capped plans such as 1 GB / 7 days for $1.58 (as of October 2026) for a light trip. This guide compares the two headline eSIM brands for a Vietnam trip against our own Vietnam catalogue, so you can pick a plan without paying for data you will not use.

Why this comparison exists

Airalo and Holafly are the two eSIM brands most travellers to Vietnam have already heard of. Airalo popularised the low-cost, data-capped model. Holafly runs the unlimited-daily model that heavy streamers gravitate toward. Both work in Vietnam, both ship a QR code within minutes of purchase, and both ride the same host network in Ho Chi Minh City, Hanoi, Da Nang and Hoi An.

At Monsoon Travellers we focus exclusively on Asia connectivity, with single-country eSIMs across our Asia catalogue plus two regional plans. So we can compare Airalo and Holafly against our own Vietnam range without pretending to be neutral, and without inventing numbers.

A quick scope note: this article covers each brand's Vietnam-only plans. If you are visiting Vietnam plus Thailand, Cambodia or Laos on the same trip, a Southeast Asia regional plan is a different calculation, and our regional vs country plan guide is the better starting point.

Airalo Vietnam: how "Xin Chao Mobile" bills

Airalo sells its Vietnam plans under the "Xin Chao Mobile" label, all riding the VNPT / Vinaphone network with 4G LTE coverage across major cities. The billing model is Airalo's global standard: you pay for a fixed data bucket over a fixed number of days, top up if you run out, and the SIM stops working when either the data or the days run out (whichever comes first).

Airalo's Vietnam range is priced per gigabyte with validity windows that stretch across a typical 1 to 4 week trip. Because Airalo's exact tiers and prices change with promotions and regional pricing, check the Airalo Vietnam page directly rather than trusting a number lifted from a comparison blog. The consistent point is the structure: capped GB, top-up if you run out, no unlimited option.

Airalo's advantages for a Vietnam trip are brand recognition and app polish. The eSIM installs cleanly from a QR code or from Airalo's app, balance is visible in the app, and support handles common activation edge cases well. The trade-off is that a moderate user tethering a laptop can burn through a mid-tier bucket before the validity ends, which forces a top-up at a higher effective price per gigabyte. Airalo does not list a Vietnam unlimited plan on that page.

Holafly Vietnam: unlimited data, day-by-day pricing

Holafly's Vietnam eSIM is unlimited data on the VNPT / Vinaphone network, sold in 3, 5, 7, 10, 15 and 30 day validity windows. We checked their public Vietnam page in August 2026 and captured the rack rate for each window:

Two honest reads. First, the per-day cost drops as the plan lengthens, which is a sensible discount, but even the 30-day window still lands at roughly $2.46 per day of coverage (at time of writing). Second, "unlimited" in Vietnam is real but shaped: Holafly's own page notes speed can throttle after heavy daily use, and coverage in remote mountain or jungle areas may be weaker than in urban Vietnam.

Monsoon Travellers Vietnam: capped plans, USD price per GB

We publish a capped-GB range for Vietnam that follows the same structure as Airalo: a fixed data bucket over a fixed number of days. Selected tiers, in USD:

The price per gigabyte falls as the bucket grows, so the 10 GB and 20 GB tiers suit longer or heavier trips. Monsoon does not sell a Vietnam unlimited plan; if a truly uncapped connection is a hard requirement, Holafly is the honest recommendation.

Side-by-side: Airalo vs Holafly vs Monsoon Travellers Vietnam

The headline comparison at the tier most travellers pick, around 5 GB for a 30-day window, is where the three-way choice sharpens.

How to size a Vietnam data plan honestly

Most travellers overbuy data for Vietnam. A typical 10-day itinerary of Ho Chi Minh City, Hoi An, Hue and Hanoi with Google Maps, Grab, messaging, a few social uploads and occasional video watching on hotel Wi-Fi lands around 3 to 6 GB. Heavy Instagram Reels or short-form video watching on mobile can push that to 8 to 10 GB. That is the difference between our 5 GB and 10 GB plans, both well under the price of an equivalent unlimited window.

Who genuinely needs unlimited data in Vietnam? Remote workers hosting daily video calls, content creators uploading raw footage, or long-stay digital nomads who tether a laptop as their only internet. For those users, Holafly's model earns its price. Our digital nomad guide for Asia works through the numbers.

Who does not need unlimited? Two-week backpackers, family holidays, cruise passengers dipping in and out of ports, and honeymooners who mostly want maps and messaging. Our Southeast Asia backpacking data guide profiles the light-use travellers we see most often.

A pragmatic sizing rule: estimate your usual daily mobile data at home in gigabytes, multiply by trip days, and round up 30 percent to cover extra maps and translation queries.

Coverage and network reality in Vietnam

Airalo, Holafly and Monsoon Travellers can all use VNPT / Vinaphone in Vietnam, so the network underneath is largely shared. The practical question is not "which brand covers Vietnam better?" but "where does VNPT cover Vietnam well, and where is coverage patchy?".

VNPT coverage is typically good across Ho Chi Minh City, Hanoi, Da Nang, Nha Trang, Hoi An, Hue, and the main tourist corridors including Ha Long Bay and the Mekong Delta hubs. Coverage thins out in remote mountain areas of the far north (Ha Giang loop, Sapa outskirts), in some parts of the central highlands, and on longer inter-city bus routes. Coverage and speeds may vary by location.

Because the network underneath is largely shared, the bigger practical difference is the billing model. Holafly's unlimited plans can slow after heavy daily use; capped-GB plans from Monsoon Travellers and Airalo stop when the bucket runs out, and you buy a top-up.

Verdict: which eSIM should you actually buy for Vietnam?

For a 1 to 2 week Vietnam trip with normal use, a capped 5 GB or 10 GB plan from Monsoon Travellers is our recommendation, at $5.45 or $9.57 (as of October 2026), a fraction of the price of Holafly's 7-day unlimited window. Pair that with hotel Wi-Fi in the evenings and it is more than enough for maps, Grab, messaging and moderate social use across Ho Chi Minh City, Hoi An and Hanoi.

Two honest exceptions where a competitor is the better choice:

• Buy Holafly if you truly need unlimited data (daily video calls, tethering a laptop as your only internet, streaming several hours a day). The unlimited price starts to make sense over roughly 20 GB a week.
• Buy Airalo if you already live in the Airalo app across many countries and value single-app management more than the price delta.

Skip: paying for an unlimited plan for a 5-day city break where you spend most nights on hotel Wi-Fi. The unlimited premium buys nothing you will use.

Alternatives worth a mention

Airalo and Holafly dominate the Vietnam eSIM conversation, but they are not the only options. Nomad and Saily (from the Nord Security group) also sell capped-GB Vietnam plans on a similar model to Airalo; check each provider's own page for current pricing.

None of these alternatives changes the core three-way logic: capped GB (Monsoon Travellers, Airalo, Nomad, Saily) versus unlimited daily (Holafly). Pick the model that matches your usage first, and only then compare price within that model. Confirm your phone supports eSIM (most iPhones from XS onward, most Google Pixel from 3 onward, and a growing list of Android flagships) and that it is carrier-unlocked.

Frequently Asked Questions

Does Airalo work in Vietnam?

Yes. Airalo's Vietnam plans (branded Xin Chao Mobile) run on the VNPT / Vinaphone network with 4G LTE coverage across major cities. Activation is by QR code or via the Airalo app, and on-network coverage is the same as any other VNPT-based eSIM.

Does Holafly work in Vietnam?

Yes. Holafly's Vietnam plans are unlimited-data eSIMs on the VNPT / Vinaphone network. Coverage is strong in cities and main tourist corridors, and Holafly notes on their own page that speed can throttle after heavy daily use and that remote mountain or jungle areas may see weaker service.

Is Airalo or Holafly cheaper for Vietnam?

Usually Airalo, unless you use a lot of data. Airalo sells capped data buckets, so a light or moderate user typically pays less than Holafly's unlimited-day rate. Above roughly 20 GB a week, Holafly's flat price starts to look competitive.

Which is best for streaming and video calls in Vietnam?

Holafly, if you truly stream heavily every day. For occasional video calls and light streaming on hotel Wi-Fi, a capped 10 GB plan from Monsoon Travellers at $9.57 (as of October 2026) is the more cost-efficient pick.

Does Monsoon Travellers use the same network as Airalo and Holafly?

Largely, yes. Our supplier's coverage data lists Vinaphone (VNPT) and Viettel Mobile for Monsoon Travellers Vietnam plans, so you share the VNPT network Airalo and Holafly use. The main differences are billing model (capped GB vs unlimited) and price.

Before you buy: cross-check the current tiers on your chosen provider's own page (Airalo and Holafly both refresh pricing periodically).
