Best eSIM for Vietnam in 2026: 6 Providers Compared (Real Prices)

Vietnam comes up almost as often as Thailand when friends ask me what to buy before a Southeast Asia trip — Hanoi's old quarter, Ha Long Bay, the overnight train down to Ho Chi Minh City, all of it needs decent data to actually navigate. I checked the live pricing from all 124 providers we track for Vietnam specifically, not a generic Southeast Asia rate, and did the math the same way I do for every destination before I recommend one.

The quick answer

• Cheapest unlimited data for a full month: Maya Mobile at $49.99 — no Vietnam-specific competitor comes close; the next cheapest is Ubigi at $54.90.
• Best short unlimited deal: eSIMCard's 5-day unlimited at $14.89 beats every other unlimited plan under two weeks, Nomad eSIM's $18.00 included.
• Cheapest possible entry point: eSIMCard's 1GB/3-day plan at $2.90 — just ahead of Saily's 1GB/7-day at $3.99, which trades a bit more money for over twice the validity.
• Notable standout: Ubigi sells a 240GB annual plan for $360.00 — a genuinely unusual option if you're relocating to Vietnam rather than just visiting.

What you'll actually pay: six providers compared

Airalo

Airalo has one of the deepest Vietnam lineups of the six, with real granularity between 3, 5, 7, 10, 15, and 30 days. A 1GB/3-day plan is $4.00, 3GB/7-days is $8.00, 10GB/7-days is $17.00, and the 30-day tiers run 5GB at $11.00 up through 50GB at $49.00. Unlimited tiers start at $11.50 for 3 days and reach $69.00 for a full month — on the pricier end of the unlimited comparison, but the fixed-data side is genuinely competitive. Real discount code active:

eSIMCard

eSIMCard is the real find in this comparison — a genuine 1-day unlimited plan at $3.84, and its 5-day unlimited at $14.89 undercuts every other short-trip unlimited option we track for Vietnam, Nomad eSIM's well-priced 5-day plan included. Its fixed-data side is sharp too: a 1GB/3-day plan at $2.90 is the cheapest entry point on this whole list, and 10GB/7-days runs $19.27. Its 30-day unlimited at $60.57 doesn't beat Maya Mobile or Ubigi at that specific duration, but for anything under two weeks it's the one to check first. Real discount code active:

Nomad eSIM

Nomad eSIM is still worth checking for shorter Vietnam trips, even though eSIMCard now beats it on 5-day unlimited pricing specifically. Its Unlimited 5-day plan is $18.00, and its fixed-data 30-day tiers are strong: 10GB is $17.00, 5GB is $10.00, 3GB is $8.00. There's no 7-day or 30-day unlimited option for Vietnam specifically, though — it jumps from 5 days straight to 10 days ($33.00), so plan around those exact windows. Real discount code active:

Nomad eSIM -15% ESIMKART15

15% off, single-use per customer. Excludes plans under $5, sale plans, add-on data, unlimited plans, and the Thailand 50GB plan.

Saily

Saily's 1GB/7-day plan at $3.99 is a close second on entry-level pricing — a little more than eSIMCard's 3-day equivalent, but with more than double the validity window, which makes it the better pick if you want a bit of breathing room rather than the absolute lowest price. Its unlimited plans run from $18.99 (5 days) to $59.99 (30 days), and the 30-day fixed-data tiers are reasonable across the board: 20GB at $28.99, 10GB at $17.99, 5GB at $10.99.

Ubigi

Ubigi's Vietnam fixed-data pricing rewards a closer look: 10GB for 30 days is $12.90, 20GB for 30 days is $16.00, both comfortably ahead of the equivalent Saily and Airalo tiers. Its unlimited 30-day plan at $54.90 is the second-cheapest we found, behind only Maya Mobile. The standout, though, is its annual plan — 240GB spread over 12 months for $360.00 — genuinely unusual among the six providers and worth knowing about if you're staying long-term rather than visiting for a couple of weeks.

Maya Mobile

Maya's flat global rate — $9.99 for 3 days, $19.99 for 7 days, $27.99 for 14 days, $49.99 for 30 days — is the best full-month unlimited deal in Vietnam. Its 30-day price beats Ubigi by around $5 and beats eSIMCard by over $10. The one place it doesn't win outright is against eSIMCard's cheaper 5-day plan, which works out ahead for a short trip.

Why the prices are all over the place

Same three pricing models as every other destination I've priced for this site. Maya charges the same flat rate everywhere it operates, which is why it comes out ahead here despite not specialising in Vietnam at all. Airalo, eSIMCard, Nomad eSIM, Saily, and Ubigi all mix fixed-data tiers with unlimited, so the "best" plan really does depend on how much data you'll use rather than which headline number looks lowest.

My honest take, the same one I give for Thailand: most people overestimate how much data a Vietnam trip actually needs. Grab, Google Maps, and messaging apps add up to far less than people assume — a 10GB plan from Ubigi or Saily covers a normal two-week trip for most travelers at a fraction of unlimited pricing. Our data usage guide breaks down the actual numbers if you want to check your own habits before deciding.

How to pick based on your trip

A short stop, light data use: eSIMCard's 1GB/3-day plan at $2.90 is the cheapest way in, or Saily's 1GB/7-day at $3.99 if you want more days to use it.

Around five days: eSIMCard's Unlimited 5-day plan at $14.89 is the best value we found at this length, ahead of Nomad eSIM's equivalent at $18.00.

A full month, fixed data is enough: Ubigi's 20GB/30-day plan at $16.00 is excellent value — most travelers don't come close to using 20GB in a normal month.

A full month, you want unlimited: Maya Mobile at $49.99, ahead of Ubigi ($54.90), eSIMCard ($60.57), Airalo ($69.00), and Saily ($59.99).

You're relocating or staying long-term: Ubigi's 240GB/12-month plan at $360.00 is a genuinely rare option among the providers we track.

A few things worth knowing before you buy

Hanoi, Ho Chi Minh City, Da Nang, and the other major tourist hubs all have strong, reliable coverage. More remote areas — up in the northern mountains around Sapa, for instance — can be patchier, which is true of local SIMs too, not just eSIMs.

Install before you fly. Every provider here lets you activate the eSIM only once you land, so there's no reason to hunt for airport wifi on arrival.

Check your phone is eSIM-compatible and carrier-unlocked first — our compatibility guide takes about a minute.

If this is your first time using an eSIM, our beginner's guide to how eSIMs work covers installation and activation from the very start.
