What the numbers mean
What Vietnam eSIM prices reveal
Vietnam’s eSIM market splits cleanly into two pricing models. Metered plans — Roami down to $2.99 for 1GB — charge for a data bucket, while Holafly sells a single shape: unlimited data billed at roughly $3.43/day. On pure $/GB, Roami wins outright: 50GB / 30 Days works out to $0.62/GB, the best rate of the 51 plans we track.
The crossover point decides it. At $3.43/day, two weeks of Holafly runs $32+, while a 20GB bucket from the same table covers a heavy two-week trip for less. Light users — maps, messaging, the odd lookup — can stop at a 3-5GB bucket and stay in single digits. Rule of thumb for Vietnam: under a week and Wi-Fi at the hotel, buy the smallest bucket; remote work or hotspot sharing pushes every metered plan toward the unlimited tier.
Network-wise, Vietnam runs on Viettel, Vinaphone, Mobifone — coverage differences between them matter more than price differences between providers. Vietnam requires passport registration for every SIM including eSIMs. Check the fair-use column before buying any ‘unlimited’ label, and re-check this page before your trip: prices move.

Before you buy
Things to know before buying a Vietnam eSIM
-
Vietnam requires passport registration for every SIM including eSIMs - expect a quick ID upload during purchase.
-
Viettel is the only network that reliably covers Ha Long Bay and northern mountain routes; most travel eSIMs default to it.
Networks
Which networks do Vietnam eSIMs run on
Every eSIM connects to a local carrier network. Coverage, speed and rural reach follow that host network — so knowing whose mast your plan uses matters more than the brand on the voucher.
Viettel
5GTypical 20–250 Mbps — enough for HD streaming · video calls · navigation
Vietnam's largest — the best coverage beyond Hanoi and Ho Chi Minh City, including Ha Long Bay.
Vinaphone
5GTypical 15–200 Mbps — enough for HD streaming · video calls · navigation
Strong in the cities with good value.
Mobifone
5GTypical 15–200 Mbps — enough for HD streaming · video calls · navigation
Solid national coverage at budget prices.

We're mapping which eSIM brands ride which of these networks — until then, pick by coverage where you're going.
Which national networks cover Vietnam's major cities
All the carriers above serve these metros with full speed; the differences between them show up outside them — rural roads, mountain areas, islands and deep-indoor spots like basements and metro platforms.
Speeds are typical real-world downloads (4G floor to good 5G); actual speeds depend on device, plan and location. For context: Netflix 4K needs about 25 Mbps, HD about 5.

FAQ
What should I know before buying a Vietnam eSIM
What is the cheapest eSIM for Vietnam?
Roami - the 1GB / 7 Days at $2.99 ($0.43/day) is the cheapest plan we track. That buys 1GB over 7 days: enough for maps and messaging if your hotel has Wi-Fi.
Is unlimited eSIM data in Vietnam actually unlimited?
Not quite. All 10 'unlimited' plans here apply fair-use policies - the cheapest, Roami at $15.99 ($2.28/day), carries: Soft cap 2GB/day at full speed, then throttled. Treat them as big-but-capped plans and compare the caps.
Airalo or Holafly for Vietnam?
Different animals. Airalo sells metered buckets - its best rate here is competitive per GB - while Holafly only sells unlimited-by-day ($3.43/day at its cheapest tier). Short light trip: Airalo-style buckets win. Heavy data or hotspot sharing: Holafly's flat rate caps your downside.
Do I need ID verification for a Vietnam eSIM?
Yes. Local law requires passport-linked registration even for travel eSIMs, but the big providers verify in-app in a couple of minutes.
Which networks do Vietnam eSIMs use?
Plans on this page run on Viettel, Vinaphone, Mobifone. Differences matter mostly outside the big cities - the network column in the main table shows which carrier each plan rides.
Can one eSIM cover Vietnam and Thailand?
Regional Asia/continental plans from Airalo and Nomad bundle Vietnam with neighbors - usually worse $/GB than single-country plans, but cheaper than two separate eSIMs. For a two-country trip, compare one regional plan against two country-specific ones in the tables before buying.
