What the numbers mean
What Vietnam eSIM prices reveal
The market in Vietnam looks mid-market on entry price and much better on value. 300MB / 1 Day from Yesim is the cheapest buy in Vietnam at $0.51. In Vietnam, the same $0.51 reaches about 870MB at the $0.60/GB rate. Per-gigabyte pricing is set by Roamic at $0.60 for 50GB over 30 days. Between 10 providers there are 185 plans for Vietnam on file, 97 carrying an unlimited label.
The cheapest unlimited plan in Vietnam comes from Roamic at $1.83 a day. Daily demand above 3.0GB is what makes unlimited worth it in Vietnam, against $0.60/GB metered. Hotel Wi-Fi in Hanoi does most of the heavy lifting, which keeps metered plans cheap. ID rules apply to prepaid SIMs in Vietnam but not to travel eSIMs, which activate without paperwork.
Behind every eSIM for Vietnam sit Viettel, Vinaphone and Mobifone, all 5G. Expect between 15 and 250 Mbps in Vietnam, with the top of that range only on Viettel. Viettel posts the widest range, which is why plans riding it are the safer pick once your route leaves Hanoi. Vinaphone trails the field on range, which in Vietnam is only a problem off the beaten track. Crossing into Thailand is common, and no single plan covers both, so budget for a second plan or a regional one.

Before you buy
Things to know before buying an eSIM for Vietnam
-
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.
An eSIM for Vietnam is priced per country, not per city. One plan covers every network inside the borders, so there is no separate tariff for Hanoi, Ho Chi Minh City, Da Nang — and no airport counter to queue at either, because the profile is installed at home before you fly.
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. The destination-by-destination breakdown of all host carriers lives on the eSIM network map, and this destination has its own Vietnam carrier breakdown.

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 an eSIM for Vietnam
What is the cheapest eSIM for Vietnam?
Start with Yesim, whose 300MB / 1 Day is the cheapest Vietnam plan at $0.51. Roami sits next at $1.99, and the strongest per-gigabyte rate comes from Roamic's Vietnam eSIM 50GB / 30 Days at $0.60/GB. Check the validity window alongside the price, because a cheap plan that expires early is not cheap.
Is unlimited eSIM data in Vietnam actually unlimited?
'Unlimited' here means unlimited data, not unlimited speed: 97 Vietnam plans apply fair-use caps. Prices run $1.83 to $4.21 per day depending on duration, and Roamic is the cheapest at $1.83/day. Treat the published terms as the real limit: 3 GB/day, then 1 Mbps.
Airalo or Holafly for Vietnam?
Airalo and Holafly solve different problems, so compare the models before the prices. Airalo's strongest Vietnam offer is $0.98/GB, sold as Xin Chao - 50 GB for $49.00. Holafly's floor price for Vietnam is $11.90 over 3 days ($3.97/day), with no data counter to watch.
Do I need ID verification for an eSIM in Vietnam?
Yes, Vietnam registers every SIM against a passport and travel eSIMs are no exception, so expect a quick ID upload while you buy. It happens inside the provider's checkout rather than at a counter, and no Vietnamese address is needed. Viettel is the network most travel plans default to, which is also why they hold up on the Ha Long Bay and northern mountain routes.
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?
One country per plan, so an eSIM bought for Vietnam stops working at the border. A regional bundle or a second plan is the way to add Thailand, and both are worth pricing against simply buying two.
Can I use an eSIM in Vietnam?
Travel eSIMs are sold for Vietnam by every provider we track, and none of them needs a local address. Every one of the 10 providers here sells into Vietnam, which is itself the answer to whether eSIMs work there. The device check takes thirty seconds, and the plans above are all priced on one scale.
Will my phone work with an eSIM in Vietnam?
Compatibility is entirely about your device, and Vietnam adds no requirement of its own. None of the 10 providers here requires a particular handset, only that the device has the chip and is unlocked. Confirm the EID appears, then compare the plans above.
Do I need a local number in Vietnam?
Not for a visitor. A Vietnam eSIM gives you connectivity, and the number stays with your home line. The practical split is data on the eSIM and the existing number on the physical SIM, with roaming switched off on the home line. Use the eSIM for data and the home line for anything that needs the number.
What do travellers say about eSIMs in Vietnam?
No aggregate score from us. What this page offers instead is the arithmetic. The comparison above puts all 185 Vietnam plans from 10 providers through one formula, which no review site can claim. The measured comparison is above, and the opinions are best read where they were posted.
