What is the best eSIM for Vietnam?

The strongest travel eSIM for Vietnam is whichever brand rides Viettel, MobiFone or VinaPhone with the broadest verified coverage for your route, honest fair use terms, working hotspot, and a clean onboarding flow that spares you the at-counter passport and face check. Vietnam's market is overwhelmingly state-owned: the three giants held roughly 98 per cent of subscribers in 2023, with army-run Viettel alone near 57.6 per cent. Vietnam joins no regional roaming union, so a local plan does not extend to Cambodia, Laos or Thailand. Coverage is strongest around Hanoi, Ho Chi Minh City and Da Nang. Weigh the brands in the ranking below.

The ranking

Travel eSIM ranking for Vietnam

We grade each brand on how far it reaches, how fast it runs, how steady it stays, which Vietnamese carrier carries it, how openly it states unlimited and fair use limits, how cleanly its onboarding handles the passport and face-scan rules, and what reviewers report. Independent throughout, and never for sale.

Local networks

Which local network does each travel eSIM use in Vietnam?

A travel eSIM brand sells the plan; a Vietnamese carrier carries the signal. Whichever national network a brand rides is what fixes your real-world coverage, your reach beyond the big cities, and whether 5G appears. The grid further down maps each brand to its host carrier in Vietnam.

Vietnam's mobile market is overwhelmingly state-owned. The runaway leader is Viettel, not a listed telco but a military enterprise run by the Vietnam Ministry of National Defence; it switched on nationwide 4G on 18 April 2017 claiming up to 95 per cent population coverage, made Vietnam's first official 5G connection on 10 May 2019, and held roughly 57.6 per cent of the market in 2023. Behind it sit two more government-owned carriers: MobiFone, the country's first GSM operator (founded 16 April 1993, Hanoi based) on about 22.52 per cent and moved under the Ministry of Public Security on 2 February 2025; and VinaPhone, the mobile arm of state group VNPT since 26 June 1996, on about 17.49 per cent. Those three together controlled almost 98 per cent of subscribers, leaving only the privately backed challenger Vietnamobile, a Hanoi Telecom and Hutchison Asia Telecom joint venture, on about 1.75 per cent. Most travel eSIMs sold for Vietnam host on one of the three state giants. Sources [1] [2] [3] [4] [5].

ID and SIM registration

Does Vietnam require ID to register a SIM? (KYC)

Whether you must show identity papers comes from national law, not from the eSIM brand. Here is the verified position for Vietnam.

Yes, Vietnam mandates SIM registration, and the bar has just risen. Until 2017 it was a buy-and-go market, but Decree 49/2017/ND-CP, issued on 24 April 2017, required every subscriber to record accurate identity details before activation; for foreigners that means presenting a valid, unexpired passport, whose number is bound to the SIM at the point of sale. From 15 April 2026, Circular 08/2026/TT-BKHCN (issued 31 March 2026) adds facial-biometric authentication on top of the paper check: a subscriber supplies their name, date of birth, national identification number and a face scan, verified through the state VNeID app or the operator, with service liable to suspension until the biometric step is done. Oversight has also shifted: the former Ministry of Information and Communications was folded into the Ministry of Science and Technology on 1 March 2025, so that is the ministry now answering for SIM rules. With a travel eSIM bought before departure, the brand handles any identity step inside its own checkout, which is the cleaner route past an airport-kiosk passport and face check, subject to each brand's onboarding terms.

Region context

How Vietnam compares to its Southeast Asian neighbours

Vietnam runs down the eastern edge of mainland Southeast Asia, sharing land borders with China to the north and Laos and Cambodia to the west, with a long South China Sea coastline.

Unlike the European Union's "Roam Like At Home" zone, mainland Southeast Asia has no shared roaming union, so a Vietnamese plan does not give you home-rate data the moment you cross into Cambodia or Laos; each country is a separate roaming jurisdiction with its own charges, and a multi-country regional eSIM usually suits a wider tour better. The deeper regional contrast is structural rather than legal: where many neighbours field private or foreign-owned carriers competing head to head, Vietnam's field is dominated by three state-owned operators, with the largest, Viettel, run by the armed forces, an arrangement with few parallels nearby. On registration, Vietnam sits among the stricter markets, pairing a passport rule with a 2026 face-scan requirement. Coverage is densest around Hanoi, Ho Chi Minh City and Da Nang, while the central highlands, remote reaches of the Mekong Delta and offshore islands such as Phu Quoc and the Con Dao group are where reach and speeds vary most. The local currency is the Vietnamese dong (VND ₫). Sources [1] [2] [7].
Plans by brand

Travel eSIM plans for Vietnam, by brand

The full grid of every brand and plan offered for Vietnam, with data, validity, price, host network, hotspot, KYC and top-up. Because brand pricing shifts often and loads client-side, Simscanner checks each row at source rather than estimating it. Every cell sits in a pending state until that check is done.

No invented prices. Simscanner will not print a plan price, data amount, validity or fair use cap it has not confirmed at the brand. Each field below holds at pending until a real source backs it.

FAQ

Frequently asked questions about Vietnam eSIMs

Straight answers to what Vietnam-bound travellers ask most. The wording lives in the page itself so both search engines and AI readers can lift it.

Do I need my passport to get a SIM card in Vietnam?

Yes, for a local prepaid SIM. Since Decree 49/2017/ND-CP took effect on 24 April 2017, every subscriber must register with identity details, and foreigners specifically must present a valid, unexpired passport, whose number is tied to the SIM at the counter. A travel eSIM bought from an international provider before you fly usually avoids the in-person registration step, but check the provider's own terms.

What is the face-scan rule that started in April 2026?

Under Circular 08/2026/TT-BKHCN, in force from 15 April 2026, new SIM and device registrations require facial-biometric authentication in addition to ID details such as name, date of birth and national identification number, verified through the state VNeID app or the operator, with service liable to suspension until the biometric step is completed. Pre-buying a travel eSIM abroad is the simplest way to sidestep an at-counter face check, subject to the provider's terms.

Will a Vietnamese SIM work in Cambodia, Laos or Thailand?

Not at local rates. Mainland Southeast Asia has no shared roaming union comparable to the EU's "Roam Like At Home", so a Vietnam plan is domestic and would incur international roaming charges, or simply not work, once you cross a border. If you are touring several countries, a multi-country regional eSIM is usually the better fit. Specific roaming terms vary by plan and remain pending verification here.

Which local networks do Vietnam eSIMs use?

The three state-owned operators that carry almost the whole market are Viettel, MobiFone and VinaPhone, with Vietnamobile a small fourth. Viettel reports the widest reach, having claimed up to 95 per cent population coverage at its 2017 4G launch, and it made Vietnam's first 5G connection in 2019. Coverage is strongest around Hanoi, Ho Chi Minh City and Da Nang. The local networks table on this page maps each brand to its Vietnamese carrier once that mapping is verified.

Is there 5G coverage for eSIMs in Vietnam?

5G depends on the Vietnamese network the eSIM rides and whether the plan includes it. Viettel made Vietnam's first official 5G connection on 10 May 2019, and the state carriers have built out service since, with the densest coverage around Hanoi, Ho Chi Minh City and Da Nang. Simscanner does not yet publish a verified per-brand 5G figure for Vietnam; the speed section fills in once verified.

How do I activate an eSIM before arriving in Vietnam?

Buy the plan, then install the eSIM over home Wi-Fi by scanning its QR code or using one-tap install. Leave it set to start on first contact with a Vietnamese network, switch data roaming on for that line, and make it your data line as you land at Noi Bai or Tan Son Nhat. Exact prompts differ by brand and device.
