Vietnam SIM & eSIM 2026: Viettel, VinaPhone, MobiFone
Compare Vietnam tourist SIMs and eSIMs: Viettel, VinaPhone, MobiFone, verified plan examples, passport registration, coverage and eSIMfo data options.
In this article
You land in Hanoi, need a ride to the hotel and see several SIM counters promising large data allowances. Which one is actually right for your trip? Start with two questions: do you need a Vietnamese phone number, and where will you travel? The operator name alone does not answer either.
Viettel, VinaPhone and MobiFone operate local networks. A travel eSIM is a different purchasing route: you buy a package from a travel provider, then connect through the network named in that package. Here is how to compare both fairly.
- Need ordinary local calls? Compare a registered local SIM/eSIM with included domestic minutes.
- Need maps, messaging and mobile internet prepared before departure? Compare travel data eSIMs, including eSIMfo.
- Heading into mountains or onto a boat? Check your actual route and download essentials offline before leaving the city.
Viettel, VinaPhone or MobiFone: what is the difference?
Viettel
Viettel offers tourist SIM/eSIM options and publishes a 5GB-per-day example for a 30-day visit. Its official guide directs visitors to airport counters, official shops and authorised sellers. Compare the exact package code and SIM charge, rather than assuming every Viettel-branded offer has identical terms.
VinaPhone / VNPT
VinaPhone is VNPT’s mobile brand. Distinguish buying a local VinaPhone subscription from buying a travel eSIM that lists VNPT as its partner network. These can use the same mobile infrastructure while providing different quotas, activation rules, support and phone-number features.
MobiFone
MobiFone’s Hi Vietnam service is designed for international visitors and combines eSIM registration with tourist packages. Its official table includes total data allowances and domestic call minutes. Other MobiFone travel promotions exist; an offer from a different registration channel should not be mixed into the Hi Vietnam package conditions.
What do official tourist packages cost?
| Provider / package | Data and validity | Published package price | Important detail |
|---|---|---|---|
| Viettel 5G150T | 5GB/day · 30 days | 150,000 VND | SIM charge excluded; official tourist guide example |
| MobiFone Hi Vietnam HVN7 | 50GB total · 7 days | 120,000 VND | 70 domestic call minutes listed |
| MobiFone Hi Vietnam HVN15 | 120GB total · 15 days | 160,000 VND | 150 domestic call minutes listed |
| VinaPhone tourist option | Confirm current offer at official shop | Current quote required | Do not treat the archived 2019 offer as a 2026 price |
These are published examples checked on 8 November 2026, not identical products or guaranteed checkout totals. Viettel’s cited guide is dated 20 November 2025. Confirm eligibility, availability, tax treatment and any SIM or activation charge before paying.
The widely repeated 199,000 VND VinaPhone tourist price comes from a 2019 VNPT article. We have not presented that historical figure as a current tariff. Prices stay in their original currencies to avoid hiding exchange-rate and card-fee differences.
Where should you buy, and what documents are needed?
For a local subscription, take your original passport and use the operator’s official channel. Viettel’s tourist registration flow requests passport and portrait images. MobiFone’s Hi Vietnam instructions include passport-based eKYC, video verification and an electronic signature. Check the current flow for your nationality and arrival situation.
An airport counter is useful when you want assistance immediately; a city shop may suit you if you already have a working connection. Before leaving either, test mobile data with Wi-Fi switched off. Keep the receipt and package name; a large handwritten GB figure is not a complete tariff.
- Ask whether the allowance resets daily or is shared across the entire trip.
- Confirm whether you receive a local number, calls and SMS, or data only.
- Ask when validity starts and how to check remaining data or renew.
- Check the final price including the SIM and setup, and have the line registered to you.
Which network is best for your Vietnam route?
For Hanoi, Da Nang, Hoi An and Ho Chi Minh City, compare the operator named in the actual package with your accommodation and activities. For Sapa, Ha Giang, long rural transfers or island trips, route-level coverage matters more than a nationwide speed headline. A strong city result cannot prove reception in a mountain valley.
There is no honest universal winner for every hotel, road and device. Use current coverage maps as a starting point and ask your accommodation about the specific area. 5G also depends on your handset variant, package, roaming agreement and location; an eSIM does not automatically guarantee 5G everywhere.
Crowdsourced maps show recorded measurements, so empty areas may mean missing measurements rather than proof of no service. Save hotel addresses, tickets and maps offline, especially before a Ha Long boat trip or a mountain transfer.

Where does eSIMfo fit in the comparison?
The eSIMfo Vietnam page currently lists VNPT and 4G/5G coverage. The examples below are data packages, not Vietnamese voice subscriptions. Hotspot sharing is supported, so a tablet or travel companion can use your phone’s connection while nearby.
Choose the product by duration and data needs. A local tourist bundle can offer more gigabytes for the price; eSIMfo is an alternative for travellers who value buying and preparing their data package online before the flight. We do not label every eSIMfo option cheaper than every local offer.
| eSIMfo package | Validity | Displayed EUR price |
|---|---|---|
| 1GB total | 7 days | €3.40 |
| 5GB total | 30 days | €8.90 |
| 10GB total | 30 days | €14.85 |
Prices checked on 8 November 2026. The country page also offers other fixed-data and unlimited options. For unlimited plans, read the selected plan’s high-speed allowance and fair-use conditions; unlimited volume and unlimited full speed are different promises.
Daily data or total data: which allowance should you choose?
A 5GB-per-day plan gives a new daily allowance; it should not be treated as a freely usable 150GB pool. A 50GB total plan lets you spread the quota over its validity, subject to its terms. Neither label alone tells you what happens after the allowance is used.
As a planning example, 300MB per day for ten days is about 3GB; adding a 2GB buffer gives a 5GB budget. Video calls, cloud backups, hotspot users and streaming can increase this sharply. Check your own phone’s recent usage, download media on Wi-Fi and choose enough validity to cover the departure day.
How do you prepare your phone before arrival?
- Confirm your exact phone model supports eSIM and is unlocked for other networks.
- Install over reliable Wi-Fi following your provider’s instructions. Check whether validity begins at installation, activation or first network connection.
- Label the lines clearly. Select the Vietnam eSIM for mobile data and disable automatic data switching to your home line.
- Enable data roaming on the travel eSIM only if its instructions require it; keep home-line data roaming off. Voice calls and SMS on your home line follow your home carrier’s tariff.
- After landing, turn on the installed line and test a map or web page. Follow the local operator’s activation steps if you purchased a local subscription.
If it does not connect, check the selected data line, remaining allowance, package validity and the supplied APN. Briefly toggle airplane mode. Contact support before deleting the eSIM, because reinstalling may require a replacement profile.
Vietnam SIM and eSIM: frequently asked questions
Which eSIM has the best coverage in Vietnam?
Compare the network in the specific package with your route. eSIMfo currently lists VNPT; Viettel and MobiFone have their own local offers. No national ranking guarantees service on every mountain road, island or inside every building.
Can a tourist buy a Viettel or MobiFone eSIM?
Both publish options for international visitors. Use the official tourist channel and complete its identity checks. MobiFone Hi Vietnam describes passport eKYC and video verification; confirm the package’s current availability and activation process.
Do I need a Vietnamese number for Grab or WhatsApp?
A data eSIM does not supply a local number. WhatsApp can continue with your existing account. Set up and verify travel apps before leaving home when possible; receiving an OTP still requires access to the number registered with that service. Choose a local voice package if you need ordinary Vietnamese calls.
Can I buy a Vietnam eSIM before flying?
Travel eSIMs can be purchased online before departure. Install using reliable Wi-Fi and check the validity-start rule first. Some local-operator registrations have identity or arrival conditions, so follow the selected channel’s instructions.
Can I share my Vietnam eSIM through hotspot?
Yes, eSIMfo packages support hotspot. Shared devices use the same data allowance and drain the host phone’s battery faster. For local-operator offers, confirm tethering and any high-speed limits in that exact package.
Is an unlimited Vietnam eSIM better than 5GB or 10GB?
It depends on usage. Fixed-data plans can suit maps and messaging; video-heavy or shared use needs a larger budget. Check fair-use rules, high-speed limits, validity and the price for your actual trip, rather than choosing on the word unlimited alone.
