Viettel eSIM: A Great Choice for Tourists in Vietnam
For travelers visiting Vietnam, a Viettel eSIM is one of the best options for reliable mobile connectivity throughout the country. Viettel is Vietnam’s largest mobile network operator and is widely recognized for its extensive network coverage, making it particularly useful for travelers visiting not only major cities such as Hanoi, Ho Chi Minh City, and Da Nang, but also rural areas, beaches, and popular tourist destinations.
A Viettel eSIM gives travelers convenient access to mobile data without having to purchase or replace a physical SIM card. After purchasing the eSIM, travelers can install it using a QR code and keep their Primary SIM active on a compatible, unlocked smartphone. This makes it easier to receive important calls, text messages, and OTP verification codes while using Viettel for everyday data.
For tourists, mobile data is essential for Google Maps, Grab, WhatsApp, translation apps, social media, hotel bookings, and online payments. A Viettel eSIM can help travelers save money by avoiding expensive international roaming charges in Vietnam.
For visitors staying in Vietnam for 5–10 days or longer, Viettel eSIM is a practical combination of wide coverage, convenient activation, and affordable travel connectivity.

Why Choose a Viettel eSIM for Vietnam?
Among Vietnam's major mobile networks, Viettel is one of the strongest choices for tourists who want a combination of wide coverage, fast mobile data, easy eSIM installation, and affordable pricing.
The Viettel eSIM available from Vietnam eSIM is designed for international travelers who want to connect to Viettel's network without purchasing a physical SIM card after arriving in Vietnam.
1. Wide Network Coverage
One of the most important factors when choosing a Vietnam eSIM is network coverage.
Vietnam is more than Hanoi and Ho Chi Minh City. Many travelers visit Ha Long Bay, Ninh Binh, Sapa, Ha Giang, Da Nang, Hoi An, Phu Quoc, Mui Ne, and other destinations where reliable connectivity can be especially important.
Viettel has a large nationwide network covering major cities as well as many rural, mountainous, coastal, and island areas. Viettel's own reporting highlights its extensive 4G and 5G network deployment across Vietnam.
For travelers planning to explore beyond Vietnam's major cities, network coverage can therefore be just as important as the price of the eSIM.
Best for: Travelers visiting multiple destinations, road-tripping, exploring rural areas, or traveling to mountainous regions.
2. Fast 4G and 5G Mobile Data
A travel eSIM should provide enough speed for everyday activities without constantly searching for Wi-Fi.
A Viettel eSIM can be used for:
- Google Maps and navigation
- Grab and other ride-hailing apps
- WhatsApp and Messenger
- Google Translate
- Social media
- Online banking
- Hotel and flight bookings
- YouTube and music streaming
- Sharing photos and videos
- Mobile hotspots and tethering
Viettel has also expanded its 5G network in Vietnam. The company states that its 5G service can deliver substantially higher speeds than 4G in suitable coverage areas.
Actual speeds will vary depending on your location, device, network conditions, and whether 4G or 5G is available.
3. 5GB of Data Every Day
For travelers who use their phone regularly, having a daily data allowance is more convenient than buying a very small fixed-data package.
Our Viettel tourist eSIM currently provides 5GB of data per day, with the daily allowance resetting at 23:59 Vietnam time (GMT+7).
This gives travelers plenty of data for normal travel activities such as navigation, messaging, browsing, translation, social media, and ride-hailing.
How much data do you need in Vietnam?
| Traveler type | Recommended usage |
|---|---|
| Light user | Maps, messages, occasional browsing |
| Typical traveler | Maps, Grab, social media, translation |
| Heavy user | Video, photo uploads, frequent social media |
| 5GB/day plan | Suitable for most travelers |
4. Flexible 7–30 Day Plans
Different travelers need different amounts of connectivity. A weekend trip requires a different plan from a month-long Vietnam adventure.
| Viettel eSIM | Validity | Data | Price |
|---|---|---|---|
| Viettel 7-Day | 7 days | 5GB/day | $8.00 |
| Viettel 10-Day | 10 days | 5GB/day | $9.90 |
| Viettel 15-Day | 15 days | 5GB/day | $11.90 |
| Viettel 20-Day | 20 days | 5GB/day | $14.90 |
| Viettel 30-Day | 30 days | 5GB/day | $16.90 |
Which plan should you choose?
- 7 days: Ideal for a short vacation or city break.
- 10 days: A good choice for a Hanoi–Ha Long Bay–Ninh Binh itinerary or similar trip.
- 15 days: Suitable for travelers visiting several regions of Vietnam.
- 20 days: Recommended for longer holidays and multi-city itineraries.
- 30 days: Best for travelers spending a month in Vietnam or combining work and travel.
5. Affordable Alternative to International Roaming
International roaming can be convenient, but depending on your home carrier and plan, roaming charges may be significantly higher than purchasing a local Vietnam travel eSIM.
- A prepaid Viettel eSIM lets you know the cost before your trip.
- For example, the current 7-day plan is $8, while the 30-day plan is $16.90, with 5GB of data available each day.
- For travelers who need mobile data every day, this predictable prepaid pricing can be easier to budget than paying unexpected roaming charges.
Viettel eSIM For Tourist
The difference between eSIM and regular SIM cards
Regular SIM card
A regular SIM card is a small plastic card that stores contact information such as name, phone number, subscriber identification, etc. It is the first generation of SIM cards, consisting of plastic and a copper core containing integrated circuits and processing chips that store information.
eSIM Card
On the other hand, eSIM is an electronic SIM card that can replace the traditional physical SIM card. These SIM cards are directly soldered onto the device's electronic circuit and have a compact size while providing full functionality. eSIM allows customers to switch to different networks through software without the need for complex physical removal and installation.
