1 How to Get Internet in Vietnam
There are three main ways to stay online during your trip:
- Local SIM card – Cheap and fast, but requires buying at a store or airport.
- Pocket Wi-Fi – Great for sharing data with others, but you’ll need to carry and charge it.
- eSIM – 100% digital, instantly activated, and ideal for modern travelers.
For most people, the eSIM is now the easiest and most flexible choice. You can buy it before you fly, activate it when you land, and enjoy local data rates without roaming fees.
2. Vietnam’s Main Mobile Networks
Vietnam’s mobile coverage is strong and affordable. The country’s major telecom providers include Viettel, Vinaphone, Mobifone, and Vietnamobile.
Among these, Viettel stands out with the most extensive nationwide coverage — from Hanoi and Ho Chi Minh City to smaller towns. Vinaphone is also excellent in urban areas, offering fast speeds and consistent service. Mobifone is a budget-friendly choice, though its signal can be weaker in rural regions. Vietnamobile is the cheapest, but coverage is limited mainly to big cities.
When you buy a Vietnam eSIM from a trusted provider, you’ll usually connect automatically to Viettel or Vinaphone, ensuring strong and stable service throughout your trip.
3. Why eSIMs Are the Smart Choice for Travelers
Here’s why more travelers are switching to eSIMs:
- Instant setup: Purchase your plan online and activate it with a quick QR code scan.
- No physical card: There’s nothing to insert, remove, or lose.
- Keep your original number: You can still receive texts or calls from your home SIM while using data from your eSIM.
- Affordable local rates: Avoid expensive roaming fees by using local Vietnamese networks.
- Eco-friendly: No plastic, no waste — just a digital connection.
With an eSIM, your internet starts working the moment your plane lands. It’s that simple.

4. How to Set Up an eSIM for Vietnam
Setting up your eSIM takes just a few minutes:
- Buy your plan online from your provider.
- Receive a QR code by email instantly.
- Scan the code using your phone’s camera.
- Activate mobile data once you arrive in Vietnam.
You’ll be online before you even clear customs.
5. Physical SIM Cards – Still an Option
If you prefer a traditional SIM card, you can buy one at Vietnam’s major airports or telecom stores. Staff usually speak basic English and can help install it.
However, SIM counters can get crowded, and swapping cards means losing access to your home number — one reason why eSIMs are now more popular with travelers.
6. Data Speed and Coverage
Vietnam’s 4G and 5G networks are well-developed. You’ll enjoy high-speed connections in all major cities, tourist areas, and even many rural regions.
In cities like Hanoi, Ho Chi Minh City, Da Nang, and Nha Trang, download speeds are typically fast and consistent. Viettel and Vinaphone networks are known for excellent reliability, especially when streaming, using maps, or making video calls.
7. Choosing the Right Plan
Every traveler’s needs are different. Short-term visitors might only need a few gigabytes of data for a week, while digital nomads may prefer monthly plans.
Before buying, consider:
- How long you’ll stay in Vietnam
- How much data you typically use per day
- Whether you’ll travel to nearby countries (if yes, consider an Asia-wide eSIM plan)
Simple eSIM offers plans such as 1GB for 7 days, 5GB for 30 days, or 50GB for 180 days, with prices starting around $6–65 USD.
8. Quick Tips for Travelers
- Always check your phone’s eSIM compatibility before purchasing.
- Keep a copy of your eSIM QR code in case you delete the profile by mistake.
- Use data saver mode or download maps offline to reduce usage.
Conclusion
For most travelers, an eSIM is now the easiest and smartest way to stay connected in Vietnam. It’s fast, affordable, and saves you the hassle of finding a SIM store or dealing with physical cards.
If you want the best coverage and speeds, look for an eSIM that connects to Viettel or Vinaphone, the country’s most reliable networks.
Whether you’re here for a weekend trip or a month-long adventure, setting up your eSIM before departure ensures that you’ll land in Vietnam ready to navigate, translate, and share — instantly.
