Why do you need a SIM card in Vietnam?

Getting a SIM card is one of the best ways to stay connected, save money, and make your Vietnam tour more convenient. Mobile data in Vietnam is fast and affordable, allowing you to easily use Google Maps, Grab, and messaging apps without relying on unstable public Wi-Fi.

Vietnam also has widespread 4G and 5G coverage, ensuring a fast and stable connection even in rural areas. With a local SIM, you can avoid expensive international roaming fees, book transport, contact hotels, and communicate with locals easily via apps like Zalo or WhatsApp.

While free Wi-Fi is available in many cafes, hotels, and public spaces, it can often be slow and unreliable. A Vietnamese SIM card gives you more flexibility and ensures you’re always connected.

Top 3 mobile network providers in Vietnam

Vietnam has three major mobile operators that offer reliable coverage and affordable prepaid SIM card plans:

Viettel

Viettel is the largest mobile provider in Vietnam, offering excellent coverage even in remote areas. It’s a great choice for travelers planning to explore rural regions or off-the-beaten-path destinations. Viettel also provides fast 4G and 5G speeds, making it ideal for streaming, video calls, and online navigation.

Vinaphone

Vinaphone is known for its strong urban coverage and affordable prepaid plans. It offers reliable service in major cities like Hanoi, Ho Chi Minh City, and Da Nang, making it a solid choice for tourists staying in urban areas. Vinaphone often includes bonus data and free social media access in its SIM card packages.

Mobifone

Mobifone is one of the oldest mobile networks in Vietnam and provides consistent coverage and competitive data plans.

Where to buy a SIM card in Vietnam?

Getting a SIM card in Vietnam is easy and can be done in multiple locations. Here are the best places to buy one:

At the airport

Most international airports in Vietnam, including Noi Bai (Hanoi), Tan Son Nhat (Ho Chi Minh City), and Da Nang International Airport, have SIM card kiosks. While airport prices may be slightly higher than in the city, buying a SIM card upon arrival ensures you are connected as soon as you land. Staff at airport kiosks usually speak English and can help you set up your SIM card.

Official mobile stores

If you want the best deals and full access to different data plans, visit an official Viettel, Vinaphone, or Mobifone store in the city. These stores offer authentic SIM cards at standard prices and provide assistance with registration and activation. You must show your passport to purchase a SIM card in official stores.

Convenience stores

Popular convenience stores like Circle K, 7-Eleven, and VinMart often sell SIM cards. Buying from convenience stores is generally safe. You should avoid buying SIM cards from street vendors as there is some risk of buying an expired or inactive SIM card.

eSIM in Vietnam - The ultimate solution for travelers

While traditional physical SIM cards from local providers like Viettel, Vinaphone, and Mobifone have been the go-to option, eSIM technology is quickly becoming a more convenient alternative.

eSIM vs physical SIM - Which one is better?

Unlike a physical SIM, which requires purchasing and inserting a card into your phone, an eSIM allows instant activation by simply scanning a QR code. This means travelers can set up their mobile service before arriving in Vietnam, avoiding the hassle of finding a SIM card at the airport or local stores.

Additionally, eSIMs are more secure as they cannot be lost or damaged, unlike physical SIM cards. However, eSIM compatibility is limited to newer smartphones, so travelers should check if their device supports eSIM before choosing this option.

How to activate your Vietnam SIM card?

Activating a SIM card in Vietnam is usually simple, and most tourist SIMs come pre-activated. However, if activation is required, follow these steps:

1. Insert the SIM card into your unlocked phone.

2. Restart your device to allow the SIM to register on the network.

3. Dial a specific activation code (varies by provider) or follow the instructions given at the point of purchase.

4. To check your balance, dial *101# or use the provider’s mobile app.

5. Start using your data, calls, and texts!

If you have trouble activating your SIM, visit a mobile store for assistance.
