Prepaid Data Plans for Vietnam
esimbloom lists 15 prepaid eSIM plans for Vietnam from $0.72 (the smallest is 100MB for 7 days). Every plan is data-only — mobile internet for maps, messaging and bookings, but no local phone number or SMS — and prepaid: pay once, no contract, no roaming charges.
You buy the plan, receive a QR code by email within minutes, and scan it to install the eSIM profile on your phone. The data allowance activates when you connect to a mobile network in Vietnam. Once active, you can check your remaining balance in your device settings or through the carrier's app if provided.
How to Set Up Your Vietnam eSIM
Before you travel, confirm your phone is eSIM-compatible and unlocked. Most iPhones from XS onward, recent Samsung Galaxy and Google Pixel models, and many other flagships support eSIM. Purchase your plan on the esimbloom website, and the QR code will arrive by email. Install the eSIM profile by scanning the code in your phone's settings—this step works over Wi-Fi and can be done before departure.
When you land in Vietnam, turn on data roaming for the eSIM line. The plan activates automatically when it registers on a local network. If you carry a second SIM, set the eSIM as your data line and keep your home SIM for calls and texts. You can switch between plans or remove the profile anytime in your device settings.
Staying Connected While Traveling in Vietnam
Mobile coverage across Vietnam is strong in cities like Hanoi, Ho Chi Minh City, Da Nang, and Hoi An, and extends reliably along coastal routes and the main north-south highway. Expect steady connectivity in Hạ Long Bay town, Huế, Nha Trang, and Dalat. In more remote areas—northern mountain provinces near Sapa, the central highlands around Pleiku, or the Mekong Delta's smaller waterways—coverage becomes patchy, though towns and main roads generally hold a signal.
Travelers typically use data for Grab or Gojek ride-hailing, Google Maps, Zalo (the dominant local messaging app), and WhatsApp. Streaming video or uploading high-resolution photos from Phong Nha caves or the rice terraces will drain data quickly; download offline maps and media over Wi-Fi to stretch your allowance. If you are island-hopping to Phú Quốc or Côn Đảo, coverage is available in populated areas, but snorkeling and jungle trails may leave you offline.
Frequently asked questions
How much does an eSIM for Vietnam cost?
esimbloom Vietnam eSIM plans start at $0.72, with 15 plans to choose from. You pay once for the plan you pick — no roaming fees and no contract.
Do I need an eSIM for Vietnam?
Only if you want mobile data without roaming charges. An esimbloom Vietnam eSIM is installed from a QR code before you fly, activates on your first connection in Vietnam, and is data-only — your home SIM stays in the second slot for calls and SMS, with its data roaming switched off.
Do Vietnam eSIM plans include a local phone number?
No. All Vietnam eSIM plans are data-only. You get mobile internet for apps and browsing, but no phone number for voice calls or SMS. Use WhatsApp, Zalo, or similar apps for communication.
When does my Vietnam eSIM plan start?
The validity period starts when the eSIM first connects to a mobile network in Vietnam. Installing the QR code before your trip does not activate the plan—it only becomes active after you land and turn on data.
Can I use my Vietnam eSIM in Cambodia or Laos?
No. These plans are valid only within Vietnam. If you cross into Cambodia, Laos, or Thailand, you will need a separate eSIM plan for that country or a regional plan that explicitly covers multiple destinations.
Will my eSIM work in rural Vietnam or on Ha Giang Loop?
Coverage in remote northern mountains and rural highland areas is limited. Towns along the Ha Giang Loop and major routes usually have signal, but expect gaps on mountain passes and in valleys between settlements.
How do I check my remaining data balance in Vietnam?
Check your device's cellular settings for data usage. Some plans include a carrier app or USSD code for balance inquiries. If your plan does not provide one, monitor usage manually in your phone's data settings.
