Description
Vietnam is one of those countries where a working data plan changes the whole tempo of the trip — Grab bikes in Hanoi arrive in four minutes, Google Translate's camera mode decodes a Phở menu, and the sleeper-bus driver from Hội An to Nha Trang tells you via Zalo exactly where to stand at the pickup. A Blikst Vietnam eSIM runs on MobiFone, one of the country's three major carriers, at 3G / 4G speeds across all 63 provinces.
Where MobiFone works best
Ho Chi Minh City, Hanoi, Đà Nẵng, Hải Phòng, and Cần Thơ have blanket 4G. The coastal corridor from Đà Nẵng through Hội An and Nha Trang is strong. The Mekong Delta has solid 4G around Cần Thơ and most province capitals but thins on the smaller tributaries and island homestays near Bến Tre. Sapa and the Ha Giang Loop up in the far north have 4G in the main towns (Sapa, Hà Giang town, Đồng Văn) and 3G on the switchback passes — usable for maps, not for streaming. Ha Long Bay has signal near Bãi Cháy and on most cruise routes but expect dead zones inside the karst caves.
Cost vs. a local SIM
Vietnamese tourist SIMs are cheap and widely available at Tân Sơn Nhất (SGN), Nội Bài (HAN), and Đà Nẵng (DAD) airports — if you're prepared to deal with the kiosk markup and passport registration on arrival. The tradeoff: the eSIM loads before you fly and skips the jet-lagged haggling at the arrival hall. Home-carrier roaming for Vietnam is typically $10/day or punitive per-MB rates.
Airport arrival
Install the profile before you leave. SGN, HAN, and DAD all have Wi-Fi but it's captive-portal and slow at peak arrivals. The line activates once you're registered on MobiFone post-landing. If you're entering overland from Cambodia (Moc Bai), Laos (Lao Bao), or China (Dong Dang), expect a brief reconnection gap at the frontier.
Apps you'll use every day
- Grab: The default for taxis, bike rides, and food delivery. GrabBike is the fastest way through Saigon or Hanoi traffic. Runs on live GPS, so data is constant.
- Be: Vietnamese-owned ride-share alternative. Often cheaper than Grab at peak; coverage is strongest in HCMC and Hanoi.
- Zalo: Vietnam's dominant messaging app. Tour operators, homestay hosts, and even bus companies default to it. Install it if you're staying longer than a few days.
- Google Translate: Camera mode for menus is the single biggest data-to-experience multiplier. Download the Vietnamese offline pack as backup.
- 12Go and Baolau: For buying sleeper bus, train, and ferry tickets. Both work cleanly over 4G.
- Momo and VNPay: QR-code payments, dominant among locals. Tourists often can't sign up, but some markets and restaurants show only a Momo QR.
Ha Giang, Sapa, and the north
The Ha Giang Loop is one of Vietnam's best rides and one of the places your data will be most strained. Signal cuts out on the Ma Pi Leng Pass and in parts of the Dong Van Karst Plateau. Pre-download offline Google Maps of the whole loop before you leave Hà Giang town, and keep the homestay contacts saved offline. Sapa town has good signal; the trekking trails to Lao Chải and Tả Van villages have patchy 3G.
Plan sizing for typical trips
A weekend Hanoi or HCMC city break: 2 GB. One-week north-to-south fast hits (Hanoi → Ha Long → Hội An): 5 GB. Two-week classic route including Sapa or Ha Giang plus the coast: 10 GB. A full month backpacking or a Mekong slow-travel trip: 20 GB. Digital nomads in HCMC or Đà Nẵng working from cafés for a month should go 50 GB — Vietnamese café Wi-Fi is good but not a full-time substitute.
Install, fly into SGN, HAN, or DAD, and land with Grab and Google Translate already live. No SIM kiosk, no passport photocopy, just the ride into the city.

eSIM FAQ
An eSIM, or Embedded SIM, is a digital SIM that allows you to activate a mobile plan without using a physical SIM card. It is built directly into your smartphone, smartwatch, or tablet and provides the same functionality as a physical SIM. With eSIM, switching between carriers or adding a secondary number becomes seamless and hassle-free.
Getting an eSIM is simple! Check if your device supports eSIM technology. Then, purchase an eSIM plan from your preferred carrier or from our website. After purchase, you’ll receive a QR code or activation details to set up the eSIM on your device in minutes.
Most modern smartphones, including the latest iPhones, Samsung Galaxy models, and Google Pixel devices, are eSIM compatible. Check your device settings under “Cellular” or “Mobile Data” to see if eSIM options are available. Alternatively, refer to your device’s specifications or contact us for guidance.
The number of eSIMs you can have depends on your device. For example, most iPhones allow multiple eSIM profiles but only one active eSIM at a time. Some Android devices support dual-active eSIMs, giving you more flexibility. Check your device’s specifications for details.
Activating an eSIM involves a few easy steps: 1. Purchase an eSIM plan from our website or your carrier. 2. Scan the provided QR code using your device’s camera or enter the activation code manually. 3. Follow the on-screen instructions to add the eSIM profile to your device. Once activated, your eSIM is ready to use!
To activate an eSIM on iPhone: 1. Go to Settings > Cellular > Add Cellular Plan. 2. Scan the QR code from your eSIM provider or enter the activation details manually. 3. Choose your preferred settings for data, calls, and messaging, then tap Done. Your eSIM is now set up and ready to use.
Yes, eSIM offers several advantages over traditional SIM cards: Convenience: No physical SIM card required. Flexibility: Easily switch between carriers or plans. Space-saving: Frees up internal space in devices for additional features. Eco-friendly: Reduces plastic waste. Upgrade to eSIM and experience seamless connectivity like never before.
Unfortunately, it is not possible to transfer your eSIM using the same QR code, as QR codes can only be scanned once for security reasons. If you wish to use your eSIM on a new device, you will need to contact your carrier to request a new activation code or QR code. Once issued, you can set up the eSIM on your new device following the standard activation process.
