Land at Tan Son Nhat in Ho Chi Minh City or Noi Bai in Hanoi, and the first thing you'll want is data. Vietnam runs on apps: Grab for rides and food, Google Maps for the Old Quarter's tangle of streets, and translation tools for menus written only in Vietnamese.

Your Vietnam eSIM connects to 4 mobile networks, automatically switching to the strongest signal — with speeds up to 5G.
A Vietnam eSIM from Lumbus gets you connected before you leave home. Buy online, then tap the install link in your email and your phone sets the eSIM up itself — or scan the QR code if you prefer. Do it before your flight, and when you land your phone connects on its own. No hunting for a SIM counter, no paperwork at a kiosk. Your home SIM stays in place for calls and texts, while local data handles everything from booking a GrabBike to finding the night market in Hoi An. Cafe Wi-Fi is common in Vietnam, but the moments you really need data happen on the move.
The real networks your Lumbus eSIM connects to in Vietnam.
Your Vietnam eSIM connects to local networks: Viettel Mobile and Vinaphone on 5G, plus MobiFone and Vietnamobile on 4G. You don't pick one — your phone latches onto the strongest signal automatically, from a rooftop cafe in Ho Chi Minh City to a beach in Da Nang. Top speed is 5G on supported devices, so streaming and video calls feel like home.

Practical advice for using mobile data in Vietnam.
Grab is how you get around Vietnamese cities — motorbike taxis, cars, food delivery. Set up your account at home, then book a ride straight from arrivals.
Riding the Ha Giang Loop or trekking around Sapa? Download offline Google Maps before leaving Hanoi, so a fork in a mountain road never leaves you guessing.
Zalo is Vietnam's go-to messaging app. Homestay hosts, tour operators, and Hoi An tailors often prefer it to email, making bookings and pickup times easier to confirm.
Turn on your phone's hotspot so the whole family can browse from the boat deck. One eSIM for Vietnam keeps tablets and laptops online between kayak stops.
The north-south railway from Hanoi to Ho Chi Minh City takes over a day. Download shows on hotel Wi-Fi and save your data for maps and messages.
