Buy eSIM data plans for Vietnam
Your Vietnam eSIM is a prepaid data plan that connects your phone to local Vietnam networks at full speed the moment you land — a digital SIM you install before you fly, with no queues, no SIM swap and no roaming fees.
A Vietnam eSIM is a data-only plan that loads onto your phone before you fly, so there is nothing physical to swap. Touching down at Hanoi's Noi Bai International Airport, you skip the SIM kiosks and step into the terminal already connected. Your plan connects to local networks MobiFone (4G) and Viettel (5G), so you can pull up maps, message home, and call a ride before your luggage reaches the carousel. There are no roaming fees and no waiting in line, just mobile data the moment you land.

Frequently asked questions
Which mobile networks does the Vietnam eSIM use?
Your Vietnam eSIM connects to local networks, including MobiFone on 4G and Viettel on 5G. It selects the available network for you automatically, so you get a fast, reliable signal in the cities without changing any settings.
Will I have coverage travelling the full length of the country?
If you are travelling from north to south, expect strong coverage in the cities and along busier routes. On long rural stretches between destinations the signal can be variable, so download maps and key information ahead of time for those quieter sections.
Will my data work on a boat trip out on the water?
On trips out onto the water, such as around Ha Long Bay, the signal can drop out once you are away from the shore. Plan for this by sending messages and downloading anything you need while you are still on land, then reconnect when you return to the coast.
I am visiting several countries in the region. Is this the right plan?
This is a Vietnam-only plan, made for trips that stay inside the country. If your itinerary covers several countries across Southeast Asia, choose a regional eSIM instead so you stay connected as you cross each border.
When should I set up the eSIM before arriving in Vietnam?
Install the eSIM while you still have Wi-Fi at home, then leave it ready to switch on. That way it activates as you arrive at Hanoi's Noi Bai International Airport and you are online the moment you reach the terminal, with no scrambling for a signal after a long flight.
Can I keep my own number and use a hotspot in Vietnam?
Yes. The eSIM runs alongside your regular SIM, so your usual number stays active for calls and texts while the eSIM handles data. You can also turn on your phone's hotspot to share the connection with a laptop or a travel companion's device.
