See the plansWhy an eSIM for Vietnam
Vietnam is a long, thin country, and the classic trip runs its whole length: Hanoi and Ha Long in the north, Hue and Hoi An in the middle, Ho Chi Minh City and the Mekong in the south. An eSIM is what carries you the entire way on one plan, live for maps, Grab, and translation the moment you land, with nothing to change as you work down the map.
Getting around runs on Grab, for rides and even food, so staying online matters. You buy the data before you fly, pay from your crypto balance with no ID, and keep your home number on its own SIM. Data here is famously cheap and fast, so a bigger plan costs very little.
- One plan covers the whole country, Hanoi to the Mekong.
- Rides and food run on Grab, so being online matters.
- Connect on arrival at Hanoi, Ho Chi Minh City, or Da Nang.
- Pay in crypto with no ID, and keep your home number.
Is a Vietnam eSIM right for you?
Whoever you are travelling as, the setup is the same: buy, scan, connect. Here is what it means for you.
Vietnam eSIM vs a Vietnamese SIM vs roaming
Vietnamese SIMs are cheap, but you queue at a counter and hand over your passport. Here is how the options compare for a north-to-south trip.
SimVala eSIM

Vietnamese SIMs are inexpensive, but the airport queue and passport registration are the catch. Costs are rough guides, not quotes.
Coverage and networks in Vietnam
Depending on the plan, your eSIM connects to a major Vietnamese network such as Viettel, Vinaphone, or Mobifone. Coverage across Hanoi, Ho Chi Minh City, Da Nang, and the tourist regions is fast and cheap, and Viettel reaches the furthest into the mountains and countryside.
Expect strong eSIM coverage in Ho Chi Minh City, Hanoi, Da Nang, with data across the rest of Vietnam. Signal follows the local network, so it is strongest in cities and along main routes.
Coverage by area
Fast, cheap coverage across Hanoi, Ho Chi Minh City, Da Nang, and the coastal resort towns, their centers, and main routes. This is where most of your data goes.
Good along the length of the country and the coastal road and rail linking the cities, so the classic overland trip stays connected.
Signal drops out on overnight Ha Long Bay cruises on the open water, and thins up in the Sapa and Ha Giang mountains. Download maps for those legs.
How much data do you need in Vietnam?
Whether your Vietnam trip is 7 days, 2 weeks, or a month, pick the data size to match. Not sure? Slide your trip length below and we will suggest a plan.
Vietnam travel leans on maps, Grab for rides and food, messaging, and a stream of street-food and scenery photos to the cloud. For a one to two week north-to-south trip, 5 to 10 GB suits most people, and data is so cheap here that a bigger plan costs little. Top up any time.
Estimate your data for Vietnam
Social, photos, some video
An estimate to guide you, not a limit. Wi-Fi at your hotel covers a lot, and you can top up any time, so it is fine to start smaller.

Using an eSIM in Vietnam's top cities
One Vietnam eSIM covers all of these. Here is what to expect, city by city.
eSIM in Hanoi
Strong 4G and 5G through the chaotic Old Quarter, around Hoan Kiem Lake, and out toward the Ha Long transfers. Your eSIM keeps Google Maps, Grab, and translation live as you weave the motorbike-packed streets.
eSIM in Hoi An
Reliable across the lantern-lit ancient town, the tailor shops, and An Bang beach. Handy for booking the boat with the floating candles, finding cafes, and translating the menus in the old town.
eSIM in Ho Chi Minh City
Fast coverage across District 1, from the Ben Thanh Market to the rooftop bars, and out to the Cu Chi tunnels. Useful for Grab through the traffic, food delivery, and day trips into the Mekong Delta.
Yes, you can call and text in Vietnam
Your eSIM is internet. So every calling and messaging app works, just like at home. No new apps to learn, nothing to set up.
Message anyone
Zalo, WhatsApp, iMessage all run over your data.
Call home for free
Voice and video on WhatsApp, FaceTime, or Messenger, no call charges.
Need a real number?
A data eSIM has no number of its own. Add a virtual number for codes and a local line.

Good to know
- •One Vietnamese plan covers the whole country, so there is nothing to switch as you travel from Hanoi in the north to the Mekong in the south.
- •Coverage is strong and cheap in the cities and along the coast. It thins on overnight Ha Long Bay cruises out on the water and up in the far-north mountains around Sapa and Ha Giang.
- •Viettel reaches the furthest outside the main cities, so pick a Viettel-based plan if you are heading into the mountains.
- •The eSIM carries data. Keep your home SIM active for calls and bank codes.

Why travellers choose SimVala
“Hanoi to Saigon over three weeks on one eSIM, never swapped a thing. Grab for every ride and half my meals, so being online mattered. Paid in USDT, no ID.”
“Great everywhere in the cities. On the overnight Ha Long cruise the signal dropped out on the water, which the page warned about, so no surprise. Cheap top-ups in crypto.”
“Data was absurdly cheap and fast. Da Nang and Hoi An were flawless, thinner up in Sapa as noted. Kept my own number and just used this for data.”

If Vietnam is one stop of a bigger trip, one regional plan covers the whole area on a single eSIM.
eSIM in Vietnam: FAQ
Does my phone support eSIM?+
Most phones from the last few years do, including recent iPhone, Samsung Galaxy, and Google Pixel models.
How do I pay?+
In crypto only: Bitcoin, Monero, USDT, USDC, Solana, and more.
When does my plan start?+
Your plan validity begins when you install and activate the eSIM, not when you buy it.
Will an eSIM work in Vietnam?+
Yes, as long as your phone supports eSIM and is carrier unlocked. The eSIM connects to a local network in Vietnam and gives you data the moment you arrive.
How much data do I need in Vietnam?+
It depends on what you do. Maps and messaging use very little, while video and hotspotting use much more. For a typical one to two week trip, 3 to 5 GB suits most travelers, and you can top up any time.
Can I keep my phone number in Vietnam?+
Yes. Your home number stays on your physical SIM for calls and codes, while the eSIM carries local data. Both work at once on a dual-SIM phone.
Can I buy my eSIM before I travel?+
Yes, and you should. Buy and install it before you fly, then switch the line on when you land in Vietnam. Your plan's days only start counting when you activate it, not when you buy.
Does the plan expire?+
Each plan runs for a set number of days once you activate it, shown on the plan. Any balance you have not spent stays on your account for your next trip, so nothing is wasted.
Can I use my eSIM as a personal hotspot?+
On most plans, yes, so you can share your connection with a laptop or a friend. Tethering uses more data, so pick a larger plan if you rely on it.
Does one plan cover the whole north-to-south trip?+
Yes. A Vietnam plan works nationwide on one profile, so the same eSIM keeps you online in Hanoi, Hue, Hoi An, and Ho Chi Minh City, and everywhere along the way, with nothing to switch.
Will I have signal on a Ha Long Bay cruise?+
Near the harbour and the shore, usually yes. Out on the open water on an overnight cruise the signal drops, which is the nature of being at sea, not a SimVala limit. Download maps and anything you need before you sail.
Is mobile data cheap in Vietnam?+
Very. Vietnam has some of the cheapest, fastest mobile data in the region, so coverage is strong and great value, and a bigger plan costs very little.
Is there an unlimited data plan for Vietnam?+
Yes, an Unlimited 30-day plan, good for a longer trip or heavy use. Sized plans are the cheaper pick if you use less, and you can top up any time.
