An eSIM for Vietnam is a digital data plan for the phone you already own. There is no physical SIM card, no airport lines, and no passport needed. Your plan is ready on your SIMAREA account before you even leave home.
It works safely alongside your normal SIM. You keep your own number for calls and important text messages. Your data goes through the SIMAREA plan. Just turn off data roaming on your home SIM to avoid high bills.
Every plan here uses more than one partner network. Your phone joins one when you arrive and can switch to another if the signal weakens.
If you stay longer, top up your current plan with more data. You do not need to buy a new one.
What it is not: a local phone number. If you need a number for verification codes, see virtual numbers.
Vietnam eSIM on Viettel, Vinaphone and MobiFone
5GOne eSIM that can use any of Vietnam's three networks, from Hanoi to the Mekong Delta. Install it at home; on all but the smallest plan, the days start at the first connection in Vietnam.
The unlimited plan is the day pass we feature for Vietnam: after its daily full-speed allowance it keeps you connected at a lower speed, and it is billed per day for the days you choose. Fixed plans are one price for the term shown. Nothing on this page is an estimate.
How to get mobile data in Vietnam
Install it at home before you go. Some plans here start counting at installation, so check the line under the price for the plan you pick.

What to know about an eSIM for Vietnam
The specifics that decide whether a travel eSIM is useful once you're actually there.
More than one network
Every plan here lists more than one partner network. If one gets weak, your phone can switch to another.
Set up before you go
No SIM card store, no passport check. Install it at home, then turn on data roaming for it when you arrive.
Hotspot sharing
Share your internet with a laptop or a friend, if your plan and phone allow it.
Keep your own number
The eSIM is just for internet. Your normal SIM still receives calls and important bank codes. You can use both at once.
Keep using the same eSIM
Staying longer? Top up the same plan with more data from your dashboard. No need for a new QR code.
If it does not work
Not installed or connected yet? Ask for a refund within 30 days of buying it. Installed but not working on any of its networks? Support helps, and refunds you if it cannot be fixed.
eSIM Vietnam: three networks on every plan
Each Vietnam plan sold here lists all three Vietnamese networks: Viettel Mobile, Vinaphone and MobiFone. Your phone registers on one and can move to another where the first is weak, which helps on a trip that runs from the northern highlands to the southern delta. To stay on one network, turn off automatic network selection and choose it in the phone's settings.
The catalog types all three networks as 5G. Every plan here includes 5G in its speed except the 15-day 3 GB plan, which runs on 4G/LTE and 3G. On the others you get 5G where the network has built it and 4G/LTE in the rest of the country.
Why every Vietnam plan shows a Hong Kong IP
The plans on this page connect to Vietnamese networks but hand your traffic to the internet in Hong Kong, so sites and apps see a Hong Kong IP address. Directions, chat apps and email don't care where that address is. A Vietnamese bank, an e-wallet or a streaming service that checks the country you connect from may treat it as a login from abroad.
No plan sold here exits in Vietnam. If you rely on a service that accepts only Vietnamese connections, use it over hotel or café Wi-Fi. The IP address of the plan you select is under Technical specs, and support answers 24/7 if you want to check a plan before paying.
Vietnam travel eSIM: matching a plan to the route
Fixed plans for Vietnam last 7, 15, 30 or 180 days and hold from 100 MB to 50 GB. The day pass lasts as many days as you choose.
A week in Hanoi and Ha Long Bay
Three plans cover a week: 100 MB, 500 MB and 1 GB. The 100 MB plan is the only one here that starts counting at installation; the rest wait for the first connection in Vietnam. If you send photos and make video calls every day, the 1 GB plan or the day pass leaves more room than the two small ones.
Two weeks from Hanoi to Ho Chi Minh City
The 15-day plans have 2 GB or 3 GB. A north-to-south route by sleeper train or domestic flights, with maps, ride-hailing and bookings open all day, can outgrow 2 GB. The 30-day plans of 3, 5, 10 or 20 GB give a longer window and more data, and any plan can be topped up on the same eSIM.
Six months in Da Nang or Saigon
One plan runs 180 days with 50 GB, the only size above 20 GB on this page. It fits a long stay for remote work or study; if the data runs out before the term does, add more instead of starting over. Sharing it with a laptop as a hotspot works if your plan and phone allow it.
Unlimited data in Vietnam: the day pass in numbers
If you searched for an "unlimited" Vietnam eSIM, the closest plan on this page is the day pass: 1 GB a day at full speed, then 1 Mbps for the rest of that day, and full speed again once the day resets. It uses the same three networks and the same Hong Kong exit as the fixed plans. You set the days in the picker, they start at the first connection in Vietnam, and the pass tops up if you extend your stay.
At 1 Mbps, maps, messages and booking a ride still work; video and large uploads slow down. If you'd rather have one big pool for the whole trip, the 30-day 20 GB plan or the 180-day 50 GB plan does that instead.
Vietnam with Cambodia, Laos or Thailand
A Vietnam plan has no network once you cross into Cambodia or Laos. For a route through more of Southeast Asia, two wider plans include Vietnam:
- Asia eSIM: every Asia plan includes Vietnam, and with it Thailand, Malaysia, Singapore and Indonesia. Cambodia and Laos are each on some Asia lists and not on others. In Vietnam these plans use MobiFone and Vietnamobile, plus Viettel Mobile on some lists; none of them uses Vinaphone.
- Global 130: every plan includes Vietnam, Cambodia and Thailand, with terms up to 365 days. In Vietnam it connects to MobiFone or Vietnamobile on 4G/LTE, and traffic exits in the UK or Norway.
Select a plan on those pages and its Coverage row under Plan details lists every country it includes. For a side trip to one country, Cambodia, Laos and Thailand have their own plans.
Vietnam eSIM: common questions
Which Vietnamese network will my phone use?
Whichever of the three it finds with a usable signal: Viettel Mobile, Vinaphone and MobiFone are listed on every plan sold here. You don't have to choose one before the trip, and we don't rank them. If you prefer one, select it by hand in the phone's network settings once you're in Vietnam.
Does a Vietnam eSIM include a Vietnamese phone number?
No. The eSIM is data only, so there's no +84 number and no calls or SMS on it; your own SIM keeps your number. Rented numbers are on the virtual numbers page, in the countries listed there, and Vietnam isn't among them today.
Does it work on Phu Quoc and in Sa Pa?
Yes. A Vietnam plan isn't split by region, so islands and mountain towns are included, and you have data wherever Viettel Mobile, Vinaphone or MobiFone has signal. With three networks on the plan, your phone has more than one to try away from the cities.
How much data do I need for two weeks in Vietnam?
With maps, messages and ride-hailing most days, the 15-day plans of 2 GB or 3 GB are the place to start. If you post photos and make video calls daily, compare the 30-day 5 GB and 10 GB plans, or the day pass with its fresh gigabyte each day. For your own estimate, the data calculator adds up the apps you expect to use.
Can I buy the eSIM before my Vietnam visa is approved?
Yes. Buying doesn't start the clock: on every plan except the 7-day 100 MB, the days start at the first connection in Vietnam. If the trip might fall through, leave the eSIM uninstalled, because only an eSIM that hasn't been installed or connected can be refunded, on request, within 30 days of purchase.
Is the 15-day 3 GB plan different from the others?
In one way: the catalog lists its speed as 3G/4G, so it stays on 4G/LTE where the other Vietnam plans can use 5G. Networks, Hong Kong exit and top-ups are the same. If 5G matters to you for a two-week trip, the 15-day 2 GB plan or a 30-day plan includes it.
Can I stay connected for longer than six months?
The longest Vietnam plan is 180 days with 50 GB, and you can top it up with more data or days on the same eSIM. For a year that also takes in other countries, the Global 130 eSIM has a 365-day plan with 1 GB for the whole term.
