How much is a Vietnam eSIM for one or two weeks?
Cafe wifi is everywhere in the cities, but your own data matters for Grab, Google Translate and getting between Hanoi, Hoi An and the south. The cheapest plan here that covers each trip.

Travelling in Vietnam: what to know
Three networks, one eSIM
The eSIM can use Viettel and Vinaphone, both with 5G, and MobiFone. Your phone joins whichever is strongest, which helps on long bus and train journeys between Hanoi, Hoi An and Ho Chi Minh City.
Mountains and bays
Signal can thin out on mountain roads in the far north and on boat trips in Ha Long Bay once you are away from the shore. Download offline maps, tickets and bookings before those days.
Data only, no Vietnamese number
There is no Vietnamese number on the eSIM and no ordinary calls or texts. Ride apps and others that sign you in by text message send the code to the number on your account, so keep your home SIM switched on with its Data Roaming off.
Show all 5Show fewer
Landing in Hanoi or Ho Chi Minh City
Turn off airplane mode, switch the eSIM line on, turn Data Roaming on for it and choose it for mobile data. It usually connects within a few minutes. If it does not, restart the phone rather than deleting the eSIM.
Unlimited for a long trip
For three weeks from north to south, Endless gives you a fresh block of full speed data every day for one trip price. At 1GB a day it keeps going at 1 Mbps after the day's full speed data.
Vietnam eSIM FAQ
How much is a Vietnam eSIM for a week?
Standard use, about 1GB a day, costs US$16.70 on the 10GB, 30 day plan; light use (300MB a day) US$6.90 (3GB, 15 days) and heavy use (2GB a day) US$26.40 (Endless, 2GB a day).
How much is a Vietnam eSIM for two weeks?
Standard use, about 1GB a day, costs US$28.90 on the 20GB, 30 day plan; light use (300MB a day) US$10.10 (5GB, 30 days) and heavy use (2GB a day) US$50.80 (Endless, 2GB a day).
Does the Vietnam eSIM have 5G?
Yes, on Viettel Mobile and Vinaphone; MobiFone (4G) does not. Your phone picks the strongest signal where you are.
Which networks does the Vietnam eSIM use?
It connects to Viettel Mobile (5G), MobiFone (4G) and Vinaphone (5G), and the eSIM uses whichever of them has the best signal where you are.
Which regional eSIM also covers Vietnam?
Three regional eSIMs cover Vietnam as well: the South East Asia eSIM from US$4.20 (up to 8 countries), the Asia eSIM from US$4.10 (up to 20 countries) and the Global eSIM from US$18.20 (up to 129 countries). Each covers several countries on one plan, handy if the trip also takes in Indonesia or Thailand.
Can I share the Vietnam eSIM data by hotspot?
Yes, on the daily plans, from US$3.20 a day; hotspot use counts toward the same daily allowance.
When do the days start on the Vietnam eSIM?
On first connection in Vietnam, not at purchase or install. Install it on wifi before you fly, up to 180 days after buying. The 100MB (7 days) plan is an exception: its validity starts the moment you install it, not on first connection, so install it only when you are ready to start using the data.
Can I make calls with the Vietnam eSIM?
No, it is data only, with no Vietnam number: WhatsApp and FaceTime calls work over the data.
Where does the Vietnam eSIM connect to the internet from?
From Hong Kong or Singapore, so apps may see you there rather than in Vietnam, which mostly matters to banking and streaming.
What is the best eSIM for Vietnam?
One that connects on landing and fits your data use. The RoamMore Vietnam eSIM roams on Viettel and Vinaphone with 5G and on MobiFone, installs at home before you fly, and only starts counting days once it connects in Vietnam. For 10 days most travellers need 5GB or 10GB.
Does the Vietnam eSIM work on Viettel?
Yes. It can use Viettel and Vinaphone, both with 5G, and MobiFone, and your phone connects to whichever is strongest where you are.
How much data do I need for three weeks in Vietnam?
About 6GB for maps and messaging, about 21GB with social media and video calls, and 42GB or more if you stream or hotspot a laptop. The 10GB plan valid 30 days covers light use; with social media and video calls take the 50GB plan valid 180 days, or a daily plan.
Do I get a Vietnamese phone number with the eSIM?
No. The eSIM is data only: no Vietnamese number, and no ordinary calls or texts. Calls work over the data through WhatsApp, FaceTime or Messenger, and your home number stays on your own SIM.
Can I use Grab in Vietnam with the eSIM?
Yes. Grab works on the eSIM data connection. If it sends a sign in code by text, the code goes to the number on your account, so keep your home SIM switched on with its Data Roaming off.
Heading somewhere else?
One eSIM can cover a whole region, handy for multi-country trips.
