eSIM for Vietnam: your questions
How much does an eSIM for Vietnam cost?
Plans for Vietnam start at £2.49 for 0.49 GB · 1 day. There are 13 plans to choose from, valid from 1 day to 30 days.
What is the best Vietnam eSIM for a one-week trip?
For 7 days in Vietnam, the best value is 3 GB · 7 days at £3.99: enough for maps, messaging, ride apps and social media. If you stream, make video calls or work online, take 10 GB · 30 days for £9.49.
Which eSIM should I get for two weeks in Vietnam?
For 14 days in Vietnam, the best value is 5 GB · 15 days at £5.99: enough for maps, messaging, ride apps and social media. If you stream, make video calls or work online, take 20 GB · 30 days for £16.99.
Is there 5G in Vietnam?
Yes, in major cities. Elsewhere in Vietnam you get 4G/LTE, which is fast enough for maps, video calls and streaming. Your eSIM uses 4G/LTE, and 5G where the partner network allows it.
Do WhatsApp and FaceTime calls work in Vietnam?
Yes. Voice and video calls on WhatsApp, FaceTime, Telegram and similar apps work normally over the eSIM data in Vietnam.
Do I need to register a SIM or show my passport in Vietnam?
No. Your eSIM is bought online and needs no passport check or registration in Vietnam. A local SIM card, by contrast, requires your passport at a shop.
Will my eSIM work as soon as I land at Hanoi Noi Bai (HAN)?
Yes. Install the eSIM at home, switch it on when you land at Hanoi Noi Bai (HAN), Ho Chi Minh City Tan Son Nhat (SGN), and Da Nang (DAD), and it connects to a local network within a minute or two. You can order a ride or message your hotel before you leave the airport.
Where does the eSIM work in Vietnam?
Coverage is strong in Hà Nội, Hồ Chí Minh City, Đà Nẵng, and Hội An and along main roads. Signal can be weak or absent in remote areas such as Hà Giang loop and Sa Pa trails: download offline maps before you go.
Which apps are useful for travelling in Vietnam?
Travellers in Vietnam commonly use Grab, Be, Xanh SM, and Zalo. They all work over the eSIM data. Sign up and receive any SMS verification codes before you travel, as the eSIM has no phone number.
Can I use the same eSIM in Vietnam and nearby countries?
Yes. Regional plans (Sea, Asia Pacific, and Global Lite) cover Vietnam and other countries on one eSIM, so you do not need a new one at each border.
Which mobile networks does the eSIM use in Vietnam?
The eSIM connects to Vinaphone Vietnam and Viettel Vietnam and switches to the best available network automatically.
How much data do I need for a week in Vietnam?
For maps, messaging and social media, 1 to 3 GB per week is usually enough. If you make video calls, stream or work online, choose 5 GB or more, or an unlimited plan.
Can I buy my Vietnam eSIM before I travel?
Yes, and it is the best option: install it at home over Wi-Fi. The plan only starts when your phone first connects to a network in Vietnam.
Will WhatsApp still work with my usual number?
Yes. WhatsApp stays linked to your number. Keep your regular SIM on for calls and SMS if you want, and use the eSIM for data.
