How does Simbye eSIM work for Vietnam?
Set it up before you fly
The link and QR code arrive by email. Install the eSIM at home on Wi-Fi – one tap or one scan is enough. You never type in an APN, and no time is running yet.
Switch it on after landing
Whether you arrive at Noi Bai in Hanoi, Tan Son Nhat in Ho Chi Minh City, Da Nang, Cam Ranh near Nha Trang or Phu Quoc: pick the eSIM as your data line, turn on data roaming, done. You walk straight past the SIM counter.
Get moving and top up
Now the validity starts. Grab, Maps and your messenger work right away, and you can share the hotspot with a laptop or a travel partner. Running low? Top up on the road.
Check Device Compatibility
Make sure your device supports eSIM before purchasing
Which networks will you be on in Vietnam?
You set nothing up – after landing the eSIM picks between Viettel and Vinaphone on its own.

| Networks | Download | Upload | Latency |

Two networks are enabled on this eSIM: Viettel and Vinaphone. You don't pick one. After landing the eSIM connects on its own and switches while you travel if the other network is stronger. Viettel is the country's largest operator and carries furthest into the provinces, Vinaphone is strongest in the cities and along the coast. If nothing appears after you switch on: turn on data roaming, then flight mode off and on once. You never have to type in an APN. Worth knowing if your phone is older: Vietnam is switching off 2G completely from 15 September 2026, so your handset should support 4G. 3G is set to run until 2028.
In Hanoi, Ho Chi Minh City, Da Nang, Hue, Hoi An, Nha Trang, Da Lat and Can Tho, 4G is everywhere and the big cities also have 5G – but the national 5G rollout is still far from finished and does not reach every province. Along the coastal route, in Ninh Binh, across the Mekong Delta and on Phu Quoc you'll get through fine. It thins out in the mountains and on the water: on the Ha Giang Loop, on the passes around Sapa, inside the caves at Phong Nha and on boats in Ha Long and Lan Ha Bay, signal can disappear for hours. Download maps, tickets and translations offline before you go.
eSIM or a local SIM card in Vietnam?
Vietnam splits by what you need: the eSIM is ready before you land and asks for no ID, while a local SIM means a shop photographing your passport — but it brings the +84 number that Zalo and MoMo want.
| Feature | Local SIM card | |
|---|---|---|
| Registration | None. You buy and activate online, no ID needed. | ID required since 2016. The shop photographs your passport and registers the card to you. |
| When you're online | Right after landing, as soon as you switch your phone on. | Only after a counter or shop visit, often waiting in line in the arrivals hall. |
| Where you buy it | Online from home, the QR code arrives by email before you fly. | At an airport counter or a Viettel, Vinaphone or MobiFone shop in town. |
| Payment | With your own card in your own currency, before the trip. | Cash in dong. Airport prices are usually higher than in a city shop. |
| Phone number | None. Data only, no calls or SMS over the network. | Comes with a Vietnamese +84 number, which you need for Zalo, MoMo or a local bank SMS. |
| Your home number | Stays reachable – the eSIM runs alongside your normal SIM. | Has to come out of the phone while the local card is in. |
| Topping up | Online anytime, no shop visit, no language barrier. | Top-up card at a kiosk, and the top-up menus are often Vietnamese only. |
| If something goes wrong | Email support in English or German. | Back to the shop you bought it from – which by then is usually hundreds of kilometres away. |
For most travelers the eSIM is the simpler choice: set up before departure, no queuing on arrival.

Frequently Asked Questions about Vietnam eSIM
Data, calls, real phone numbers, top-ups and setup — everything you need to know before you buy a Simbye eSIM.
You can buy an eSIM for Vietnam online, before you fly – right here on this page. An eSIM for Vietnam is a digital SIM card built into your phone. You buy the plan, get the QR code by email and scan it at home on Wi-Fi. That means no counter in Vietnam, neither at Noi Bai in Hanoi nor at Tan Son Nhat in Ho Chi Minh City.
Yes, eSIMs actually work in Vietnam. Vietnam does not ban eSIMs from foreign providers. Your phone needs eSIM support and must not be carrier-locked – that covers iPhones from the XS on, Google Pixel from the 4 on and most Samsung models from the S20 on.
The Vietnam eSIM uses Viettel and Vinaphone. The eSIM picks whichever is stronger where you are and switches while you travel. The plan is valid in Vietnam only – for Cambodia, Laos or Thailand you'll need a separate plan or a regional Asia plan.
No, you don't need your passport in Vietnam. The ID requirement applies to SIM cards bought inside Vietnam: the shop photographs your passport and registers the card in your name. You buy our eSIM online beforehand, with no ID and no registration anywhere.
No, there is no Vietnamese phone number. This is a data-only plan with no phone number and no calls or SMS over the network. Zalo, MoMo and OTP messages from a Vietnamese bank all need a +84 number, and that only comes with a local SIM card.
How much data you need for Vietnam depends on use: 1 GB packages cover maps, Grab, messengers and bookings. If you watch video on the road, upload photos to the cloud or share a hotspot with a laptop, 20 GB or an unlimited plan suits you better. You can top up at any time, so you don't have to commit up front.
Yes, one more thing to do online before arrival: the digital arrival card. Vietnam introduced it in 2026: you fill it in online beforehand and show a QR code at passport control, now at several airports including Ho Chi Minh City, Hanoi, Da Nang and Phu Quoc. It can only be submitted shortly before arrival and has nothing to do with the eSIM – just do it on Wi-Fi before you fly.
An eSIM for Vietnam starts at 1,95€; the exact price depends on the data volume and validity you choose, and the table above on this page shows each Vietnam plan with its figure. A week in Hanoi and Ha Long needs far less than a month riding through the country on maps and hotspot. You pay once at checkout, with no contract.
The eSIM that's best for Vietnam depends on how far you travel. This line reads Viettel and Vinaphone, and your phone switches between them by itself: Viettel goes furthest into the provinces, Vinaphone is strong in the cities and along the coast. 4G is everywhere in Hanoi, Da Nang and Ho Chi Minh City, while 5G is not finished nationwide. One catch: Vietnam is switching off 2G, so your handset needs 4G.
