How to use Green SM (Xanh SM) in Vietnam: a first-timer's guide

If you've read older guides to Vietnam, they all say the same thing: download Grab. In 2026 I'd tell you something different. The app I use myself, and the one I put my travellers in, is Green SM, which you'll still hear called by its old name, Xanh SM. The cars are new and electric, the fares are shown before you book, and the driver usually phones a minute before arriving to confirm where you are. Here's how to set it up, pay safely, and find your car at the airport.

What is Green SM, and is it the same as Green SM?

Green SM is a ride-hailing and taxi company that uses only electric VinFast vehicles. It launched in 2023, is owned by Vingroup, Vietnam's biggest private company, and has grown into one of the largest ride services in the country. Until April 2026 it was called Xanh SM. It then renamed itself Green SM so it could use one name in every country it runs in, from Vietnam to Laos and Indonesia. "Xanh" simply means green in Vietnamese, so you'll hear locals use both names.

You can book three types of ride:

• Green SM Car: a 4-seat electric sedan. The everyday choice for one to three people.
• 7-seat car: a larger electric SUV for four or more, or for a group with luggage and paddle bags.
• Green SM Bike: an electric scooter with a driver. Fast and cheap for one person, but I don't recommend it to visitors over 50 in city traffic.

Why I use Green SM instead of Grab

This is my own experience, from years of booking rides for myself and for travellers:

• The cars are new. The whole fleet is recent electric VinFast models. They're clean, quiet and the air-con works.
• The drivers are employees, in uniform, trained by the company. You get the same standard each time.
• The driver usually calls before arriving to confirm where you're standing. For a visitor that's reassuring, and it saves a lot of waving at the wrong car.
• The price is fixed in the app before you confirm. No meter, no detours.

What happened with Grab in 2026?

Grab is still in Vietnam and still works. But in September 2026, many Grab drivers in Hanoi and Saigon called for a two-day "app-off" on 12 and 13 September. They were protesting falling income: Grab takes a 20% commission on motorbike rides and 25% on car rides, and drivers said that after fees and taxes they were keeping far less of each fare than before. Grab said it was "seriously assessing the situation". The dispute got wide coverage in the Vietnamese press, and a lot of local riders, me included, chose to ride with Green SM instead.

None of that makes Grab unsafe for you as a visitor. It's simply why you'll see more green cars than green-and-white ones on the street now.

How to set up the Green SM app

1. Download "Green SM" from the App Store or Google Play before you fly. Older phones may still show it as Xanh SM. Check that the developer is GSM (Green and Smart Mobility).
2. Register with your phone number. A Vietnamese number works best, because some foreign numbers have trouble receiving the code. Buy a local SIM or eSIM on arrival. See Vietnam eSIM or SIM card.
3. Switch the app to English in the settings if it opens in Vietnamese.
4. Add a payment method, or choose cash. More on that below.
5. Save your hotel as a favourite place so you can book the ride home in two taps.

How to pay for Green SM safely

You can pay by Visa or Mastercard in the app, or in cash to the driver. Foreign card support is newer on Green SM than on Grab, and some cards are declined, so:

• Try linking your card on the first day, with a short ride, while you still have cash as backup.
• Use a card with no foreign transaction fee and turn on transaction alerts.
• Only add your card inside the official app. Never give card details to anyone by phone or chat, even someone who says they're from Green SM.
• Carry small notes for cash rides. Drivers don't always have change for a 500,000 dong note. Read money in Vietnam for more on cash.

How to get a Green SM from the airport

Green SM has pickup points at Noi Bai (Hanoi), Tan Son Nhat (Saigon), Da Nang, Phu Bai (Hue), Cam Ranh (Nha Trang) and Phu Quoc. At the bigger airports there's a Green SM help desk in the arrivals hall.

1. Connect to the airport Wi-Fi or turn on your SIM after you've collected your bags.
2. Book in the app with the airport as your pickup. The app shows the pickup lane or column for your terminal.
3. Walk to that point. Ignore anyone in the hall offering you a taxi.
4. Answer the driver's call and tell them your exit or column number. If you don't speak Vietnamese, the in-app chat translates for you.
5. Check the plate number against the app before you get in.

If you fly Vietjet, you can also pre-book a Green SM airport ride when you buy your ticket and show the voucher code to the driver. For the scams to avoid on arrival in Hanoi, read Noi Bai Airport taxi scams.

Tips for older travellers

• Book a car, not a bike, unless you're very confident on the back of a scooter.
• Choose the 7-seater when you have paddle bags and suitcases. It's not much more expensive.
• Get in on the kerb side, and watch for motorbikes when you open the door.
• Ask the hotel to book for you if your phone isn't set up yet. Every reception desk knows how.
• Tipping isn't expected. Rounding up for help with heavy bags is a kind gesture.

The bottom line

Green SM (Green SM) is the easiest way to get around Vietnam's cities in 2026: new electric cars, uniformed drivers, a fixed price in the app and, usually, a call before pickup. Set it up before you fly, test your card on a short ride, and keep some cash as backup. Grab still works if you prefer it, but the green cars are the ones I'd put you in.
