Disclosure: VietSIM sells prepaid eSIMs for Vietnam, and an app ride needs data. We are not paid by Grab, Be or Green SM, and the figures here come from their own pages.
The price, and what sits outside it
The useful thing about the app is that the number is agreed before the ride, not argued after it. Grab puts it plainly: fixed and transparent fares, shown before you book, and the final displayed fee is what you pay.
Four things move that number, all listed by Grab itself:
- Demand and supply. Rain at five o’clock is the classic case.
- Tolls. Not included in the quoted fare.
- The hours between 22:00 and 05:59. A surcharge applies.
- Changes you make. Extra stops, a new route, or cancelling late.
None of that is hidden, and none of it is a scam. It is a pricing table, and travellers who have read it stop feeling ambushed by the late-night number.
GrabBike, and when it beats the car
A motorbike costs less and moves through congestion that a car sits in. For one traveller crossing Hanoi or Saigon with a day bag, it is the cheerful option and often the quicker one.
It stops making sense the moment you have a suitcase, a child, or weather. Grab also offers trip sharing with someone you choose, which is worth using on a first bike ride while you work out how the traffic behaves.
Paying
Cash works. A card in the app works and saves you needing small notes on day one. The app names the payment method on the booking screen, so glance at it before you confirm.
Be and Green SM
Grab is not the only app on Vietnamese phones. Be is a domestic super app with beBike, beCar and beTaxi running in more than 20 cities. Green SM runs an entirely electric fleet, cars and motorbikes, bookable through its app, its website or a hotline.
Two apps on a phone is a practical habit rather than an indulgence: when one shows nothing available in a quiet district at a busy hour, the other often does.
The part that has to be ready first
Every one of these apps is useless without a connection. The booking, the map, the driver’s call and the receipt all travel over mobile data, and airport wifi is a poor substitute while standing at a kerb with bags.
Work out what you need in how much mobile data for Vietnam, pick a plan in the Vietnam eSIM store, and read the arrival routes in Hanoi airport to the Old Quarter and Tan Son Nhat to District 1.
