How to pay cash for a ride in the Grab app in Nha Trang, and what to do if Grab won't find a driver or blocks your account?

When you book through an app, check that the driver and car match. In late September 2026 a traveler said that several times different people walked up and showed him that it was his booking, although someone else ended up driving. Earlier his group had gone with a street tout who cut the price almost to the app level and showed photos of a car, but led them to a different vehicle. Five minutes in, the driver stopped, said he was tired and that another man would take them the rest of the way — the travelers sensed something was off, took their bags and walked away.

One option that accepts cash is the Maxim taxi app. In August 2026 a traveler took a Maxim car there and back, booking it simply in the app. In October another traveler wrote that he called taxis through Maxim and paid in cash.

In August 2026 a user had his Grab account blocked for "suspicious activity", even though he rode every day and had never cancelled an order. The reason for the block was never figured out in the discussion.

In late July 2026 a traveler wrote that they could not find a cash payment method in the Grab app settings. In the end they decided to simply call a taxi and pay the driver in cash at the end of the ride.

In July 2026 a traveler complained that she waited a very long time for a Grab car and struggled to cancel the order. She then booked a ride through InDrive and was on her way.
