Which taxi apps work on Cat Ba Island?

Only the Hanh SM taxi app works on Cat Ba Island. At least, we were unable to order a taxi on Cat Ba through any other app, including Grab. Therefore, before traveling to the island, we advise installing Hanh SM right away. This is an eco-friendly taxi service using locally produced Vinfast electric cars, with the cost of a trip starting from 30,000 dong for the shortest ride, and approximately from 200,000 for traveling from one part of the island to another.
