The app, which is also available for iOS and Android, is run by Indonesian telco Emtek. Why is Uber keen on BBM? Because it has 60 million users in Indonesia alone, making it a leading chat app in a country of 260 million people. The country is also witnessing a surge in ride-hailing business, and will account for 40 percent of the industry in the entire South East Asia region, with $5.1 billion on the cards this year (according to a report from Google and Temasek). Uber, which lags behind local rivals Grab and Go-Jek, clearly sees BBM as an untapped customer base.

To cater to low-end devices and overcome spotty connections, the BBM team-up relies on Uber's web-based m.Uber app (as noted by TechCrunch).
