Along with many other Indonesians, 26-year-old Emerra Tioanda sees her smartphone as a "life-saver"; helping her negotiate the daily traffic jams in capital Jakarta by being an entertainment player and giving her access to retail websites where she buys everything from clothes to airline tickets.

"I first started shopping online when I was studying in Singapore. After I returned to Jakarta, I continued to do so because it's convenient and the fashion is more updated compared to the malls here," Tioanda told CNBC. "It's also time-saving... since I'm stuck in the traffic almost everyday, why not get something done right?"
