How Yulong carves out a niche in competitive handset market

In China's mobile phone industry where domestic and foreign firms share the market, Yulong Computer Telecommunications Scientific Co and its founder Guo Deying seem a little out of kilter.

The company is a domestic firm, but its handsets are sold at about same price as the world's top mobile phone providers. Although not renowned for its sharp design or powerful functionality, the company's smartphone brand, Coolpad, is extremely popular with millions of Chinese users.

Over the past 17 years, Guo has successfully fought off competition from rivals by focusing on dual SIM card cell phones, which allow the use of two services from different carriers without the need to carry two phones at the same time.
