Huawei Technologies Co. Ltd., China's largest mobile network equipment maker, is bursting with vitality thanks to robust device sales.

The Shenzhen-based company said its device sales jumped around 50 percent year on year to reach $6.7 billion last year, with handheld device shipments exceeding 150 million units, up 30 percent.

While it still relies on its network equipment business as a pillar source of revenues, Huawei has been making inroads into consumer devices because of buoyant global demand for smart phones and tablets.

In 2011, Huawei joined hands with China Telecom to launch a series of smart phones including the C8500 and C8650, which have become market hits.

Wan Biao, head of the firm's device unit, said around 65 percent of the handsets were purchased through wholesales by telecom operators, while the remainder was sold via online retail sales.
