Lenovo Group aims to secure a strategic co-operation deal soon with China Mobile, the world's largest wireless network operator, to encourage domestic adoption of its 3G smartphones and media tablets. China Mobile, which had 575 million subscribers as of last month, remains the only mainland carrier without a distribution deal for Lenovo's popular 'LePhone' handset and the new 'LePad', which is slated to launch next quarter. 'We are in discussions to get our devices to run on China Mobile's network,' Lenovo chief financial officer Wong Wai-ming said. 'Our objective is to become a large player, so it would be very difficult for us to achieve a big market share without our devices working on all three [mainland] operators' networks.' Lenovo, the world's fourth-largest supplier of personal computers, has the biggest market share among domestic smartphone brands on the mainland, following LePhone's release with China Unicom in May and China Telecom in September. Research firm Analysys International estimated that Lenovo had a 4.1 per cent market share for seventh place among the top 10 smartphone brands on the mainland in the third quarter. Global brands Nokia, Samsung Electronics, Motorola, Sony Ericsson, Apple and BlackBerry maker Research In Motion remained ahead of Lenovo in domestic smartphone sales, with a combined market share of 74.9 per cent. The Lenovo Mobile business, which still sells more 2G handsets on the mainland, posted a consolidated turnover of US$217 million in the quarter to September. Its overall unit shipments in the quarter grew 57 per cent year on year. Wong said Lenovo planned to invest more in its mobile business 'to accelerate sales growth for LePhone and LePad'. A deal with China Mobile would mean Lenovo's engineers must adapt LePhone, which runs a customised version of the Google-developed Android operating system, to the carrier's TD-SCDMA 3G network. The current LePhone models support China Telecom's CDMA2000 EV-DO 3G network and Unicom's more mature WCDMA 3G system. 'We know that eventually we will work with China Mobile's network,' Wong said. 'It's just a matter of time.' According to the Ministry of Industry and Information Technology, mainland 3G users reached 38.64 million last month. China Mobile led the sector with 16.98 million 3G subscribers. Unicom had 11.66 million 3G users, while China Telecom had 10 million.
