China Mobile (CHL.NYSE, 0941.HKG), the world’s largest mobile carrier by users, plans to launch fourth-generation (4G) wireless service in Hong Kong this month in a bid to compete with rivals including Telstra (TLS. ASX) and PCCW (0008.HKG), Bloomberg reported. The operator will offer more than one 4G phone on its April 25th debut and ten 4G handsets this year, said Sean Lee, CEO of China Mobile Hong Kong. China Mobile’s 4G service will be priced near its 3G service, said Lee, adding that 4G users will not pay any roaming charges in mainland China. The mainland giant will become the second carrier to offer 4G in Hong Kong after Telstra’s CSL. China Mobile accounts for over 20% of the wireless market in Hong Kong, said Tiger LIn, chairman of the Hong Kong unit.
