HONG KONG, April 27 (Reuters) - Chinese state-owned telecommunications network operator China Telecom Corp Ltd on Thursday said net profit rose 4.5 percent in the first quarter due to growth in users of its fourth-generation network (4G) and mobile service revenue.
Profit reached 5.3 billion yuan ($768.54 million) in January-March, compared with 5.12 billion yuan a year earlier. Operating revenue rose 5.8 percent to 91.4 billion yuan.
The firm is China’s largest fixed-line service provider and the smallest among the three state-owned telcos in the mobile business.
China Telecom said its mobile subscribers grew to 222 million in the quarter, including 138 million customers for its 4G mobile network.
China’s state-owned telcos are bracing for revenue pressure this year after the government asked them to lower tariffs. ($1 = 6.8962 Chinese yuan renminbi) (Reporting by Sijia Jiang; Editing by Christian Schmollinger and Christopher Cushing)
