The world's largest telecoms tower operator sold 43.1 billion new shares, or 25 percent of enlarged share capital, at HK$1.26 ($0.1605) each, valuing the firm at about $28 billion, the people told Reuters. The top of the range was HK$1.58.
The float is widely seen as a test of Hong Kong's IPO market as investors consider several large deals at time when the benchmark Hang Seng Index down about 14 percent from its January peak.
It also comes as China's economy has begun to lose growth momentum this year amid a government push to reduce debt and an escalating trade conflict with the United States.
China Tower declined to comment on the pricing. The people declined to be identified as the information was not public.
At $6.9 billion, China Tower's IPO will become the world's biggest listing since Postal Savings Bank of China Co Ltd's $7.63 billion float in Hong Kong 2016.
China Tower operated 1.9 million tower sites and had 2.8 million tenants at June-end. It plans to use 60 percent of the IPO proceeds to build towers and update existing ones, as it accelerates fifth-generation (5G) network construction. It will use the remainder for loan repayment and general working capital.
Its chairman, Tong Jilu, told a news conference in Hong Kong last week that the state-controlled firm would continue to invest in 5G-related business that "can bring exciting new opportunities".
The float is also the latest amid a government push to inject new life into bloated state-owned enterprises by encouraging private capital investment in such enterprises.

China Tower's IPO price represents a multiple of 7.1 times adjusted earnings before interest, tax, depreciation and amortization (EBITDA) for 2018, and 6.5 times its 2019 EBITDA, as forecast by its underwriting syndicate.
The firm secured $1.4 billion from 10 cornerstone investors including Chinese investment firm Hillhouse Capital Group, U.S. fund firm Och-Ziff Capital Management Group LLC and a unit of Alibaba Group Holding Ltd, covering 20 percent of the IPO.
The company was formed in 2014 from the tower operations of China's three state-backed telecoms providers - China Mobile, China Telecom and China Unicom - to reduce duplication.
Its operating revenue in 2017 rose nearly 23 percent to 68.7 billion yuan ($10 billion), while profit rose more than 25 times to 1.9 billion yuan, the IPO prospectus showed. Its three telecoms shareholders contributed almost all its revenue last year.
China Tower's shares will start trading on Aug. 8.
