WTT HK Limited (Chinese: 滙港電訊有限公司), was the second largest fixed-line telecommunication operator in Hong Kong.

[5] Established in 1995 as New T&T Limited,[6] it was one of the first[citation needed] telecommunication operators to be offered a fixed line license after the Hong Kong Government decided to open this market to competition;[7] Cable & Wireless Hong Kong Telecom had heretofore enjoyed a monopoly.

[11] By 2006, the company decided to differentiate its offerings by providing some services through a different unit; Wharf T&T would focus on business clients and subsidiary i-Cable Communications, residential ones.

[13] In 2016, MBK Partners, North Asia’s buyout firm, and TPG, a global alternative asset firm, completed the acquisition of Wharf T&T Limited from The Wharf (Holdings) Limited on 9 November 2016.

[20] Subsidiaries include COL Limited, which provides IT services to businesses having more than "40 years experience in the IT sector";[6] and WTT eBusiness Limited (WeB), which was established in January 2007 and is an Internet service provider catering to SMEs.
