History

In 1999 and 2000, Hutchison Telecom sold its Orange and VoiceStream interests and re-invested the greater part of the proceeds to develop its global third-generation (3G) mobile broadband telecommunications business, based on the European UMTS (W-CDMA) 3G standard. In early 2007, Hutchison Telecom made headlines by selling its 67% interest in the Indian mobile phone network Hutch Essar to Vodafone for US$13.1 billion (of which $2 billion was debt). In December 2007, minority shareholder of Hutchison Telecommunications International (HTIL), Orascom Telecom, sold the 14.2% stake of HTIL, to HTIL's parent company Hutchison Whampoa, for HK$7.5 billion (approx. US$962 million). Orascom also reduced the stake from 19.3% to 16.3%, through a private placement of shares to the market in October 2007. In 2009, Hutchison sold its controlling stake in Orange Israel to Scailex Corporation. Thus it ended using the Orange brand for providing mobile services. In 2009, it spun off Hutchison Telecommunications Hong Kong Holdings (stock code: 215) to be listed on the Stock Exchange of Hong Kong. In 2010, the company was privatized. Current operations

Indosat Ooredoo Hutchison 

In July 2005, Hutchison Telecom acquired a 60% equity stake in PT Hutchison 3 Indonesia ("H3I", formerly known as PT Hutchison CP Telecommunications ("Hutchison CP Telecom" or "HCPT"), PT Cyber Access Communication and PT Telindo Inti Nusa) from the Charoen Pokphand Group Indonesia. In 2006, H3I announced that it retained Siemens to design, build and operate state-of-the-art 2G and 3G nationwide wireless networks. H3I launched its commercial services on 30 March 2007 under the 3 brand. Indonesia is an extremely attractive wireless market with a sizable population and a relatively low mobile penetration rate. It is an excellent example of Hutchison Telecom's vision and strategy in achieving growth in emerging markets. At the end of September 2009, H3I's customer base grew to approximately 7.3 million. In September 2021, it was announced that the latter company would be merged with Ooredoo's Indosat (who operates IM3 Ooredoo networks) to form Indosat Ooredoo Hutchison (IOH) and was closed the merger on 4 January 2022.

In July 2004, Hutchison Telecommunications (Vietnam) S.à r.l. ("Hutchison Telecom Vietnam"), a wholly owned subsidiary of Hutchison Telecom, entered into a business cooperation contract with Hanoi Telecom Joint Stock Company. In February 2005, Hutchison Telecom was granted an investment licence by the government for the project and in January 2007, launched CDMA service under the brand HT Mobile. While they offered a superior network, the market uptake was greatly hampered by the lack of affordable CDMA handsets, in particular, those with the Vietnamese language option, coupled with the trend of leading manufacturers to scale back handset development for this market. On 8 March 2008 they received government approval to convert from CDMA technology to GSM. After the successful conversion, it launched GSM services in April 2009 under the new brand "Vietnamobile". The brand surpassed the one million customer mark within six months of launch, mostly in the prepaid segment. Vietnamobile offers some of the highest growth potential in the region.
