While the company initially profited from domestic sales, it vowed to use proceeds of its 2004 Hong Kong IPO to further expand R&D, overseas sales to developed nations, and overseas production. Making headway in the international telecom market in 2006, it took 40% of new global orders for CDMA networks topping the world CDMA equipment market by number of shipments. That same year also saw ZTE find a customer in the Canadian Telus and membership in the Wi-Fi Alliance. More customers in developed nations soon followed Telus's lead, and in 2007 ZTE sold to UK's Vodafone, Spain's Telefónica, and the Australian Telstra, in addition to garnering the greatest number of CDMA contracts globally. By 2008 ZTE had achieved a global customer base, with sales in 140 countries.
