Qiao Xing is the first Chinese telephone manufacturer listed on the NASDAQ. (Symbol: XING) Qiao Xing''s net sales have grown from USD46 million in 1997 to USD365 million in 2009. A majority owned subsidiary of Qiao Xing, or better known as CECT, is a top three domestic seller of mobile phones in China, with product lines that include Dual SIM phones and Windows Mobile PDA Phones. Would be purchasers of CECT phones in China should beware that there are multiple fake CECT brands in China. For example, the CECT P168, which is an Apple iPhone clone, is not designed or manufactured by Qiao Xing. Qiao Xing does not produce clones of Apple, Nokia, or Samsung products. Other companies in China, disguised as CECT, produce these clones. A dual SIM mobile phone is one which holds two SIM cards. Initially, dual-SIM adapters were made available to use in regular mobile phones to allow them to contain two SIMs, and to switch from one to the other as required. This combination is called a standby dual-SIM phone.
