In 2008 Pakistan was the world's third-fastest growing telecommunications market. Pakistan's telecom infrastructure is improving dramatically with foreign and domestic investments into fixed-line and mobile networks; fiber systems are being constructed throughout the country to aid in network growth. The major growth in mobile telephony was triggered by two steps taken by Prof. Atta-ur-Rahman FRS when he was Federal Minister of Science & technology. These were to introduce a "Calling Party Pays" (CPP) regime under which no charges are paid by the call receiving party on mobile phone calls. The second was the launching of UFone as a government owned mobile phone company that competitive call rates that led to strong market competition. The impact of these two measures has been the expansion of mobile telephony from 0.3 million mobile phones in 2001, to 160 million mobile phones by 2018.
