Phnom Penh – Cambodia’s telecommunications minister, So Khun has called for more foreign firms to invest in the country’s mobile phone sector to satisfy demand that has been growing 40 percent a year in terms of the number of users, reports Reuters. “We want more foreign firms because we want a better service, cheaper, and higher quality,” Khun told reporters at a seminar on mobile phone technology, adding that the government also wanted to extend reliable coverage to the whole of the country. Cambodia has an estimated 4 million mobile phone subscribers out of a population of about 14 million people, 80 percent of whom live in the countryside. Khun said mobile phones had helped integrate people living in remote areas, particularly those in parts of the country still covered with land mines from the country’s civil war, which only formally ended a decade ago. Cambodia currently has eight mobile phone firms, all foreign-owned except market leader Mobitel, which works in partnership with Luxembourg-registered Millicom International Cellular.
