Peru was reintegrated into the global economic system, and began to attract foreign investment. The sell-off of state-owned enterprises led to improvements in some service industries, notably local telephony, mobile telephony and Internet. For example, before privatization, a consumer or business would need to wait up to 10 years to get a local telephone line installed from the monopolistic state-run telephone company, at a cost of $607 for a residential line. A couple of years after privatization, the wait was reduced to just a few days. Peru's Physical land based telephone network had a dramatic increase in telephone penetration from 2.9% in 1993 to 5.9% in 1996 and 6.2% in 2000, and a dramatic decrease in the wait for a telephone line. Average wait went from 70 months in 1993 (before privatization) to two months in 1996 (after privatization). Privatization also generated foreign investment in export-oriented activities such as mining and energy extraction, notably the Camisea gas project and the copper and zinc extraction projects at Antamina.
