The Philippines is planning free Wi-Fi services to half of its towns and cities this year and nationwide coverage by end-2016, limiting the data revenue prospects for Philippine Long Distance Telephone Co. and Globe Telecom Inc. The free Internet service will cost the government about 1.5 billion pesos a year and will be available in areas such as public schools, hospitals, airports and parks, said Monchito Ibrahim, deputy executive director of the Information and Communications Technology Office.
