The Postal and Telecommunications Regulatory Authority of Zimbabwe (POTRAZ) says that the country’s three mobile operators are all behind with payments to the Universal Service Fund (USF). A report from The Herald quotes POTRAZ acting director Baxton Sirewu as saying that cellular market leader Econet has been the biggest contributor so far, handing over USD53 million of the USD67 million total payments since the fund was set up in 2009. State-backed rivals Telecel and NetOne have paid USD10 million and USD4 million respectively. The regulator has not disclosed how much each operator still owes to the fund. At the start of this year the government raised the required level of contributions, from 0.5% of a telco’s gross annual turnover to 1.5%. Authorities expect the hike to raise USF payments to a combined USD13 million in 2016.
