Zimbabwean mobile operator Econet Wireless has revealed that it has disconnected around one million unregistered lines. Legislation in Zimbabwe requires that all SIM card owners register their details to avoid mobile phones being used for illegal activities. Econet said text messages had been sent to the unregistered numbers giving users until 13 November to submit their information. While Econet itself claimed 9.2 million users at the end of February this year, figures produced by telecoms regulator POTRAZ put its active registered subscriber total at 6.62 million at the end of March. The firm is still well ahead of its two mobile market rivals, however, with NetOne and Telecel having around 3.2 million and two million customers respectively.
