According to Reuters, Sifiso Dabengwa will be replaced by non-executive chairman Phuthuma Nhleko for a maximum of six months, Africa’s biggest mobile phone company said in a statement.
MTN was fined in October by the Nigerian telecoms regulator for failing to cut off users with unregistered SIM cards.
The company said it continued talks with the Nigerian authorities over the fine.
“Due to the most unfortunate prevailing circumstances occurring at MTN Nigeria, I, in the interest of the company and its shareholders, have tendered my resignation with immediate effect,” Dabengwa said in a statement.
