The local mobile telecom companies, Orange and MTN in Cameroon have been fined over $160 m for failing to pay taxes on games and gambling services.
A probe into the sector led to fines totalling $283 million and found other companies including Camtel and Viettel in violation of reguations.
The Telecommunications Regulatory Agency says MTN and Orange are also accused of tax evasion on their money transfer system, known as Mobile Money.
The report is another blow for MTN, which is already contesting a $3.9 billion fine in Nigeria for failing to disconnect users with unregistered SIM cards.
Unregistered SIM cards can be used for criminal activity – a growing concern in Nigeria
MTN successfully lobbied to have the fine reduced from $5.2 billion in December.
