An MTN customer recently made contact with MyBroadband after he received a bill of R12 714 which is much higher than their average R200 a month on their data-only contract.
Apart from the huge bill, this customer discovered that multiple international calls had been made on their SIM despite being on a data-only contract.
Jan Vermeulen of MyBroadband says this scam is called the 'International Revenue Share Fraud'.
What these guys do is hijack your SIM and they make phone calls to a premium rated number overseas and they take a share of the profits that these premium numbers generate off of phone calls.— Jan Vermeulen, MyBroadband
Why have the services providers not stopped this from happening?
Vermeulen says the providers say they don't want to limit customers freedoms to do as they please, so premium rated numbers aren't prohibited from being dialed by default.
But customers should be able to opt in or out for such an option, says Vermeulen.
With the prevalence of fraud happening especially on mobile networks, cellphone network providers need to protect their customers against fraud like the banks do.— Jan Vermeulen, MyBroadband
Vermeulen says because the numbers are not being disclosed as fraud numbers it it difficult to say how prevalent the fraud is.
The only way to safeguard yourself right now is to monitor your bill, says Vermeulen.
