MTN has warned customers to beware of a new scam doing the rounds.

In this scam, a supposed MTN call centre agent requests the customer’s security details under the pretext that they are blocking the processing of a SIM swap request that is being made on the subscriber’s number without their knowledge or authorisation.

The scammers then use the customer’s responses that they obtained during the call to perform a fraudulent SIM swap.

According to the company, MTN will not contact customers from its call centre to block the processing of a SIM swap request.

When performing a SIM swap, customers have a couple of options available to them:

* Post-paid customers are required to visit a MTN store to activate their SIM swap, and they will be required to produce an ID document.

* Pre-paid: customers are able to process a SIM swap via a USSD code, call centre or by visiting a MTN store. When opting to visit a MTN store, subscribers will be required to produce a ID document. Subscribers who choose to activate remotely will be required to complete security questions.
