SIM swap is a process where an old number is assigned to a new SIM card if its SIM card is damaged or stolen. It is sometimes called SIM/Line retrieval in many parts of Nigeria.
Fraudsters have taken advantage of the swap technology to carry out illegal activities which are popularly called SIM swap Fraud. In this article, we shall be going through everything you need to know about MTN SIM swap fraud and what you need to do if it occurs.
SIM swap fraud or SIM card hijack involves the use of social engineering techniques to take control of your SIM card.
Once the fraudster swaps the SIM, identity theft becomes relatively easy because the number is usually connected to bank, email, and social media accounts.
Fraudsters with this SIM could then log into these accounts to initiate and intercept confirmation codes texted to your device.
Once inside, the fraudster can access and drain the subscriber’s bank accounts, purchase airtime, take loans, and access email contacts to scam friends and family.
The subscriber will notice that they have lost service on the mobile phone and eventually discover they cannot login to their bank accounts or social media accounts.
