A fraudster can perform an illegitimate SIM swop with your cellphone service provider. If a fraudster has a false copy of your identity number or has all of your personal details available they can manipulate your cellphone number to receive SMSes that should be going to you, for example, an OTP.
This means that they are one step closer to logging into your account. This is why you must never share personal information like your ID number, banking details, online banking login credentials, PIN, password, OTP, or cellphone number with strangers or suspicious digital sources.
- Activate app authentication on your mobile banking app to stop fraudsters from using SIM swopping to access your account
- Protect your personal, bank account and cellphone account information when you are talking to strangers or busy online
- Immediately investigate when you notice that you are not receiving calls and messages
- Keep your phone switched on – otherwise, you will not notice when your SIM card has been swopped
