What is SIM Swapping?

This is when your SIM card and mobile identity is taken over by fraudsters with the purpose of manipulating your data for their gain. Normally, these fraudsters contact your network service provider to switch your phone number over to a SIM card they own. They do this so that they can easily complete the text-based two-factor authentication checks that protect your most sensitive accounts.

How to Know That Your Sim Has Been Swapped

  • The most common indicator of a SIM Swap is if your SIM card is no longer active. When you completely lose service and can not send or receive calls or text messages.
  • You may also receive a notification or text message saying that the SIM card for your number has been changed and that you should call customer care if you didn’t make the change.

How to Guard against Sim Swapping

  • Use a PIN on your SIM card: Most mobile network service providers have an option for you to secure your SIM card with a PIN. Placing a layer of protection makes it hard for an attacker to compromise your SIM card.
  • Opt for other Two-factor authentication methods: One danger of SIM swapping is that the attacker can now have access to all your accounts which enabled two-factor authentication by SMS. Opt for more secure methods like Google Authenticator.
  • Guard your private details jealously: Posting personal information like your telephone number online just simplifies the work of attackers by offering some information needed to carry out a SIM swap. In countries like Uganda, you need a National Identification Number (NIN) in order to register your SIM card. In case you carelessly post your NIN online, you are just making work for attackers easy.
  • Be deliberate about your online behavior: Attackers use phishing emails and other ways to try and access your personal data. Be careful what information you give out online and what links you click.
