Mobile Safety Tips

  • Set a Strong Password: Use a combination of letters, numbers, and special characters to create a robust password.
  • Enable Biometrics: Utilize fingerprint scanning or facial recognition if your device supports it for added security.

2. Keep Your Software Updated

  • Update Regularly: Ensure your operating system and all apps are up to date to protect against vulnerabilities.

  • Anti-Theft Features: Use apps that offer features like remote wiping and location tracking.

4. Be Cautious with Apps

  • Download from Trusted Sources: Only download apps from official stores like Google Play or Apple App Store.
  • Review Permissions: Check the permissions an app requests and only allow those that are necessary.

5. Secure Your Network Connections

  • Use VPN: A Virtual Private Network (VPN) can protect your data on public Wi-Fi networks.
  • Avoid Public Wi-Fi: When possible, use a secure connection rather than public Wi-Fi, especially for sensitive activities.

SIM Card Security Tips

2. Be Aware of SIM Swapping

  • Understand SIM Swapping: Fraudsters can transfer your phone number to a new SIM card to access your accounts.

3. Monitor Your Phone for Unusual Activity

  • Unexpected Messages: Be alert to any text messages or emails about SIM card changes.
  • Lost Service: If you suddenly lose mobile service, contact your carrier immediately as it could be a sign of SIM swapping.
