How to Protect Your Mobile Number
Keep Your Number Private
Don’t share your mobile number on social media, public forums, or untrusted websites. Use separate numbers for business and personal use.
Use App-Based 2FA
Prefer authenticator apps over SMS for two-factor authentication. SMS can be intercepted, but app-based codes are much safer.
Enable SIM Lock
Contact your carrier to add a SIM lock or port freeze to prevent unauthorized SIM swaps and number porting.
Review Privacy Settings
Regularly check privacy settings on all apps and services. Limit who can see your phone number and contact information.
Avoid Phishing Attempts
Never click suspicious links or provide your number to unverified callers. Legitimate companies won’t ask for sensitive info via SMS.
Regular Security Checkups
Monthly review of your accounts, check for unauthorized access, and update security settings. Stay proactive about your digital security.
Warning: SIM swapping attacks are increasing. Criminals use your mobile number to bypass security measures. Always use additional security layers beyond SMS verification.
