💡 Quick Tip

Your mobile number is the key to your savings. Learn how hackers duplicate your SIM card to steal bank codes and how to stop it.

Identity Theft in Your Pocket

SIM Swapping involves tricking your carrier to issue a duplicate SIM. Once they have your number, they receive bank verification SMS codes. Protection: 1. Request a security PIN for SIM duplicates. 2. Use authenticator apps instead of SMS for 2FA. 3. Be careful with public mobile info.

📊 Practical Example

Your phone suddenly says "No Service". You wait, but it doesn't come back. You call your carrier from a friend's phone and find out a duplicate was issued 20 mins ago. By blocking it immediately, you save $3,000 from being transferred.
