How To Protect Yourself Against SIM Swap Fraud
SIM swap fraud happens when criminals try to move your mobile number to another SIM so they can intercept calls, SMS messages and account verification codes.
Because your phone number is linked to banking, email and social accounts, protecting it is essential.
Warning Signs of SIM Swap Fraud
A sudden loss of signal, unexpected SIM messages, banking alerts or login notifications can be signs that something is wrong.
No service suddenly
If your phone loses signal while others nearby have coverage, contact your network quickly.
Unexpected alerts
Treat unknown OTPs or account login notices as urgent warning signs.
How To Lower Your Risk
Keep your personal information private and avoid sharing ID numbers, OTPs or banking details over phone calls or messages.
- Never share OTPs with anyone
- Use app-based authentication where possible
- Set strong passwords on email and banking accounts
- Ask your network about extra SIM swap protection
- Act quickly if your phone loses service unexpectedly
What To Do If You Suspect Fraud
Contact your network and bank immediately from another phone. Ask to block suspicious activity, secure your accounts and investigate the SIM swap.
TLDR
- SIM swap fraud targets your mobile number and OTPs.
- Never share OTPs, passwords or personal details with callers.
- Contact your network and bank immediately if service suddenly disappears.
