What you need to know
Fraudsters collect your personal details through phishing or data leaks, then convince a telecom store to issue a replacement SIM or eSIM. Once active, your phone loses signal and all OTPs reach the criminal, who drains net banking and UPI accounts.
If your mobile shows 'No Service' for an unusually long time without reason, contact your operator immediately and alert your bank to freeze online access.
Use app-based authentication where available, set a SIM PIN, keep your bank's registered email active for alerts, and never share SIM-related details on calls claiming network upgrades.
If you have lost money, call the National Cyber Crime Helpline 1930 immediately and file a complaint at cybercrime.gov.in. Inform your bank at once: under RBI's customer-liability rules, reporting an unauthorised electronic transaction within three working days generally limits your liability to zero when the fault lies with a third party. In Mumbai, Thane and Navi Mumbai you can also visit the nearest police station or cyber police cell with your bank statement and screenshots.
