TL;DR: SIM swap fraud in India is when a scammer fraudulently gets a duplicate SIM card issued in a victim's number by impersonating them with the telecom operator, allowing the fraudster to intercept OTPs and take over bank and UPI accounts. If your phone loses signal unexpectedly for more than a few hours, contact your telecom operator immediately to check for an unauthorized SIM swap, and set a strong PIN with your operator for any SIM-related requests. Monitor your bank accounts closely if this happens.

How SIM Swap Fraud in India Works
Scammers first gather personal details through phishing, data leaks, or social engineering, then either trick the victim into calling a fake customer care number and pressing a code that reroutes calls, or directly contact the telecom operator's outlet with forged documents to request a duplicate SIM. Once the swap goes through, the victim's original SIM stops working and the fraudster starts receiving all OTPs and bank alerts.
Warning Signs to Watch For
Your phone suddenly shows "No Service" or loses network for an extended period without explanation, you stop receiving calls or SMS unexpectedly, and you get an SMS about a SIM swap or duplicate SIM request you didn't initiate.
