Telecom impersonation
TRAI SIM Block Call Scam
A call or message says your mobile number will be blocked in two hours because it was used for illegal activity. The caller then transfers you to fake “police” or “CBI”, which often turns into a digital arrest scam.
if you got this
Treat it as a scam until you check. Don’t click, pay or share a code. Hang up. TRAI does not call or message to disconnect numbers.
