Bengaluru: Two arrested for converting international calls into local

BENGALURU: Central Crime Branch (CCB) sleuths busted an international illegal telephone racket operating in the city, and arrested two persons who were converting international calls into local ones using a SIM box and mobile app, causing loss of several crores of rupees to the government and telecom companies.

A SIM box is a device that allows the routing of phone calls through VoIP (Voice over Internet Protocol) networks, effectively bypassing traditional international routes and terminating calls as local. It houses multiple SIM cards and connects to a VoIP gateway.
