LUCKNOW: Next time if you get a missed call starting with +92; #90 or #09, don’t show the courtesy of calling back. BSNL has issued alerts to subscribers — particularly about the series mentioned above — saying that calling the number back after a missed call may make a user susceptible to SIM card cloning. There is, however, confusion over this claim made by some BSNL and intelligence officials. Cloning a SIM card requires physical access to it or the interception of the communication between the caller and his or her cellphone operator’s network.
It is said that one lakh subscribers have fallen prey to this scam. Intelligence agencies too are said to have confirmed to the service providers particularly in the UP West telecom division that such a racket is going on and the menace is growing fast. “We are sure there must be some more similar combinations that the miscreants are using to clone the handsets, including SIM, and all the information stored in them,” an intelligence officer told TOI. (This claim made by this intelligence official seems implausible, or nearly impossible.)
General manager of BSNL, RV Verma, said the department had already issued alerts to all the broadband subscribers and now alerts were being SMSed to other subscribers as well.
