We would like to issue a general advisory to caution Indian telecom customers who are being arbitrarily targeted by calls fraudulently claiming the recipient customer as being a Prize/Lottery Winner.
In these types of phone frauds, the customer returns a missed call to a +92 or +375 country code and inadvertently reaches a fraudster pretending to be representative of airtel or another Indian mobile operator and informs the customer of having won some lottery/prize money. The fraudster then attempts to trick the customer into divulging sensitive personal information and to pay a commission to receive the winnings. Such commission is usually asked to be paid via an international DTH operator’s recharge vouchers.
To protect all our mobile subscribers from such malicious activities which may result in substantial increase in your phone bill, airtel would like to advise the following:

» Do not respond to any unexpected calls from a number with the +92 or +375 country code.
» Do not respond to any suspicious missed calls from unknown numbers. In case of such suspicious calls, please report the same to us immediately to your Mobile operator
» Do not get lured into any financial transactions or divulge any personal information like IMEI, Bank Account number and other information to callers offering prize money or lottery winnings. Also do not respond to any instructions to dial an international number to get the prize money.
