Friends,So today at around 10:21 PM I received a missed call from +918017-xxxxxxWhen I called back the number, either it was said that the number is unreachable or the call wouldn't connect.Now, even though media reports state that such SIM cloning calls originate from +92; #90 and #09 numbers, I am still apprehensive about falling into such a trap myself.So does anybody have any idea whether any such cloning calls have been reported to be originating from +91 numbersSo far, the balance on the mobile is still intact and I've also notified the vodafone CC and Nodal desk about it via email and have requested them to run the necessary diagnostic tests to confirm that there is no unusual activity observed on my mobile number.I used the several online missed call trackers available and found that the number is from Kolkata circle itself. In fact the number on which I received the missed call also starts with 8017Do I need to be concerned here or am I just being paranoid?Kindly adviseThanks!
