I went to airtel shop to buy a sim. During registration, one of the airtel staff gave the registration officer a sign pointing one finger up indicating one. Immediately the registration officer brought out extra sim and start entering the detail on his tablet he uses for registering me, when I asked him what was going on, that I needed just one sim, he said he is just checking something.

To cut the story short, I am suspecting that the guy uses my profile to register extra sim which they might use for illegal activity. How do I check if my profile is used to register extra sim? I don’t have the detail of the sim but I have the details of the sim I registered that day
