Know owner details of Airtel sim

I was wondering when I had a sim card and even I didn't knew who belongs to this sim.
Actually I took it from my brother in law and when he was at Mumbai. He asked someone to get a sim. I was thinking if anything happens to this sim . I can't get it again because I am not owner and that number is linked with my documents Bank and so many online sites. I could get in trouble if lose or broke.
What I did ?
I just ported that sim to another company using my documents, So recent documents updated and I became the owner.
