Bhai under the Samsung offer or the people who bought Lyf phone, ekyc was not there at that time. You had physically submit the aadhaar copy. I had bought many sims using aadhaar photocopy but did not give my fingerprint then.
It's not just aadhaar verification but biometric verification. Also I have come across incidence where someone else took connection using your aadhaar without your knowledge.
