Sir,
I have some queries in my mind. Kindly answer me the queries mentioned below
Can I know what is the order number of the Ministry of Communication for linking the Aadhar card with my mobile SIM card.
When I purchased the SIM card, at that time I have submitted my Aadhaar card as a document proof. So, why I am again linking the Aadhaar card with my mobile SIM card.
My Aadhaar card registration at ASSAM, But I am residing at ARUNACHAL PRADESH. As per telephonic conversation with telecom company customer care service, they told me that you are unable to link your Aadhaar card number with your mobile SIM card. Now, what is the reason for this
However, the Aadhaar card number is authorized to recognize a person in all over India, Then why we cannot link Aadhaar card number getting from one State to another States mobile SIM card.
As per Telephonic conversation with Telecom company customer care service, they told me that you can link your friends Aadhaar card number with your SIM card.
Is it possible to link any peoples Aadhaar card number with my SIM card, if possible then how
