Trai — other state aadhar number link to another state mobile number.

Address:

North 24 Parganas, West Bengal, 700054

Mai abhi kolkata me rhti hu aur kolkata ka mobile number use karti hu, but mera permanent address bihar hai and mera aadhar card bihar se bana h,
Phir mai kaise apne aadhar number ko apne mobile number se link karungi?
Maine customer care ko call kiya but unhone bola ki, aadhar card aur mobile number dono ek hi state ka hona chahiye varna band ho jayega.
To mai kya karu?
