I got a t-mobile s4 from USA which was paid in full and never activated on any network in USA. I am now trying to use an Airtel Sim Card in India and it shows that its SIM Unlocked. On contacting the T-Mobile support they are saying that they cant provide an unlock code because the device was never activated on their network.
I am stuck because all websites providing unlock codes work on the same precondition that the device was earlier activated in a T-Mobile network. I am also not able to get into service mode and apply the sim unlocking fix as suggested in few posts.
Please provide help and suggest me the options. I am not afraid to shell some more bucks to make it work but i need assurity that the method would work.
Is there a way that i can try which doesnt require t-mobile network at all???
My android version is 4.4.2 and device has been rooted now.
