Do I need a hardware and a cable to connect PC to my phone? Or there's a software calculator where I will just input the imei number then it generates code?
hi
friend instead of using cable you can try codes
i helps a lot
and it consumes your time
you can try here Online GSM Unlock.com - Samsung Supported Models
they provide codes to unlock
here select the country and the network to which your phone get locked and get the unlock codes at reliable cost.
