Talking Sim unlock (remove sim lock) the SC-03D
In order to sim unlock the SC-03D it is necessary to first flash a "special" radio. Flashing the radio is possible with a CWM based recovery. Get the latest version of CWM-recovery from this forum and flash it using ODIN/Heimdall:

Then get the radio to flash from this XDA thread:

This radio is from the Galaxy Note (SC-05D) so it made my phone very very slow. However, you need this radio because it has options to make the phone sim free. Options which the original SC-03D radio does not. As soon as you flash this new radio boot the phone, run the dialer application and dial:


it might be very slow but eventually you should get to the service menu.
To access more options press [menu] then [Input key]. Then into the text box type:

Q0 (Q Zero, not QOh)

It should bring you to another menu after a second or so. Select these options:

Wait for 30 seconds , press MENU then BACK.

Wait 60 seconds. Reboot.
Congrats you're sim free. You should remain sim free no matter what radio/firmware/rom you flash.

And HomuHomu for the recovery.

No guarantee for stability but you can try this method by homuhomu:

Install this CM12 rom with TWRP:

Install google apps with TWRP:

Fingers crossed that it will work
