Question about Samsung SGH-D900 Cellular Phone
You will want to contact the original carrier of the phone for the proper unlock code. Currently the SIM is locked to the original carrier and the code releases it to any carrier.
If you are unable to obtain the code from the original carrier there are websites where you can purchase an unlock code from.
Be careful though... if the wrong unlock code is entered too many times the phone will permanently be locked to the original carrier.
