hello there....well its quite simple...it is a network restriction code .....to unlock the phone to any network you need to call the customer care of your original network provider (orange) ....just keep the model number of your IMEI handy ...this is a paid service and charges differ from network to network...it can be done locally in a mobile shop at less price...but its advisable to take help from Orange
that should solve the problem.....you will be able to use any sim in your phone of any service around the world
hope this helps

The PUK is associated to SIM card, and not to the phone. Just put a new Orange SIM card on the D900.

If the D900 is locked to Orange and your friend want to use a different SIM on it, that that can instead be done at any local phone shop for a small fee.

it is best to take the phone to a mobile service center and have them unlock it for a small fee or you can try online at unlockitnow.com or mobile2mobile.net most times thiis process take about 12-24hrss to complete.

IMEI has reported to barred,so contact Service provider to unlock the Code.

source the net for an Orange flash file to laod to your phone.

You should have a PUK number, on the plastic card where your sim card was.
Only your network service provider can give you that, if you lost the original.
