My Samsung SGH-D600 comes up with phone lock when i start and i dont know the code

Hi whether you want to unlock your Samsung SGH-D600 mobile from network lock ..Then have a look at sites like Classicunlocking.com here they render unlock code for all mobile models at reliable cost ..You first check that whether they are rendering code for your country and network provider ..If yes then pay for it and unlock your phone ...

Sim lock is otherwise known as network lock. To remove the network lock you have to unlock your Samsung SGH-D600. Use unlock code to unlock your mobile. Get the code from the site Onlinegsmunlock.com ,and unlock it using step by step unlocking instructions.

if you ave the manual that came with the phone there should be a defualt code to put in to over-ride it usealy 12345 or 00000 depends on the phone it will be under security code or password in the manual if that dont help then ring samsung for the defualt code or go to the web site ok
