How to remove Phone freeze
--------------------------

A frequent reason for Freeze Code to be enabled is when user enters several erroneous NCK codes.

If your cell phone shows a Phone Freeze message use the back up code to unfreeze it.
Enter the 8-digit code with SIM card in the phone when the Phone Freeze message is displayed, then press OK button (middle buttom, depending on phone branding can be called differently).

You will not see text appear on screen while typing.

You can now proceede to entering Network Unlock Code.

Not all samsung phones will have a back up code.
