Use your phone anywhere in the world when it is unlocked.
Most Nokia 1600 phones are locked when purchased. This means that they can only be used on one wireless network. When the phone is unlocked, it is possible to use a cell phone plan from any wireless network around the world. An unlocked phone allows you to save money by using local SIM cards and avoiding expensive roaming charges. The SIM card contains the data for the cell phone and can easily be changed when the phone is unlocked. In order to unlock your Nokia 1600, you need an unlock code from your current cell phone provider.

3. Type in the following line, "PW+unlockcode+1#". The unlock code is the eight digit unlock code you received from your cell phone provider. Press enter when the line is typed.
