When you purchase a Nokia 1600 cell phone through any service provider, the phone is locked so that it cannot be used with any other carrier. To sign up for service with a new provider, you have to unlock the Nokia 1600, which requires getting an accurate unlock code.
Instructions
1. Get the IMEI number off of your phone by typing "*#06#" with the phone's keypad. The IMEI number will appear on the screen.
2. Go to the Nokia 1600 unlock calculator at the Unlock.nokiafree.org website (see Resources). The website is an all-Nokia phone site that has unlock codes for every Nokia phone, regardless of network.
3. Enter the IMEI number in the first box of the calculator, select your network from the drop-down list provided and select the proper generation of your phone next to "GEN."
4. Click the "Get Nokia DCT4 Unlock Codes" button to process the information and display codes for your phone.
5. Try no more than two or three of the codes that are listed for your cell phone. Entering an incorrect unlock code into a Nokia 1600 five times will lock your phone so that it cannot be unlocked by a code.
6. Use a paid service to get a verified unlock code for your Nokia 1600 cell phone. Unlock.Nokiafree.org has its own paid service at Ucables.com (see Resources).There are other paid sites available, like mrunlock.com (see Resources.) Prices vary from site to site, but most code-generating sites guarantee accuracy of their codes.
7. Remove the SIM card from your phone and power it on. Enter the unlock code, which will both begin and end with a pound sign. A pop-up message that says "Phone restrictions off" will appear to let you know that the phone is unlocked.
