Unlocking a Nokia on 3G service requires an unlock code. The unlock code is permission to unlock your phone's software so it can be used on any network. You should try to first receive a code from your wireless carrier, because wireless carriers sometimes give customers the code at no charge. Keep in mind, however, that it is not required to give you this information, so it may not. There are other sources on the Web that you use to obtain an unlock code.
Instructions
Unlock With Wireless Carrier
1. Get your IMEI number. You can find this under the phone's battery on a white sticker. You can also find the IMEI by entering the code "*#06#" on the phone's keypad. Look at the display and the display will be showing on the screen. Write it down for future reference.
2. Call your wireless carrier and speak with a customer service representative. Give the representative your Nokia 3G's IMEI number and ask for an unlock code. Keep in mind that the representative is not required to give this information to you, and therefore, he or she may not provide it to you. If the representative will not allow you to have the code, you will have to purchase an unlock code from a third-party resource. See Resources for some ideas. When you have a code, continue to Step 3.
3. Turn your Nokia 3G's power off. Remove the battery and your SIM card from the back. Reinsert the battery only and power the phone back on.
4. Dial in the following code on the phone keypad, leaving out the quotation marks: "#pw+(unlock code)+1#". To get a "+" to show on your screen, press the "*" key two times very quickly. To get a "p" to appear on the screen, press "*" three times, very quickly. Press "*" four times quickly for a "w" to appear. After entering that code, take a look at the phone display. If the process worked correctly, the display will read "SIM Restriction Off." If you do not receive that message, try this entire step again.
