What is my phone restriction code of Nokia C3-00.1?


A Nokia C3 unlocked mobile phone works on all GSM networks. The Nokia C3 needs a Nokia unlock code in order to remove the SIM lock that comes on most SIM based cell phones by default. If your Nokia C3 has a SIM lock on it, then it will prevent you from using the mobile phone with any other carriers.I would first recommend you try getting a Nokia C3 unlock code by calling up your current phone carrier. In exchange, they will need your Nokia C3?s IMEI number. Your IMEI number is unique to your mobile device and the Nokia unlock code will be calculated using it. You can get the IMEI number on your Nokia C3 simply by typing *#06# and hitting the enter or send button. If you do not currently have a carrier or cannot get a free unlock code, then I would reccomend trying some of the unlock code websites that I have reviewed below.
Once you have your unlock code, you can begin the Nokia C3 unlocking steps below.
How To Unlock A Nokia C3 (SIM Unlock)1. Power ON your Nokia mobile phone without your SIM card.
2. Now type: #PW+CODE+1# (Where CODE is your Nokia unlock code)
3. Your phone should now show "SIM Restriction Off" and is unlocked.
Note: You must press the * key several times to get the characters for 'P' and 'W'.
If you would like to learn more about the Nokia C3 cell phone, then try reviewing some of the other related reviews below. Enjoy!
Note: The free unlock instructions provided on this site only work with GSM or SIM card versions of the Nokia C3. As always there may be already unlocked versions of this mobile phone, but generally cost a lot more then unlocking it yourself.

Getting a free code from your carrier doesn't always work
So try this unlock service HERE
If it does not support ur phone - then try this WEBSITE HERE

for the pearl: you will need to contact your service provider if you need to unlock the sim to use it with another carrier....it is free but it will take a few days to get the code back if they have tot contact the manufacterer....but you need the 16 diget code......after you get that, go to options, advanced options, sim card, type MEPPD. scroll to sim card, type MEP and pres the ALT key and then the 2 key.

if that doesnt work, instead of typing MEP2, try pressing and holding the ATL key and type MEPPE

if this works, a window will pop up asking for the unlock code....

for the WING: not as hard....just contact the service provider....once you do that....put a foreign sim in the phone and turn it on.....a dialoge box will show up and ask you to imput the 16 number code.....

**NOTE** a forgein sim will need to be in both phones in order for this to work....
