HI, You have to type in security code of your phone in order to log into the phone.... By default the security code is 12345 and if you have changed it, you must be knowing.... BUT IF YOU WERE NOT ABLE TO GET INTO THE MOBILE WITH THE 12345 OR IF YOU FORGET THE SECURITYCODE, the one and the only way is to flash the mobile phone(ie, reinstalling the firmware), this cant be done by the normal person, u have to take the phone to nearest service center and flash it, they may charge u very minimal amount......
CAUTION: You may loose all the content stored in the phone memory, be careful,but no other way than doing this

How i break the security code of nokia 3110c mobile lock

To break the code you need to calculate the master security code for it and that is tough work to do. You need to have the perfect algorithm and have knowledge in programming with a perfect skill. So much talking, here is the way. It is an online security code calculator. Click here
Just supply your 11 digit phone IMEI number and use the calculated code as the moment your phone is asking the security code.

I have the 1661-2b. Its asking for a security code? Help!

Before you can get to the settings to change the security code settings you're asking how to get passed the screen asking for the code right. Usually the security code is 1, 2, 3, 4, 5 and when the keys lock, that security code is usually the last 4 digits of your phone number.

I forget security code of my nokia mobile so plz help me. when i change the sim it ask phone security code which i forget

Go to your carrier's website and search for "PUK" which means Personal Unlock Key. When you find this number (it may be the same for all phones on their network or unique to your phone model, so you may need to enter your information on the site), answer the security code wrong until it locks you out. It will then no longer ask for the security code, but the PUK. Enter the PUK and it will have you re-establish your security code. Nokia's standard security code is 12345, but i doubt you left yours the default, right?

Hope this helps,
