How to raformat my nokia 3100

are you asking for security code for your nokia 3100? if you forgot your security code then try default code "0000" or "1234" and if it does not work then go for master reset..try unlock-free to get master reset code for your mobile and reset your mobile..

Hi,
Glad to be of service. If you forgot your security code and if you did not change it from the beginning, the default security code is 12345. But if you did change it and you really don't know the security code you may contact the Nokia Care Center in your country. You may use this link for you to check the number to call to: http://www.nokiausa.com/get-support-and-software/contact-us
I hope I answered your question.
Thanks a lot!!
