Kids playing with my phones security settings.

One of my kids have changed and set it to on, that is my security code. so now when i turn my phone on it wants a security code that i dont know and no one is owning upto setting this. it is a 4 dig number, and only numbers allowed. how can i reset this phone without using a hammer please.
the phone is a lg tu500s. telstra. i have searched for answers and all codes i have found want you to use either # and or * with numbers but only allows a four dig number. its a pre paid sim, and cant use the last four dig of that number or 0000 or 1234 and have know idea what it could be.

In my phone other sim was not start when the sim was start phone was say that enter security code.What I will do with my phone.

your phone is set to a phone security level, which means that when you change or use another simcard then it will ask for the security code. if you were not able to change the security code of your phone the default security code is 12345 you can get rid of that security code by navigating your phone to settings and phone setting there you can see the phone security setting level was set to phone security, try to change it to none.

I want to change Nokia 3110c security code from default 12345 to any other number

From your phone
menu>settings>security settings>change access codes>security code change>

then you enter the default of 12345, after that, you would be prompted to enter the new code of 5 digits. You would be asked to re - enter the new code. Then your code would be changed.
Hope that was helpful?
Please do indicate.

Hi.... i am using nokia 2690 how to lock the cell with password ???? plz guide me sir :(

Select Menu > Settings > Security and from the following options:
  • PIN code request or UPIN code request-to set the phone to ask for your PIN or UPIN code every time the phone is switched on. Some SIM cards do not allow the code request to be turned off.
  • Security level > Phone-to set the phone to ask for the security code whenever a new SIM card is inserted into the phone. If you select Memory, the phone asks for the security code when the SIM card memory is selected, and you want to change the memory in use.
  • Access codes-to change the security code (default code is 12345), PIN code, PIN2 code, or restriction password.

Kid play with my nokia 6300. The security code is needed to unlock phone. Try all the normal nokia code 12345 the phone still won't unlock. I'm noy sure what code the kid press for the security code? My...


The default Security code is 12345.

If you changed it and forgot the security code please contacts your device dealer. They will provide you the default security code so that you can use your phone.

This security lock prevents thieves from being able to make use of stolen handsets that is why it can only be unlocked by authorized device dealers.

Thank You

I have nokia 7230 mobile phone iwant to do security code wht should do

go to menu then click settings, security, change security code, type 12345 (default security code). after this step the phone will ask you to enter a new code after this, you will be asked to verify the code (need to retype your new security code then) then, your code is changed.

to activate the security code for your phone to use:

1. go to settings
2. choose security
3. choose security level
4. choose phone
5. restart your phone

after the restart, you will be asked to type first your new personalized security code before you can use your phone.
