How to resart in starting if put new sim in my mobile it asking security code how im restart my mobile


If it is a used phone and it was never wiped. Then the old security code is active. Changing the sim does not change the security code of the device. If it is asking for a sim security code, then the sim card is locked and you must have the code or the sim is just a piece of plastic. Did the service provider put a code on the sim and forgot to tell you.?..Take the sim back and ask for another without the security code on it. Sims can be coded so that if they are stolen they cannot be used in another device.

I need to know the ulock code for a motorola w376g cell phone


Your phone’s four-digit unlock code is originally set to 1234 or to the last four digits of your phone number.
The six-digit security code is originally set to 000000.
Your service provider may reset these codes before you get your phone.
If your service provider didn’t change these codes, you should change them to prevent others from accessing your personal information. The unlock code must contain four digits. The security code must contain six digits.
To change a code or password:
Find it: Settings > Security > New Passwords
You can also change your SIM PIN codes or callbarring password.
Select the type of code you want to change, enter the old code when prompted, and then enter the new code.
If you forget your unlock code: At the Enter Unlock Code: prompt, try entering 1234 or the last four digits of your phone number. If that doesn’t work, contact your service provider.
If you forget other codes: If you forget your security code, SIM PIN code, PIN2 code, or call barring password, contact your service provider.

Resetting Security Code


SIM pin code:
This is a pin code that locks the sim card until you enter the correct code. This protects your account, even
if your sim is put into another handset. To reset it, you need the PUK code:
Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.
Which is the one that you want?
The default security code for Nokia is 12345
