Nokia 5320 has set SMS password on this machine. How to cancel the password?

Hello, the power-on password can be set in mobile phone settings/general/security settings/mobile phone and sim card/power-on pin code.

Then the SMS password and address book password you said are all set by software. Just download the mobile phone encryption software in the place where the mobile phone downloads the software, such as 3g portal or other forums. There are many kinds of software. You are dazzling, but the functions are similar, that is, you can set the password to open SMS or address book.

Finally, I wish the landlord an early solution to the problem. What else can you ask me?
