In Security Settings On The X497, What is the SIM Lock Function And How Is It Used?
When the SIM Lock feature is enabled, your phone only works with the current SIM. You must enter the SIM lock code to unlock the SIM so you can use a different SIM card. Once you have entered the lock code, you are asked to confirm your entry.
