have code encrypt protection. Each time the phone is switched on, you must enter
the PIN1 code so that you can unlock the SIM card and then send or receive calls.
Press the ON / OFF key to boot the phone; enter PIN1 code, press to clear
the error input, press to confirm
If you enter the wrong PIN1 code in several times, SIM card will be locked. In this
instance please contact your SIM card network operator.

In order to prevent unauthorized use, you can lock your phone screen. Every time

the phone.
Users can clear the unlock pattern (see "Security Settings"), in this case, the phone
cannot prevent unauthorized use.
