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.

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