locked, you must enter the correct PIN
code to unlock it, even if you move it to a
different phone. You can still make
emergency calls when your phone is
locked, however.
IMPORTANT
If your SIM card is locked
and you enter the wrong PIN more than
three times, you must call your wireless
service provider for your unique PIN unlock
key (PUK) to unlock your SIM card.

When you check the boxes to
disable the touchscreen during a call, the
touchscreen is automatically enabled again
after you end the call.
TIP
When Phone Lock is turned on, other
people can still see the info on your
smartphone, but they cannot make or receive
phone calls or use the other wireless features
without your password.
