emergency calls when your phone is

unique PIN unlock key (PUK) to unlock your
SIM card.

after you end the call.
TIP When Phone Lock is turned on, other
people can still see the info on your Centro,
but they cannot make or receive phone calls
or use the other wireless features without
your password.
