Locking your phone (Phone Lock)
You can lock your SIM card to prevent
unauthorized calls and use of other
wireless features. When your SIM card is
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 AT&T Wireless
for your unique PIN unlock key (PUK) to
unlock your SIM card.

and select OK. (Unless you changed
your PIN, enter the default PIN,
provided with AT&T Wireless
account materials.)
DID YOU KNOW ? 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 Treo 680,
but they cannot make or receive phone calls
or use the other wireless features without
your password.
