Programming in progress.
SIM Card
Your phone comes with a built-in level of security protection through the use of
the SIM card. The SIM card stores all your Phonebook information and your
Nextel account identification information. Since this information is stored on
the SIM card, not in your phone itself, you can remove the information by
removing the SIM card.
NOTE: Except for making emergency calls, your phone will not
function without the SIM card.
The SIM card is located in the SIM card holder on the back of the phone,
underneath the battery. You can verify the SIM card is in place by removing the
battery and viewing the SIM card through the SIM card cover.
See “Inserting/Removing the SIM Card” on page 19 for information on locating
the SIM card. If there is no SIM card in your phone, notify your Nextel
Authorized Representative.
SIM Card Personal Identification Number (PIN)
To prevent unauthorized use of your account, you can protect your SIM card by
enabling the SIM PIN security feature. With the SIM PIN enabled, you must
enter your PIN each time the phone is powered on. You can change or disable
your PIN if desired.
NOTE: It is recommended that you enable the SIM PIN security feature
to prevent fraudulent use of the SIM card, your i 60 c phone, and
your account.
Enabling/Disabling the PIN Security Feature
Once the PIN security feature is enabled, you are prompted to enter your PIN
each time you turn on your phone. Until a valid PIN is entered, you can use the
phone only to make emergency calls.
