SIM Card

SIM Card

Your phone comes with a built-in level of security protection through the use of the SIM (Subscriber Identity Module) 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.

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 22 for information on locating the SIM card. If there is no SIM card in your phone, notify your Nextel Authorized Representative.

NOTE:Except for making emergency calls, your phone will not function without the SIM card.

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.

Enabling/Disabling the PIN Security Feature

When 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.

After the PIN is accepted, the phone registers on the network and the idle screen displays.

When the PIN security feature is disabled, the phone can be used without entering a PIN.
