Security Features of the i 55sr Phone

The i55sr phone comes with two levels of security protection:

SIM Card

Keypad Lock

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 that the SIM card is in place by removing the battery and viewing the SIM card through the SIM card cover.

See “Removing/Inserting the SIM Card” on page 15 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 phone, your SIM card is protected by a PIN. Each time the phone is powered on, you must enter your PIN. You can change or disable your PIN if desired.

NOTE: Disabling your PIN enables anyone to use your phone. If you disable your PIN, you must still keep the SIM card in the phone to make calls.

Entering the PIN

By default, your phone is set to require you to enter a PIN.

NOTE: Your default SIM card PIN is: 0000. P It is recommended that you

change your PIN to prevent fraudulent use of the SIM card (see “Changing the PIN” on page 11).
