The SIM Card
The SIM Card
Your i55sr phone comes with a built-in level of security protection through the
use of the SIM (Subscriber Identity Module) card, which you should have
already inserted into your new i55sr phone. The SIM card stores all your
Phonebook information and your Boost Mobile 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 “Inserting/Removing the SIM Card” on page 14 for information on locating
the SIM card.
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, your i55sr 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.
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.
IMPORTANT: It is recommended that you enable the PIN security feature to protect
personal data on your SIM card. This prevents anyone from using your
phone and accessing your personal data.
