1.2 About the SIM Card and Battery
Always turn off your device before installing/replacing the battery and
SIM card. Follow the instructions in the Quick Start Guide to install
a 3G SIM (Subscriber Identity Module) card provided by Cingular

The SIM card contains your phone number, service details, and
phonebook/message memory. Legacy SIM cards will not function with
your device. You should consult with your Cingular representative for a
replacement SIM card. There may be fees for this service.
Your device contains a rechargeable Li-ion polymer battery. This
device is designed to use only manufacturer-specified original batteries

including your wireless service provider’s network configuration, signal
strength, the temperature of the environment in which you operate your
device, the features and/or settings you select and use, items attached
to connecting ports, and your voice, data, and other program usage
patterns.
