SIM card and battery
About your SIM card
When you subscribe to your network operator, you receive
a SIM (Subscriber Identity Module) card containing your
registration information, PIN code, etc.
Like a credit card, it should be kept secure and handled
carefully. Do not bend, scratch or expose it to moisture. Avoid
static electricity.
To avoid corrupting your SIM card’s memory, always switch off
your phone before removing or inserting your SIM card.
About your battery
Your phone uses a Li-Ion battery. Make sure to use an
authorized battery and charger only. For more details, please
inquire at your nearest dealer.
note:
Your phone is powered by a Lithium Ion (Li-Ion)
battery. Unlike other forms of battery technology, you can
recharge your battery while some charge remains without
reducing your phone’s autonomy due to the “battery memory
effect” inherent in those technologies.
