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. This means

that, 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.
