About the Charging Function When you connect external power to the phone, the battery is charged. When the battery is fully charged, the charging stops. You cannot overcharge your battery.

About the Battery and the SIM Card The Battery Your phone is supplied with a Nickel Metal Hydride battery. The battery is not charged before shipment, even though there might be enough power to turn the phone on. The SIM Card Before you can start using your phone, you need to order a SIM Card from a GSM service provider. The SIM Card is a computer circuit that keeps track of your phone number, the services that you have ordered from the service provider, and your phone book information. The SIM Card sometimes contains information that lets the phone automatically change the display texts into the language of the SIM Card. Your SIM Card is supplied with a security code or PIN (Personal Identity Number) that you need to enter into the phone to gain access to the phone and network.
