Less battery duration: Possible reasons are using and charging the battery in high temperature conditions or
searching for a network constantly in a weak network area. If you are in an area with a weak signal, please
temporarily switch OFF the radio.
Unable to connect to a network: Possible reasons are that the SIM card is not effective, poor signal or being
out of the network service area. Please try either replacing the SIM card or move to a position that is more open,
i.e. if you are in a building, move nearer the window.
