locked. If the handset lock is activated, you have to input handset
password and or PIN before using. If PIN code is activated, you

Poor quality of calling
Please check if the sound volume is turned low. In an area with
poor receiving condition, example: basement, the signal might
be weak. Try reaching a location with stronger signal reception
and call again. While using the mobile phone in the peak period
of communication, like commute time, you may be unable to
call because of network congestion.
Standby duration shortened
The standby duration is relative to the system setting of
network. While the mobile phone is in an area with poor signal
strength and can not receive the signal, the handset will
continuously search for a base station. This will significantly
reduce battery charge. It is recommended that you turn off your
mobile in area with no signal reception to save battery and or
turn on Flight Mode.
Continuous Internet (Data/WiFi) usage reduces battery life
significantly, also taking into consideration of other network
factors.
If battery is damaged, replace with new battery.
