Poor 
quality of 
calling 

Please check if the sound volume is tuned 
properly  
In an area with poor network conditions, 
example: basement, the signal might be weak. 
Try searching 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 
not be able to call because of line congestion. 

Standby 
duration 
shortened 

The standby duration is relative to the network 
systems. While the mobile phone is in an area 
with poor signal strength and cannot 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.
