calling
Please check if the sound volume is tuned improperly
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 line
congestion.

reception to save battery.
