The standby time is related to
your service provider system
configuration. The same
phone used with different
service providers’ systems
will not provide exactly the
same length of standby time.
If you are located in an area where
signaling is weak, temporarily
switch off the phone.
The battery is depleted. In
high temperature
environments, battery life will
be shortened.
If you are not able to connect
to the network, the phone will
continue to send out signals
as it attempts to locate a base
station. Doing so consumes
battery power and will
consequently shorten standby
time.
Change your location to one where
the network is accessible, or
temporarily turn off your phone.
You cannot
switch your
phone on.
Battery power has been
exhausted.

consecutive times.
Contact your service provider. If the
service provider provides the PUK
code of the SIM card, use the PUK
code to unlock the SIM card.
