Possible causes
• The network signal is too weak at your current
location, for example, in a basement or near a tall
building, because wireless transmissions can not
effectively reach it.
• The network is busy at the current time (for
example, during peak times, there may be too much
network traffic to handle additional calls).
• You are too far away from a base station for your
service provider.
• Poor network trunk quality on the part of your
service provider.
• Poor local telephone line quality.
• Your service provider does not support these
features, or you have not applied for services that
provide these features.
• The battery or battery charger is damaged.
• The phone‟s temperature is below 0° C or higher
than 45 ° C.
• Poor contact between the battery and charger.
• 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.
• 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.
• Battery power has been depleted.
• (U)SIM card malfunction or damage.
