Troubleshooting
Security Problems
The SIM card's PIN code is
blocked.
System Problems
Battery does not charge
The device does not power on. The battery has no charge.
Shortened standby time.
Messaging problem
Unable to send or receive text
messages.
Possible causes
You have entered an incorrect PIN
code three consecutive times.
The battery or battery charger is
damaged.
The ambient temperature is below 0 °C
or higher than 40 °C.
Poor contact between the battery and
charger.
The duration of standby time is
affected by your service provider's
system configuration. The same device
used with different service providers'
systems does not have the same
duration of standby time.
If you are not able to connect to the
network, the device continues to send
out signals as it attempts to locate a
base station. Doing this consumes
battery charge and consequently
shortens standby time.
Your device is in airplane mode with no
wireless connectivity.
The network signal strength is not
strong enough.
Possible solutions
Contact your service provider
to get the PUK code.
A possible cause for this
could be the use of incorrect
power adapter. Use only the
power adapter that shipped
with your device.
Adjust the battery charging
environment to avoid
extreme temperatures.
Check all connectors to
ensure that all connections
have been properly made.
Charge the device.
If you are located in an area
where the network signal is
weak, move your location to
the area where the network
signal is strong or temporarily
turn off your device if needed.
Change your location to one
where the network is
accessible, or temporarily
turn off your device or set it
to airplane mode.
Slide the status panel down
and then disable airplane
mode.
Try moving to a different
location for better signal
reception.
