Troubleshooting
Before contacting after-sales service, perform the following simple checks. They may save you the time and
expense of an unnecessary service call.
Problems
Possible Causes

SIM failure
1. The SIM card is dirty. Clean it.
2. Reinstall the SIM card.
3. The SIM card is damaged. Replace it.
Poor signal
Check the signal strength icon on the screen. If the icon contains 4 bars,
the signal is at its strongest; if it is below 1 bars, the signal is very poor.
Unable to dial out
1. Maybe you have set Hide My Caller ID but your network
operator does not provide this service for you.
2. There are lots of interference sources in your neighborhood.
3. Maybe you have activated some call restriction function.
Unable to charge the battery
1. The battery may be over-discharged; so it requires a longer
charging period than normal.
2. Its performance has got worse; it is necessary to replace the
battery.
Unable to register to the network
1. Too weak signals or strong interferences.
2. SIM card not properly installed. Bad contact or SIM card
damaged. If the SIM card is broken, please contact the network
operator to replace it.

User Profiles.
The phone prompts you to enter your PUK
code
The incorrect SIM PIN has been entered more than 3 times and the SIM
is now locked. Please contact the network operator.
Photos taken are too dark
1. Brightness is set too low.
2. Ambient light is poor.
Photos taken are unclear
1. Check if your subject is moving too fast.
2. Maybe the phone slightly moved while the shutter was open.

partially visible
The size of the photo is probably too large.
