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
Unable to switch on
1. Does the battery have enough electrical power?
2. Is the battery placed correctly?
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. You
may be in a weak reception area. Move and try again
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.
No ringtone on incoming calls
1. The Silent profile has been selected in User Profiles.
2. The ringtone volume is too low. Set the correct volume through
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.
Photos taken are distorted
The subject may be too close for the camera lens.
The picture selected as wallpaper is only
partially visible
The size of the photo is probably too large. The recommended size is
320x240.
Service menu is not accessible
Maybe your SIM card doesn't support Services function.
