To dial an emergency call
You can still dial an emergency call, even if the keypad is locked. Please enter the call
number directly and press the Send Key.
Can not connect to the network
Check whether the phone is in the CDMA network service area or move other places
to try again.
Can not receive a new message
Check whether the network condition is OK, and then check whether the Inbox is full.
If you turn off the Auto Delete Inbox function, you may not receive new messages
when the inbox is in full status. You should delete some messages and change the
settings.
Can not establish Three-Way Call
Check the network condition and whether you have applied this service from your
network provider.
