Installing the microSD Card
Phone lock
The phone lock protects your phone from unauthorized use. The default
phone lock code is 1122. You can change it into any numeric string of 4
to 8 digits.
If the phone lock function is enabled, you need to enter the correct
phone lock code when the phone is powered on or in the standby mode.
Connecting to network
After SIM card is successfully unlocked, the phone will automatically
search available network (with searching showing on the screen).
Once the connection is made, the name of the service provider will be
displayed on the lower right part of the text and graphic area. At this
time your phone has been connected to the service network.
Note: If the screen prompts “Emergency “, this means you have moved
out of the normal network coverage (service range) or your card has not
passed authentication, but you can still transmit emergency calls based
on signal strength.
