2.3 Unlocking the SIM Card
To avoid illegal use, the SIM card is enciphered with PIN (personal
identification number) as a measure of protection. When this function is
ON and you have already set a PIN code, you need to type in PIN code
every time the handset is switched on, in order to unlock SIM card and
use the handset.
You can turn off the SIM PIN code. Yet in this situation, the SIM card
can't prevent illegal use.
Enter PIN code, press arrowhead icon to erase typing errors and press
the check mark icon to end typing. For example, if the PIN code is set
as 1234, then type "1234" and then press the check mark icon.
The SIM card will be locked if you type in the wrong code three
consecutive times. The handset will then inform you to type in the PUK
code.
Attention: Your network provider will set a standard PIN code (four to
eight numbers) for your SIM card. It is recommended that you change
the code into a personal code as soon as possible.
2.4 Connecting to the Network
When the SIM card is successfully unlocked, the device will
automatically search for available networks (the lock screen shows
searching). The device will show the information of the network
provider, and the status bar will show the signal strength and the
network status once the device is successfully connected to a network.
Note: If the lock screen says "Emergency Call", it means
that you're out of network coverage (service coverage) or
your card is not valid, yet you can still have emergency calls
based on signal strength.
