You can turn off the SIM PIN code. Yet in this situation, the SIM card can't prevent illegal use.
Input PIN code, press arrowhead icon to erase typing error and press OK to end typing. For
example, if the PIN code is set as 1234, then type "1234" then press OK.
The SIM card will be locked if you type in wrong code for three times continuously. The
handset will inform you to type in 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.
2.5 Connection to Network
When the SIM card is successfully unlocked, the handset will automatically search for
available network (the lock screen shows searching). The handset will show the information of
the network provider, the status bar will show the signal strength and the network condition once
the handset is successfully connected to a network.
Note: If the lock screens shows "Emergency", 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.
2.6 Charging the Battery
Ensure the battery inserted in the handset. To charge the battery, plug in the charger
connector at the bottom of your phone (USB interface) and then plug the other end into an AC
power socket.
