If you have turned on your phone without inserting the SIM card, the phone will prompt
you to install the SIM card. With the SIM card already inserted, your phone automatically
verifi es the availability of the SIM card.
Then, the screen shows the following in order:
Enter PIN1—if you have set the SIM card password.
Enter phone password—if you have set your phone password.
Search for network—the phone searches for the appropriate network.
Notices:
If when you turn on the mobile phone, an exclamation mark appears on the screen and
does not disappear, this is possibly caused by misoperation, that is, you press the Power
key and the Volume Up key at the same time. Such misoperation activates the recovery
mode, hence the occurrence of exclamation mark. If you just turn off the phone, next time
when you turn it on, it will still come to the recovery mode.
Solution:
Press the home key when the exclamation mark and robot appear, a menu will pop up. Use
the menu key to select "reboot system now" to restart the phone.
2.4.3 Unlocking the SIM card
The PIN 1 (personal identifi cation number) secures your SIM card from being misused by
others. If you have selected this function, you must enter the PIN1 code each time you
turn on the phone so that you may unlock the SIM card and then make or answer calls.
You can deactivate SIM card protection (see "Safety settings"). In this case, the misuse of
your SIM card cannot be prevented.
• Press the Hang Up key to turn your phone;
• Enter your PIN1 code. Clear the incorrect digits by using the right soft key and press OK
for confi rmation. e.g. if your PIN1 is1234, please enter: 1 2 3 4
If you enter incorrect numbers for three times in succession, your SIM card will be locked
and your phone will ask you to enter PUK 1 number. If you do not know the PUK 1 code,
do not try. Instead, contact your network service provider. See "Safety settings".
Note: your network service provider sets a standard PIN 1 code (4 to 8 digits) for your SIM
card. You should immediately change this number. See "Safety settings"
2.4.4 Unlocking your phone
To prevent unauthorized use, you can set phone protection. If you have selected this function,
you must draw unlocking pattern each time you turn on your phone, to unlock the phone
and then make or answer calls. You may clear the unlocking pattern (see Safety settings).
