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 verifies the availability of the 
SIM Card.   

Then, the screen shows the following:   
Enter PIN1 —— if your 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. 

Notes： 
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.   

The PIN 1 (personal identification 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.

  Enter your PIN1 code. Clear the incorrect digits by using the right soft key, and press OK for 

confirmation. e.g. if your PIN1 is 1234, 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 PUK1 code, do not try. Instead, contact 
your network service provider. See “Safety settings”. 
Note: your network service provider sets a standard PIN1 code (4 to 8 digits) for your SIM card. You should 
immediately change this number. See “Safety settings”.   

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”). In this case, the unauthorized 
use of your phone cannot be protected.   

If you forget your phone password, you must contact the retailer or local authorized service center to 

unlock your phone.
