When you have connected your phone to a computer using the USB 
cable, you can select Mass storage to manage the files stored in the 
phone memory or microSD card using the computer's file manager 
application. 
The phone memory and its microSD card are displayed as removable 
disks on the computer. You can perform the following operations: 

1. 

Double-click a disk to open it. 

2. 

Copy, paste or delete files. 

3. 

Disconnect the phone from the computer. 



 

Ensure that you connect and disconnect the USB cable 
properly. 



 

Do not run the formatting command on the computer to 
format the phone memory; doing so may permanently 
damage the phone memory. 



 

You can transfer data and charge the battery by 
connecting the phone to the computer with the USB 
cable. 

 

The personal identification number (PIN) protects your SIM card from 
unauthorized parties. 
If you incorrectly enter the PIN a specified number of times, the PIN 
is blocked and the phone prompts you to enter the PIN unblocking 
key (PUK). If this occurs, enter the PUK to unblock the blocked PIN.   
If you incorrectly enter the PUK a specified number of times, the SIM 
card will become permanently invalid, and you must contact your 
service provider for a new SIM card. 
Both the PIN and the PUK are provided with the SIM card. For details, 
contact your service provider. 
The PIN lock for each SIM card must be configured separately.
