You must insert a valid SIM card before using the phone. SIM card is 

the key to the digital GSM network. 

All the relevant information and your call established of a network 

connection are recorded in the SIM card initialization of the metal surface 

area; meanwhile the names, phone number and SMS stored and received 

are also recorded in the phone book of your SIM card. SIM cards can be 

removed from your phone and put it into any GSM phone to use (a new 

mobile phone automatically read the SIM card). 

In order to prevent loss and damage from the card information, you 

should avoid touching the metal surface area, and keep SIM card away 

from electricity and magnetism place. Once the SIM card is damaged, 

you can not enter the GSM network.

 

Note: Be sure to remove SIM card after the phone off. There is 

absolutely prohibited in the case of an external power supply connected 

to insert or remove a SIM card, or SIM card may be damaged.
