In actual use, the standby time and talk time of the mobile phone
varies with the network status, working conditions and different
usage behaviors.
SIM card
Your network operator will provide you a SIM card which is the key
for your access to the digital GSM/3G network. Prior to using the
phone, you need to insert an activated SIM card in the mobile
phone.
All relevant information concerning network connection will be
recorded in the SIM card. SIM card can be removed from your
mobile phone and be used in any other GSM mobile phones (new
mobile phone automatically reads the SIM).
In order to prevent loss and damage to the information in the card,
you should avoid touching the metal area and keep it away from
electric and magnetic places. SIM card once being damaged, you
will not be registered to the GSM network.
Warning:
You must power off the mobile phone before removing the SIM
card. Inserting or removing the SIM card is absolutely
prohibited when the external power supply is connected,
otherwise the SIM card and mobile phone may be damaged.
1.4 Inserting the SIM card
Power off the mobile phone, remove the back cover and battery.
Insert the SIM card correctly in the card slot; finally install the
back cover and battery of the mobile phone.
