Install SIM Card
When registering mobile phone
number, you can apply for two different
phone numbers, two different mobile
phone network service providers and thus
obtain two SIM (Subscriber Identification
Module) cards.
With these two SIM cards, you can
use all functions of your mobile phone.
The SIM cards save the parameters
needed for communications and
personal data, including PIN (Personal
Identification Number) code, phonebook,
short message and other extra system
services.
Warning: Do not distort or scratch the SIM
card nor let it contact static, dust or
moisture. If it is lost, please contact
immediately your network operator for
14
help.
Before SIM card installation, please
switch off the mobile phone. The SIM card
is installed on the back of the mobile
phone.
Follow the following diagram to install
the SIM card. Please insert the host SIM
card into the SIM1 slot and the slave SIM
card into the SIM2 slot.
Note: If SIM card is inserted only into
the SIM1 slot, then only the host works;
likely, If SIM card is inserted only into the
SIM2 slot, then only the slave works. When
two SIM cards are inserted into the SIM1
slot and SIM2 slot respectively, you can
choose work mode freely as you wish.
Note: As the SIM card is small object,
keep it out of children’s touch or prevent
children gulping it!
