3. Preparation before Use
Installing the 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 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!
