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 with 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!
Install Memory card

install a memory card (This mobile phone use T-FLASH card.)

lock, insert the T-Flash card into its slot, restore the lock and then put back the battery restarting the
