Before SIM card installation, please switch off the mobile phone. The SIM cards must be inserted in the back of the
phone, after removing the battery. Insert the SIM cards in their slots with the gold contacts facing down and the
notched corner facing outwards. Insert the main SIM card in the SIM1 slot and secondary SIM card 2 in the SIM2
slot. See the diagram below.
Note: if a SIM card is inserted into the SIM1 slot only, then only the host works; likely, if a SIM card is inserted
into the SIM2 slot only, 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!

Memory Card Installation
Installing a Memory card
As the mobile phone does not have enough storage space, to use some functions, you need to install a memory
card (this mobile phone use T-FLASH cards.)
To install a T-FLASH card: power off the phone, open the back cover to remove the battery, insert the T-Flash card
into its dedicated slot (underneath the SIM cards' slots), and restore the battery and the cover before restarting
the mobile phone.
