For the phone with a removable battery, it supports dual SIM cards and SD/TF card at the same time. But for the phone with a build-in battery, as SIM 2 and SD/TF card share the same slot, so you can use dual SIM card or use 1 SIM card and 1 SD/TF card at the same time.

* If it is with a removable battery, please open the back cover (open it from the small gap）and tear away the insulating paper, then you should charge it at least 4 hours and turn it on. (This is due to shipping need).

* If it is with a built-in battery, then just need to charge it more than 4 hours, then it can be turn on, as it may be out of power for a long transition.

* If this phone still could't be turn on，please connect the USB port of the computer to charge the phone，then charge it for more then 4 hours ，conform it could be turn on or not.

In this case, you can uninstall some useless apps first, then insert the SD/TF card, then change the default write disk to the SD card (steps: storage - SD). Besides, you can move most apps to the SD card except system apps.
