Hello
Please insert the SD card and then navigate to Settings => Storage and check SD card is listed there or go to My file => Local' if the SD card is not there then i suggest you try another SD card that you are sure it is working, if still nothing' you have to take the phone back to PEP store in exchange for another phone.
