If you’re like most people, you probably have an iPhone with a built-in SD card reader. But if you want to use an external SD card in your iPhone, there are a few things you need to know. First, make sure your iPhone is connected to the power supply and your computer. If it isn’t, it may be damaged if the battery dies while using the SD card reader. Second, make sure that yourSD card is formatted correctly. This means that it has been created as FAT32 or FAT16 and not RAW or JPEG. If it isn’t, your iPhone may not be able to read it. Third, insert the SD card into the SD card reader on your computer and connect the phone to the computer via USB. The phone should now show a message saying that the SD card has been inserted and is now in use. If everything goes according to plan, you’ll see a list of files on the SD card when you open Finder or another file manager on your computer.
