Use a compatible SD card reader for iPhone
Connect the reader to your iPhone’s Lightning or USB-C port
Insert the SD card into the reader
Open the Files app on your iPhone
Tap Browse if needed
Select the connected SD card under Locations
View, copy, move, or import files from the SD card
Use the Photos app to import photos and videos if prompted
Safely eject the SD card reader before unplugging it
Ensure the SD card is formatted in a supported file system such as exFAT, FAT32, or APFS-compatible media for best results
Charge your iPhone if the reader requires more power than the phone can provide
