No. Your iPhone uses internal flash memory instead of an external storage device like a microSD card.
If you’re moving from Android to iPhone, make sure the contents of your microSD card will fit on your new phone. With an iPhone, you can choose from three different storage capacities: 32GB, 128GB and 256GB.
You can also look into iCloud, which offers storage ranging from 5GB to 2TB. Get details on iCloud, which is accessible from any phone.
