Welcome to Android Central! What phone do you have? Are you sure the card is fully seated in its slot? With most SD card slots, you'll feel the card click into place when it's in all the way.

Are you sure the card is formatted? Try inserting the card into your computer, using a fullsize SD card adapter.
