T-Mobile Cell Phones: How Do I Insert Or Remove The Memory Card On My SGH-T479 Phone?
Place the microSD card into the slot (as shown) and push slightly
with your finger until you hear a click. Ensure that the memory card contacts
face downward and the card is placed so that the indentations on the card
face the same direction as those illustrated.
Push the memory card with your finger a second time to eject
it from the slot.
