Nokia 220 Dual SIM - Why can't my computer find my Nokia phone's mass memory card?

Connect your phone to your computer, and select: 

  • Mass storage to see your phone's mass memory on your computer. If you haven't inserted a memory card, you're asked to insert one.                                                                                              
  • Charging only to use the charging mode.

If you select Charging only, or haven't selected either of the options, your computer can’t find the mass memory card.
