I think your referring to your micro SD card. The sim is what connects you to the network. Your mini sd card is used for extra storage such as pictures and music. Don't fret, you can definitely put the mini sd in your new w490. Just take it out of your nokia and into the moto.Don'tt forget to make sure your pics are saved to the sd (just because the sd is in your phone, does not mean they automatically save), and don't forget to save all your contacts to your SIM card. Good luck your phone.
