Sprint doesn't use SIM cards...
Yes you can. I have at&t prepaid I then bought a curve. Put my sim in it boom it works.
I think you would have to do it all over again or put the SIM card back in the old phone and copy all text.

No, it does NOT need a sim card. In fact, Verizon doesn't even use sim cards. If you want to put music on your Voyager, you might buy a Micro SD card. ^ it does have a sim card people!!!! youtube blackberry pearl sim card!! under the battery!!
Unfortunately you cannot, they only way you can change sim cards is between the same phone models.
