Hi, nomnom. Welcome to kioskea and hope my answer will do some help, even a little :) Well, if your photos were saved in your Nokia phone memory card instead of the SIM, then you have chance to recover the missing photos.
#1. Connect your Nokia phone (memory card) to a computer. Note: better take the card out and load it on the card reader and then insert to the USB port of the PC.
#2. Download the install this photo recovery program on your computer.

But you should remember - the more you use your Nokia memory card, the less likely you may be able to recover the photos! So STOP taking more pics or save data now. Best regards
