Hi Cam. Not sure specifically on that phone but this video of a similar Figo model might help.

In that video she removes the back of the phone to reveal the SIM card slot. See if your Figo phone has slots in a similar position.

Many phones are real tricky to open. You have to jam your fingernails and hold your tongue just right. Good luck.

p.s. This video demonstrates how to open the back of several different models.
