Many people with cell phones opt to buy a protective case to prevent damage. These cases come in two parts that snap together and hold your cell phone in between them. They snap together rather easily but provide a tight fit. Because of this, it can sometimes be hard to remove the case once it is snapped around your phone. There are several companies that sell plastic pry tools that are specifically designed to help remove cell phone cases. These tools won't cost anymore than a few dollars, and they can resemble anything from a guitar pick to a flat-head screwdriver.
Remove the belt clip attached to your cell phone case if one is installed. These clips will usually snap off of the case, but some of them may need to be twisted off.
Locate the seam running along the edge of your phone case where the two parts connect. The phone case has a front and back piece.
Slip your pry tool in the seam and gently pry the case apart. By simply twisting the pry tool, or sliding it around the edge of your case, the two parts of the case will fall apart.
