I have order my phone from ebay, it wont come with the sim remover tool. I only need to do this one time anyway. What else I can use to safely open the Sim door without struggling? Please think of something not too thin (would puncture the inside part instead of pressing it) and not too thick (could scratch and wide the opening) according to your experience. I haven't got the phone yet, so I have no clue on the size of that hole and how firm I need to push.. Thanks
