Insert your Micro-SIM Card into the hole you cut out of the SIM.
If the Micro-SIM doesn't fit, you may need to cut away more plastic with the knife to enlarge the hole.
If you cut the hole slightly too big, put a piece of tape over the back of the SIM-Card (the side without the gold contacts) to hold the Micro-SIM in place. Trim away any excess tape with the knife.
