This punch can not be so cheap, so eroded edges that will take no SIM slot no fun. The adapters are total crap, too shallow, even original Micro SIM not hold. Fortunately, I have tested it with an old SIM that mattered, I then hammer out much better by craft scissors and this article went back again. Maybe there are better puncher, from this can only advise och. With only one SIM a template for marking, a craft scissors and a bit of intuition enough.
