I have a bunch of MicroSIM cards and wanted to use them on my unlocked Verizon iPhone 5 but was unaware how easy it was to get it cut and work! I cut my T-Mobile microSIM down (cut off the white parts, no gold off) and just shoved it in the SIM tray. IT WORKED! I tried the same thing with my older Verizon 4G LTE SIM cards as well! Note: I used a pair of regular office scissors.
