now its a nano sim. It works just fine. I purchased my I5 at full cost for my agent line and they wouldnt let me activate it till further notice through verizon. I pulled my micro sim out of my S3 and lined it up. Cut it down and slid it into my I5. It worked perfectly. The claims of it being too thick are not an issue either. Not sure if others have done this yet, or questioned the process.
