You Can Totally Butcher Your SIM Card into a Nano-SIM If You're InsaneEric Limer9/17/12 1:10pmFiled to: PhonesiPhoneIphone 5SimsSIM cardNano-sim90EditPromoteShare to KinjaToggle Conversation toolsGo to permalink So let's say you're really excited to get a new iPhone 5, but unlike the average buyer, you're getting an unlocked one straight from Apple, and you're champing at the bit to bring it to your carrier. Problem: your current micro-SIM won't fit. What to do?! Well you can hack your normal SIM down to size, if you're desperate.Just like you could hand-modify a mini-SIM down to micro-size, it's not impossible to get a mirco-SIM (or a mini one) to fit the nano form factor. That doesn't mean it's easy. Mini to micro wasn't too bad because it was just a matter of height and width; you just have to do some chopping. Nanos, on the other hand, are 12 percent thinner than their predecessors. Fixing this problem is a little rough.
