I remember when the iPhone 4 came out and it required a NEW SIM format (for GSM based iPhones). It required a Micro SIM. This wasn’t a problem if you were buying a new iPhone because it would have a new Micro SIM already installed. However, if you wanted to use a different SIM from another phone or carrier then chances are it was a full sized SIM that you would have to cut down to Micro SIM size. There were several good Micro SIM cutters on the market and I own a couple of them. I even traved with one in my suitcase in case I got to a country that I wanted to buy a pre-paid local SIM and needed to cut it down for my iPhone 4 or 4s. Once again we are faced with a new SIM format. Now the iPhone 5 and iPad mini uses a Nano SIM. This SIM is even smaller AND thinner than the Micro SIM. That of course poses a problem for those that want to move SIMs between devices. As to be expected there are now a few different Nano SIM cutters on the market. Some even come with sandpaper to sand the back of the SIM down to make it slightly thinner. I used one to cut down my AT&T Micro SIM down to Nano SIM size to use in my new iPad mini. My AT&T SIM is originally from my iPad 2 and is grandfathered in to an unlimited data plan. This is GREAT for streaming video on the road, so I wanted the ability to use this SIM in my iPad mini as well. Although this is not the cutter I used in the video, this is the one I’d recommend here.
Here’s a video on how the cut went:
