This review is from: Aerb Nano Sim Card Cutter Mini /Standard & Micro to Nano Sim for iPhone 6 Plus iPhone 6 iPhone 5 iPhone 4, 4S and other Phones + Metal Tray + 2 Sim Adapters + Sand Paper, All in One Pack (Wireless Phone Accessory)
In case you don't know, here's how this works. GSM phones (like AT&T, T-Mobile, and most overseas carriers) use a "SIM" card. For a while, SIM cards came in one size, and that fit any phone. However, as phones started to get more and more sophisticated and manufacturers scrambled to fit more inside the device, the SIM card was targeted for size reduction. First came the Micro-SIM, which is still popular and in use today in many devices (such as the Samsung Galaxy S4). Then came the Nano-SIM, which is even smaller, and is used in the GSM version of the Apple iPhone 5, 5C, and 5S.

But here's the trick... aside from the size of the SIM, all three SIM cards are exactly the same. In other words, you can take a big SIM and cut it down into a micro or nano SIM size. The chip in the middle of the card doesn't get damaged and doesn't know or care how much plastic is around it.

I purchased this because I wanted to cut my AT&T Micro-SIM card down to Nano-SIM size for an iPhone 5, but still have the option to use the Nano-SIM in the Galaxy S4 by using an adapter.

Cutter: The cutter that comes in this kit is a very good, solid quality. It is hard metal and is built like an old fashioned metal stapler. You put your full size SIM (or Micro SIM in an adapter) in it, press hard, and out comes a nano. My only criticism of this product is that, since it is a PRESS, the nano SIM that comes out can be a little bit rough-around-the-edges (literally). I used this on a T-Mobile SIM and I had to sand the edges to get rid of some burrs. Also, a SIM card should have one corner cut diagonally so that you know which way to put it. After using this, it was a little unclear which corner was the angled corner because the corners came out a bit rough. It wasn't a huge problem, but it is something to be aware of. Another limitation of this press is that it doesn't allow you to create micro SIMs from full size SIMs. The output is only nano SIMs.

I was very pleased with the size-up adapters. My newly minted nano-SIM snapped into the adapter and worked perfectly in a phone requiring a micro-SIM (Galaxy S4). I liked these adapters over another version I purchased which did not secure the SIM in place and added to the thickness of the card. This kit comes with two size-up adapters: nano to Micro and nano to full. No micro to full was included.

Overall, I was very pleased with this product and I would recommend it to anyone needing to re-size a SIM down to or up from Nano size. The price is great, and the drawbacks for the little hand press are easy to overlook in light of quality of the product and its usefulness.
