In the Nano SIM, I'm not so sure. On the Internet and the network operators will be spoken by different thicknesses of the SIM card. What indeed is true. The Nano card is 0.09mm thinner than the Micro SIM.
But the SIM Cutter a Nano SIM is if you look more closely engaged with the whole issue, the only way to get out of SIM cards that have the "micro" chip to punch out. Not every provider has a nano-SIM in the offer. Now what makes the customer with a micro-SIM?
Exactly, he punches himself a nano-SIM for his smartphone (Samsung Galaxy S6, S6 Edge Samsung Galaxy, Samsung Galaxy Alpha, Samsung Galaxy A3, A5 Samsung Galaxy, Samsung Galaxy S Gear, iPad mini, iPad Mini 2, iPad Mini 3, iPad Air, iPhone 5c, iPhone 5s, iPhone 5, iPhone6, iPhone 6 plus, Amazon Fire Phone, HTC One M8, HTC One mini 2, HTC One M9, Sony Xperia Z3, Sony Xperia Z3 Compact, Nokia Lumia 830, Nokia Lumia 930)
However, the only difficulty is in such manual blanks that resulting chips connect between two or more contacts, which the SIM the first use damaged or destroyed. So careful sanding is called for.
