Unfortunately: this stanza is only suitable for punch out from a full-size SIM card nano-SIM. If this works, I have not tried. I assume that this SIM card will break down because of pressure exerted as opposed to micro-SIM, directly on the electronic components.
Anyway: if you wanted to make a Micro SIM to nano-SIM, then you would have to have a metal adapter, so it is on the rudimentary manual outside of the package. This adapter not included. Instead, two bent plastic frames are in the process by which a nano-SIM could be brought to the size of a micro-SIM or a normal SIM card. Because these frames are bent, they could be used, however, probably also not.
All in all is a clear recommendation: buy in no case !!!
