* Micro SIM placed in the adapter and inserted on the bottom of the punch
* SIM in the window on the bottom of the punch aligned carefully, so that the chip is not damaged by the stamping operation
* Punch lightly pressed to lock the SIM card in the adapter.
* Punch provided on the table and the lever depressed strong with momentum
* Punched Nano SIM falls down out
The Result:
Nano SIM is running without problem in the iPhone 5, and with the supplied adapter to continue as a Micro SIM in the iPhone. 4
I am absolutely satisfied.
For me, the Micro SIM adapter was (not of metal for stamping) slightly bent plastic. But with some feeling the adapter could push handle and press the nano SIM in the adapter.
