Buy an adatper off of amazon - just make sure you use a piece of double sided tape to hold the nano SIM in the adapter because if it slips out even a bit when you go to insert it in or remove it from the device, it can ruin the SIM card reader of the device. Also, the noosy's don't fit the Verizon nano SIMs very well.
I use these and they fit the Verizon nano SIMs:

I usually have a few packs of these laying around for just that reason.
