I just ordered the Nexus 5 and I want to use the sim that is in my Galaxy Nexus. (We don't have LTE coverage here). From what I'm reading the Galaxy Nexus has a regular sim (I can't remember now what it was when I got it) and the Nexus 5 takes a micro sim. How hard is it to cut down a regular sim to fit in a micro sim slot? What cutter is the best one?
