It can be a great solution for anyone who buys a phone off-contract and wants to add AT&T service, who wants to transfer data service from an older phone to an iPad, or who wants to share a SIM among several devices.

But why bother with handiwork? Enter the Micro SIM Cutter, a handy SIM trimmer that looks like a stapler and works like a hole-puncher. This stainless steel trimmer lets you cut-out your own micro-SIM safe and easily. It smahes your normal-sized SIMs and spits out a streamlined micro-SIM. The tool ships with two micro-SIM adapters that turn your micro-SIM back into a regular-sized SIM, which is pretty nice.
