This one is more difficult than cutting your sim to micro sim. Because you have to make an “adapter” for your micro sim. The size of a regular sim is 15mm x 25mm.

What you need to do is get a regular sim and trace it on a card or hard plastic that has the same thickness of your micro sim. Then cut a slot in between (like in the image below) so that your micro sim would fit in the hole. That’s it! Simple but making a hole in between is the difficult part.

    I can hardly describe how imprecise this description is, Jeff.
    Not only do you have two different sets of circuit, you give no dimensions of one SIM’s edges from the other’s.
    Look at your two graphics in the process: one’s centered the circuit in the markings; the other’s offset one way. Which is it? By how far if assymetric?
    One’s referenced to an edge in the other direction; the other’s well inside an edge. Which is it?
    Dimension lines?
    Back to the drawing board – literally.
    I am without speech.
