I found I need an adapter for a Micro SIM card.
I took some time to measure the size of a Micro and an ordinary SIM card, and figured out the shape of an adapter:
sim-adapter.dxfThen, I simply cut this out from a container box I found to be roughly the same thickness, 0.8mm.
It works for me, but be aware that the info here is not verified by an expert in the field.
all units in mm.
