Earlier, a reader by the name of ShadowKnight was concerned
about the risks of damaging a precious SIM card by having it
trimmed by someone else.
He is not wrong to say that. But only if you misjudge the cut
and do it by hand using scissors or penknife. In fact, someone I
know used her mom's meat knife (!) to cut her own card. While she
didn't damage her SIM card, she misjudged her cut by a few MM and
ended up being hurt by the knife. That's even worse!
Anyway, back to the ShadowKnight's concern -- how it works is
there is a special slot in the cutter that I use that's shaped
exactly in the size of an actual MicroSIM. All that's needed is to
insert your SIM card into the slot, and the cutter trims the card
exactly, right down to the millimeter, into the size of a MicroSIM.
Only the plastic border gets trimmed away. It's like how you shape
mooncakes in a mould and then pop them out in the right size.
The interesting thing is, I helped someone with his SIM card
last week, and trimmed away the plastic border and a little of the
outer metal contact and it still worked. Here's why - all the
neccessary, critical info is encoded only on the inner surface, at
specific areas, of the SIM card's circuit board (the gold part) and
the cutter I use is designed to avoid those sensitive areas.
As a discerning person myself, I'd be concerned if I were
ShadowKnight. But I also hope my explanation helps you understand
little about how things work.
I also want thank those who've supported this little intiative
of mine. It's something that I thought would save you a bit of
money, time and effort.
Meanwhile, have fun with your Apple toys :)
Cheers!
