Convert a micro-SIM into a normal SIM card, just a knife without adapter




Sometimes you’re stuck with a brand new microSIM that you can’t use in your phone, because you need a normal form factor SIM, but maybe you had this chance to activate a special promotion that only came in microsim format.

Well do not despair, you can get a normal SIM (-ish) from a microSIM, just DON’T remove the microsim from its matrix just yet!
