But seriously, it seems that those Micro-SIMs that the iPad take aren’t technologically that different from their bigger brethren. In fact all you have to do is cut some of the plastic off of the regular SIM to make it a micro-SIM, according to CNET.uk and their quote from the ETSI.
The European Telecommunications Standards Institute (ETSI), which sets the standards for SIM cards, tells us that except for the size of the plastic around the chip, micro SIM cards are identical to the SIM cards we normally find in phones.
And you were worried! Remember, if you decide to cut your SIM card, it ain’t going to go nicely back into your iPhone, mkay?
