Apple changed the game with the iPad and the iPhone 4 when they introduced Micro SIMs. Something that other manufacturers still fear to implement. The Micro SIM cuts down the size of the regular SIM card to save precious space inside the handset for other things. While Apple is probably the only one currently dealing with Micro SIM’s, it seems that they aren’t content with that.
Reports suggest that Apple wants to shrink the size of our SIM cards further. The European telecoms standards body (ETSI) seems to have confirmed that Apple has proposed a new standard for smaller SIMs and the same is currently being debated. While industry players may or may not agree, if this gets through at all, this would be a major change.
Not sure if our Micro SIM cutters would still work, but every mm of space inside a smartphone is now being used to house chips, sensors and battery. The trend surely has to continue.
