When the iPhone 4 debuted, it was (and still is, though less so) a very thin phone. At around 9.3mm thick and no removable battery the SIM card had to go somewhere, and Apple preempted the issue by creating the first widely-released phone with the new microSIM standard. Around 40% smaller than regular SIMs, and the same thickness, it hasn’t yet caught on all that much (the Motorola RAZR is the only other major phone release with a microSIM in Canada) but that doesn’t mean we have witnessed the end of slender SIM cards.
Behold the nanoSIM: a German company by the name of Giesecke & Devrient (G&D) has further reduced the size of the current microSIM by 20%, with a 15% reduction in thickness. If and when adopted — Apple has already applied to the European Telecommunication Standards Institute (ETSI) for approval of the new design — it will allow manufacturers to include even bigger batteries and camera modules without sacrificing thickness. While we don’t have a picture to show you, it will likely look like a miniature version of the microSIM we already know and love.
And anyone worried that their nanoSIM won’t fit in their current device? Well, as with the microSIM, adapters will be made available. Just be careful; these things are known to get lost.
