What is a nano sim? (EN)
It emerged in the summer of 2012 that European operators were stocking up on 40 percent smaller ‘Nano SIMs’ as they tested this standard extensively ahead of the next iPhone’s September 2012 release date. The size of this nanosim is 12.3mm by 8.8mm. It is only 0.67mm thick, which is 15% less than the thickness of the microsim.
There was a bust-up over the nano-SIM in March when several firms including Apple were each promoting their own ideas for the tiny chip. Rival phone makers including Nokia, which proposed its own nano-SIM design, feared Apple would patent its nano-SIM blueprint and claim royalties from every other company using the standard.
In the end, the European Telecommunications Standards Institute named Apple’s Nano SIM proposal as the industry standard back in June. It is thought that Apple was lobbying for a tinier SIM card, due to space being at a premium inside the next iPhone – so engineers knew they would be in need of some extra room to squeeze components inside the thinner enclosure. For other handset manufacturers, the extra space could also mean more capacity is created for larger batteries or memory.
