The nano-SIM measures only 12 x 9 mm, making it the smallest SIM card in the world.
At Apple’s request, a new generation of SIM cards has been developed: the Nano-SIM. By reducing a standard SIM card to about half its normal size, the company was able to deliver the iPhone 4, its thinnest smartphone yet.
The nano-SIM card offers a size of 12 x 9 x 0.66 mm, compared to the micro-SIM that measures 15 x 12 x 0.76 mm.
Advantages of the nano-SIM include a decrease in size by 52%, meaning more space in the smartphone, a larger storage capacity, but also increased security.
Word on the net is that the future iPhone 5 could feature this miniaturized version.
That would certainly fit in with rumors circulating earlier this year – ahead of the iPhone 4S launch – that Apple was readying a refreshed iPhone 5 with a significant change in industrial design and specifications.
