The new iPhone arrived using a new chip standard, the Nano-SIM. Even smaller than the Micro-SIM used in iPhones 4 and 4S, the new chip gives more space for internal components, enabling even thinner and more battery-powered devices, such as the iPhone 5.
From left to right: Mini-SIM (original iPhone, 3G and 3GS), Nano-SIM (iPhone 5) and Micro-SIM (iPhone 4 and 4S).
Because it is so small, some people imagined that it would be impossible to cut their bigger brothers and fit them in the side chip tray of the new Apple cell phone. Because the CNET got a Nano-SIM in advance, from the operator StarHub (from Singapore), and performed some tests to answer: after all, can you cut a Micro-SIM chip and transform it into a Nano-SIM?
Perhaps. Only 0.67mm thick (about 0.09mm thinner than Micro-SIM), the biggest challenge in cutting the old pattern is something that CNET considers it possible, but to decrease its thickness.
Assuming that the side tray of the iPhone 5 accommodates chips with 12.3 × 8.8 × 0.69mm the dimensions of the Nano-SIM, to make a 15x12x0.76mm Micro-SIM fit inside the new phone it will be necessary to cut it and still sand it. And, in the tests performed by CNET, it was relatively easy to achieve these dimensions by sanding the plastic back of the Micro-SIM.
But since no one has an iPhone 5 to test and see if an adapted Micro-SIM works and if it really is necessary to make it thinner, I advise those interested in a new iPhone to confirm with their operator when the Nano-SIM chips will be available, to avoid headaches. Vivo reportedly started selling them in Brazil last weekend.
