Nano-SIM standoff with Apple against Motorola, Nokia and RIM

Nokia, Motorola and RIM (backed by Google) are concerned that Apple might ultimately own the patents to the 'nano-SIM'. There have also been cries of unfair play by Apple in its attempt to gain more votes, as the European Telecommunications Standards Institute (ETSI) plans to vote next week.

A nano-SIM would be 15% thinner with a 30% smaller footprint at 12x09x0.646mm. Nokia claims its nano-SIM design has "significant technical advantages" as Apple's version requires a tray, as present in the iPhone and iPad. However, Apple's design is already backed by most European operators.

Currently, Apple is trying to increase its number of votes in the ETSI by wanting to register 6 different subsidiaries. Each subsidiary would be capable of having as many as 45 votes. Nokia currently holds the largest number of votes at 92.

The first SIM card was about the size of a credit card made in 1991. Then came the mini-SIM, currently the most used version of the card, at 25x15x0.76mm. The micro SIM currently used in the new iPhones and Nokia's Lumia is 12x9x0.76mm in size.
