Several manufacturers offered proposals for a new, smaller SIM card. This included submissions from Nokia, RIM, Motorola and Apple. Today, ETSI (European Telecommunications Standards Institute) selected Apple’s proposal for a new 4FF nano-SIM standard. The card will help manufacturers in the race to produce thinner and smaller phones.
The fourth form factor (4FF) card will be 40% smaller than the current smallest SIM card design, at 12.3mm wide by 8.8mm high, and 0.67mm thick. It can be packaged and distributed in a way that is backwards compatible with existing SIM card designs. The new design will offer the same functionality as all current SIM cards.
In addition to manufacturers, major mobile providers were also involved in the decision.
