According to the Financial Times, the majority of European carriers have placed mass orders for nano-SIM cards. The reason for this is the next iPhone featuring the recently approved 4FF nano-SIM card design.
The new nano-SIM card is 40 percent smaller than the existing micro-SIM and has recently seen wide support with smartphone manufacturers besides Apple.
Motorola, Nokia, RIM and Apple have proposed a design for the nano-SIM to the European Telecommunications Standards Institute (ETSI), which eventually chose the Apple solution. Still, if the current micro-SIM is anything to go by, don't expect the new nano-SIM standard to become mainstream for at least another year or two.
