BGR

According to a recent Financial Times report, European mobile carriers have started placing multiple orders for new nano-SIM cards in anticipation of an iPhone 5 launch which will reportedly use the miniature cards. The move should help ensure that carriers don't run out of cards like they did when Apple switched to the microSIM format with the original iPad and iPhone 4.

What You Need To Know:

- The nano-SIM is 40% smaller than the microSIM.
