We already know that Apple is trying to develop a smaller SIM card for mobile phones, and have it adopted as the industry standard SIM card for all devices, as we heard a while back from Orange who confirmed that they were working with Apple on the new SIM card.
We also heard that a number of other mobile carriers were working on this new SIM card, and now AT&T have confirmed that they are working on it, although they did not mention Apple specifically and just said that they were ‘wrking with the industry’.
A smaller SIM card than the current microSIM that is used in the iPhone 4 would give Apple more room inside the device, which would allow them to make it slimmer and smaller or add in more hardware in the space they have saved.
The current microSIM found the the iPhone 4 is smaller than the SIM cards used by the majority of smartphone manufacturers, and having an industry standard SIM card size which is much smaller than the existing one would make it easier for the mobile operators as well as the smartphone manufacturers.
