Most cases are designed for the sole purpose of protecting a smartphone from getting scratched. This latest case for the iPhone5/4S/4 has a second function. That is to provide an area to hold a pair of SIM cards allowing the iPhone5/4S/4 to be used with dual SIM cards rather than a single SIM card.

To get the dual SIM cards connected to the  iPhone5/4S/4 / a ribbon cable is provided that you insert in to the microSIM slot. This then folds around the back of the iPhone5/4S/4 to a place where the case holds them in to position.

The adapter provides a way to switch between SIM cards without switching the iPhone5/4S/4 off which is handy for times when you want to use more data for example, or switch to a SIM card that has more text MESsages available.
Lets say you have a unlocked iPhone5/4S/4 and posses more than one network simcard and wish to swap the network simcards around from diffrent providers be it any reason you like.

Currently by phyically switching network simcards manually can get complicated and become time cumsuming and can cause damage to the iPhone5/4S/4  sim gate and internal click in mechanism.

You may want to be able to swap simcard many times a day as and when you need to use your other network simcard.
