Subscriber identity module card backup system
An apparatus for backing up the storage data from a subscriber identity module card will comprise said followings: the subscriber identity module card connector, a central processing unit, a serial electrically erasable programmable read only memory, the displays, the power supply and the inputting device. Firstly, inserting a first subscriber identity module card into a subscriber identity module card connector of the subscriber identity module card backup system is carried out. Then, a first storage data from the subscriber identity module card is extracted and treated to a memory whereby a central processing unit. Next, backing up the first storage data into the memory whereby said central processing unit is achieved. Sequentially, the first subscriber identity module card can be removed from the subscriber identity module card connector. Next, a second subscriber identity module card is inserted into the subscriber identity module card connector. Finally, the first storage data is duplicated from the serial electrically erasable programmable read only memory into the second subscriber identity module card in order to back up the first storage data from the first subscriber identity module card to the second subscriber identity module card.
