(a) TECHNICAL FIELD OF THE INVENTION 
       [0001]    The present invention relates to a portable electronic device and, more particularly, to a powerful mobile device that can be carried and operated with ease, scaled with flexibility, and comprised of various functions. 
       (b) DESCRIPTION OF THE PRIOR ART 
       [0002]    Handheld devices or mobile devices have become a widespread technology, almost everyone owns a handheld device. The major manufacturers do their best in the development of newer technologies to meet people&#39;s needs and desires. The mobile technology continues to progress from handheld devices with mono-color screen to the current handheld devices with colorful touch-screen. However, these handheld devices are all a device with a screen, a battery, a memory card, and so forth. If a user wishes to expand the capacity of the battery or the memory card, he or she should buy another one with larger capacity to replace the original one. If a user wishes to have two separate numbers for different purposes, he or she should carry phones at the same time, and this may bring inconvenience. Furthermore, the two phones cannot backup for each other. 
         [0003]    Currently, there is a handheld device, commonly known as “Dual SIM Dual Standby (RSDS)”, which contains two SIM cards being active simultaneously, so that a user can use one handheld device of the type to operate two separate numbers at the same time without requiring to carry two different devices. However, when one SIM card is busy, the other one will not be reachable. 
         [0004]    Thus, there is a need for further improvement on the existing handheld devices to allow a device to be operated on two different numbers at the same time and be carried with ease.
