Mobile phone for multiple SIM cards
First Claim
1. A mobile phone for multiple SIM cards comprising at least a telephonic apparatus, a battery, and a rear casing for covering said battery and connecting with said telephonic apparatus;
- said mobile phone is characterized by that;
said rear casing has receiving capacity at least for loading of an electric circuit board, said electric circuit board has a plurality of connectors used for fixing a plurality of SIM cards (subscriber identification modules), said SIM cards each forms a parallelly connected loop connected through a connecting point provided on said electric circuit board;
additionally, said electric circuit board has thereon a soft bus line to connect an extension card which is inserted in the position where said SIM cards are originally located in said telephonic apparatus, so that the communication loop of said telephonic apparatus is communicated with said electric circuit board by means of said extension card as an interface;
said electric circuit board is installed thereon a manually moved switch on the contrary side to that loaded with said SIM cards, when said manually moved switch is switched to said loop of one of said SIM cards of any system, the state of combination of said telephonic apparatus is communicated in the close state with the one of said card loops of said system.

Abstract
A mobile phone for multiple SIM cards, wherein, a telephonic apparatus is used to select by switching among a plurality of communication services provided by various providers in the art of system communication. The mobile phone is provided on the rear casing of the battery or between the main machine and the battery of the mobile phone with an electric circuit board having a plurality of SIM cards each is able to connect via a bus line with an extension card functioning as a communication interface of the mobile phone with the electric circuit board and parallelly connected with each of the SIM cards on the electric circuit board to thereby form an open loop. A manually moved switch is provided on the loop, so that when the switch is switched to the card loop of any system, the state of combination of the mobile phone is communicated with the card loop of this system. Therefore, an object of providing a plurality of SIM cards for a mobile phone can be attained.
