Abstract

A cellular telephone into which several SIM cards can be inserted is disclosed, thereby permitting the use of several telephone numbers without it being necessary to change the card manually each time. This offers two significant advantages: time savings over the conventional procedure for replacement of one SIM card with another and avoidance of damage to the SIM card microchips and mounting inside the telephone caused by repeated replacement of the card.

Description

Description
MULTI-SIM CARD GSM CELLULAR TELEPHONE
The device, as illustrated in the attached figures, consists of: a cellular telephone (A-Fig.1), which contains a switching circuit (B-Fig.2) that makes it possible to switch the wires (Cl,C2,C3-Fig.2) leading from the various microchips (D1,D2,D3-Fig.2); the switching circuit contains a multiplexer (MUX-Fig.3) with four five-line inputs formed, in turn, by five multiplexers with four one-line inputs connected in parallel and commanded by the two inputs XI and X2 in the way described in the MUX truth table (Fig.4): one ofthe three microchips is selected according to the logic value assigned to imputs XI and X2; an ISO format adaptor (E-Fig.6), containing three or more windows (F-Fig.6) into which the microchips can be inserted (G-Fig.6).
The purpose of this device is to switch rapidly from one telephone line to another without mechanical intervention.

Claims

Claims
