Device comprising a subscriber identity module interface and associated method

Abstract

The invention relates to a device comprising an interface for subscriber identification module, a first subscriber identification module connected to said interface; a connector suitable for connecting a second subscriber identification module to said interface when the second module is present in the connector; a presence detector configured to generate a presence signal of the second module in the connector; an inhibition circuit for inhibiting the first module according to the presence signal, the device being configured to operate with the second module when the first module is inhibited, the inhibiting circuit being configured to inhibit a module by setting a data input/output of said module to a high impedance state, by applying a signal corresponding to an active state to an initialization signal input of the module to be inhibited. The invention also relates to a method, a computer program product and a program storage medium.
