2.1.4.1 SIM_SWITCH Line
As an alternative to connecting the module’s two SIM interfaces and switching between these
interfaces by means of AT command, it is possible to connect the first of the module’s SIM in-
terfaces via an external SIM switch that in turn provides access to a further SIM interface.
Figure 7: External UICC/SIM/USIM switch
The module’s GPIO26 line can in this case be configured as SIM_SWITCH line in order to con-
trol the external SIM switch. A low state would then indicate the usage of the first SIM interface
(SIM1A), a high state would indicate the usage of the second interface (SIM1B).
The configuration of the SIM_SWITCH (GPIO26) line is done via AT command, is non-volatile,
and available after the next module restart.
