2.1.11.4 SIM Switch
The UICC/USIM/SIM interface lines may be connected to an external SIM card multiplexer con-
trolled by the SIM_SWITCH signal as shown in Figure 25. Thus, it becomes possible to switch
between two networks/subscriptions each with their own UICC, and maybe different connec-
tion speeds. Please note that hot SIM insert/removal is only possible on the first SIM interface.
Also note that the SIM_SWITCH can be used to switch between a SIM and the embedded op-
tional eUICC interface as described in Section 2.1.7.
The SIM_SWITCH signal is controlled by AT command (see [1]).

2.1.11.5 SUSPEND Mode Indicator
When all conditions for entering into SUSPEND mode are fulfilled, the SUSPEND_MON signal
changes from high to low, indicating that the module has entered its SUSPEND mode.
When leaving the SUSPEND mode, the URC “^SYSRESUME” is triggered, and the SUS-
PEND_MON signal is set to high again.
SUSPEND_MON usage can be enabled/disabled by AT command (see [1]: AT^SCFG “GPIO/
Mode/Suspend”).
