SIC-4G-CNDE, SIC-4G-CNDE-SJKXXX2,

Installing a SIM card
The SIC-4G-CNDE, SIC-4G-CNDE-SJKXXX2, SIC-D4G-CNDE, and
SIC-D4G-CNDE-SJKXXX2 interface modules use micro SIM cards.
The SIC-4G-CNDE and SIC-4G-CNDE-SJKXXX2 interface modules
provide two SIM card slots, but only one is active at a time. If you install
SIM cards in both slots, the SIM1 slot is active and the SIM2 slot is in
standby state by default. To perform an active/standby switchover, execute
the
sim switch-to
command. For more information about the command,
