The RT-MSR810-LME, RT-MSR810-LMS, RT-MSR810-LMS-EA, RT-MSR810-LUS, RT-MSR810-
LM-SI, RT-MSR810-LM-EA, and RT-MSR810-LM-EI routers support Micro SIM cards and provide
two SIM card slots. SIM0 (M) is the master slot and SIM1 (S) is the standby slot. Only one slot is
active at a time. As a best practice, use the master slot if you are to install only one SIM card. You
can use the
sim switch-to
command to specify the active slot. For more information about the
command, see

The SIM card slots on the RT-MSR810-LME and RT-MSR810-LMS routers support 2G/3G/4G
network mode provided by all carriers. The SIM card slots on the RT-MSR810-LUS router support
2G/3G/4G network mode provided by China Unicom and China Mobile, and 4G network mode
provided by China Telecom. The SIM card slots on the RT-MSR810-LM-SI and RT-MSR810-LM-EI
routers support 2G/4G network mode provided by China Mobile, 4G network mode provided by
China Telecom, and 2G/3G/4G network mode provided by China Unicom.
The SIM card slots on the RT-MSR810-LMS-EA and RT-MSR810-LM-EA routers support
