Installing a 4G SIM card 
 
CAUTION: 
•  Do not hot-swap a 4G SIM card. 
•  To avoid damaging the SIM card slot, do not use excessive force when installing a 4G SIM 
card. 
•  To avoid slot damage, make sure the SIM card is flush with the card tray when a SIM card tray 
is used. 
 
The RT-MSR810-LM, RT-MSR810-LM-CNDE-SJK, RT-MSR810-W-LM, RT-MSR810-LM-HK, RT-
MSR810-W-LM-HK, RT-MSR810-LM-GL, and RT-MSR810-W-LM-GL routers support standard 
SIM cards. 
The RT-MSR810-LME, RT-MSR810-LMS, RT-MSR810-LMS-EA, and RT-MSR810-LUS 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 Layer 2—WAN Access Command Reference 
in H3C MSR810[2600][3600] Comware 7 Command References. 
To install a 4G SIM card: 
1.  Remove the screw on the 4G SIM card slot cover and take off the cover. 
2.  Insert the 4G SIM card into the SIM card slot along the guide rails. 
3.  Reinstall the cover and fasten the screw on the cover.

Installing a Micro SD card 
 
CAUTION: 
To avoid damaging the Micro SD card slot, do not use excessive force when you install a Micro SD 
card. 
 
Only the following routers support Micro SD cards:
