You are still able to login to the web UI when there is no SIM card inserted. Connect your computer to the MR6400 and login to the web UI with domain name or IP address.

 

You can unplug the sim card and plug it back and repeat it few times; or you can hard reset the MR6400 by holding the reset button for 10s with SIM card inserted. 

 

Besides, you can change another SIM card and verify whether it can be detected.

@rikimaru 

Hi, have you seen this link:

[Troubleshooting] SIM Card not Found?

By the way, how long have you had the modem?

Most of the time, If the SIM card was not detected, the IP addresses are all “--”.

Could you please also send me a picture of the 3/4G status under the internet section?
