Post the complete output to the following commands:
sh cell 0/4/0 hardware | i PRI version
sh cell 0/4/0 radio
Now, in a text file, please paste and attach the output to the command "sh cell 0/4/0 radio history all".

This is output from your command . If I plug all antenna on router status RSSI show unknow.
#show cellular 0/2/0 hardware | in PRI version
PRI version = 0811-111, Carrier = Generic PTCRB
OEM PRI version = 0811-111

C1101-AIS#show cellular 0/2/0 ra
C1101-AIS#show cellular 0/2/0 radio

Current RSSI = -92 dBm
Current RSRP = -124 dBm
Current RSRQ = -13 dB
Current SNR = 0.8 dB
These numbers do not look good.
Either relocate the router to a location with better LTE coverage, get a better antenna (like 5G-ANTM-O4-B) or talk to the provider.
