Hey,

Could you please provide some insight about the RPi, OS, Kernel etc.

3

Kernel: Linux raspberrypi 4.19.118-v7l+ #1311
OS: Raspbian GNU/Linux 10 (buster)
Raspberry Pi 4 Model B

Hey I am still running into this issue any likely fix I could try out?

I’m not quite sure what MCC:0, MNC:0 and PS stand for aswell

6

MCC = Mobile Country Codes
MNC = Mobile Network Codes
PS = Attached
Datacap could equal - LTE/4G/3G/CATM1/CATNB - the service designation as set by carrier.

Check you’re using the right APN for this service by carrier.
Check your antenna connection to the LTE terminal on the board & insure correct antenna for service type.
Check SIM for correct service type, active in carrier network (ready for use), check for damage, dirt/oil, etc.
clean, reinsert check fit & connection.

IF this is your first LTE/IoT hat you may want to try connecting w/PPP first just to validate carrier, connection, signal & SIM.
And of course make sure you’ve got a high quality low noise, 5VDC capable of at least 2A.

Post back your findings.

Thanks
