Actually, after reboot the feature was there again, and the output of the command is: EG06ELAR03A05M4G
However, I'm having trouble with the modem (#1 in use with SIM) seems to have a malfunction after a while of uptime. Then the GPS location is no longer updated, but Internet works. Is this a known thing?
I've just tried to re-apply the latest firmware to see if that helps. Any suggestions?
