Upgraded the modem firmware and I now pass lte_lc_init:

Could it be the SIM card provided with the kit? It shows as "Not connected to any device" on nrfcloud. I also tried the LTE SIM Card from my own cell phone (not sure if it's even suppose to work on standard LTE) with the same result.

I believe that this is not an error with the zephyr message queue but the modem that actually answers "ERROR" to the command "AT%XSYSTEMMODE=1,0,0,0".
