Donald:
I found out that after the Cellular test issued network originated detach, the modem won’t be able to re-attach to the cell for a while (don’t know exact how long, but should be able to re-attach after several days). I found out that reset the modem will clear it and be able to quickly re-attach to the cell
I am not what command from the cell (network) that causes the modem to be “disabled” and wondering whether there is any AT command that other than reset will clear this condition?
I thin the firmware is latest version. Modem supports band 2,4,5, 17. And cell is configured to send band 17 signal. SIM card is from R&S test SIM card
Here is what I did after detach issued from the cell, reset modem and it re-attached to the cell:
