It's now two years ago, and the ticket had a different scope. But one of the answers from Nordic there was:
"This is because the spec mandates that if the device gets rejected by a network with reject cause #12, #13 or #15 (and does not find another network it can attach to), it must stay camped on that cell.
This means that the device will listen for broadcasts from the cell, which will increase the power consumption. The main purpose for this is so that the device can still make emergency calls"
With the new %FAECONF "5 - enables the deactivation of the UICC when the modem detects that it is in an area where no cells are available. The UICC is reactivated when a cell is found." I'm not sure, when that exactly applies.
In the past it seems, that if there is a cell, but the modem is rejected, this is still considered to be the case "cell is found". Could you please clarify, if that applies for "%FAECONF 5"?
Also not sure, what the scope of deactivation is. As in the old ticket (and the tickets referred there), quite a lot users are very surprised by
unintended power consumption during the inactive periods of the network search configuration. So, is the modem still kept receiving and only the UICC is deactivated? Or is the modem also put into sleep mode when the UICC is deactivated?
