Update:
We brought two of our boards (boards 3 and 4) to the problemmatic location. We
found that one board (board 4) connected just fine, while board 3 never would
connect successfully.
I ran the commands Aleksander suggested, along with the network start command.
Here are the results:
Board 3:

What is causing board 3 to consider the LTE service available and the WCDMA
service not, while board 4 has the converse, WCDMA server available and LTE
service not?

Hello Everyone,
Our LE910 modem and libqmi has been connecting successfully and working at
multiple sites. However, we consistently failed to connect at a new site in the past
day or so where there was a very strong signal (4 bars on a phone). Here are the
log messages from the qmicli connect attempt:
Mar 2 15:48:32 arm timed[292]: error: couldn't start network: QMI protocol error (14): 'CallFailed'
Mar 2 15:48:32 arm timed[292]: call end reason (12): (null)
Mar 2 15:48:32 arm timed[292]: verbose call end reason (2,201): [internal] error

Mar 2 15:48:32 arm timed[292]: 2016-03-02 15 48 32: system command qmicli -d /dev/cdc-wdm0 --wds-start-n*
*etwork=["11583.mcs"] --client-no-release-cid failed.
It appears the reason is that the CID release failed. Unfortunately I am too ignorant
to even understand what this means. I would appreciate if someone could explain
this and/or the other information reported.
