Description David Ward 2015-08-15 22:14:03 UTC 
Dell-branded Sierra Wireless modems will not come online without first sending a DMS Set FCC Authentication command. For more information: https://sigquit.wordpress.com/2015/02/09/dell-branded-sierra-wireless-3g4g-modem-not-online/

This issue was fixed in upstream ModemManager: http://cgit.freedesktop.org/ModemManager/ModemManager/commit/?id=a83d1c70b1f433bcb9a33b4cb1b5e3032050a104

I backported this commit onto RHEL 7 (ModemManager-1.1.0-6.git20130913.el7), and tested that a Dell Wireless 5808e modem now successfully connects to the network. Please add the attached patch to the RHEL 7 ModemManager package.

NOTE: This requires support for the DMS Set FCC Authentication command in libqmi (see blocking bug). This is a build dependency, as the command is part of the libqmi-glib API, so please adjust BuildRequires: accordingly.

Comment 11 Dan Williams 2016-07-19 15:11:38 UTC 
Integrated support for FCC auth is now present upstream in ModemManager as of f5cd7476f4bcd3961d408b603344ad5fff03e40d.  Requires libmbim 1.14+ and libqmi 1.16+
Comment 13 Vladimir Benes 2016-09-21 13:32:46 UTC 
David, could you please check with beta release (or anything newer) if everything works as expected? I think it's connected to bug 1253943 as well.
Comment 14 Vladimir Benes 2016-09-28 11:51:36 UTC 
Dan Williams verified that this is working well
