Hi all, The problem was in ModemManager, that basically was initializing just one channel that was used to ppp0 connections and when busy the SMS notification was not sent to ModemManager daemon instance.
This strange behaviour was "discovered" in 2015 September and was fixed in the stable version 1.4.12. http://lists.freedesktop.org/archives/modemmanager-devel/2015-September/002208.html Follow the thread that I opened. http://lists.freedesktop.org/archives/modemmanager-devel/2016-January/002540.html Thanks in advance. Best regards. -- Daniel Vaz
