SMS receive behaviour

[Daniel]

Hi all,

What is the supposed behavior when the modem device receives a SMS? The
message org.freedesktop.ModemManager1.Modem.Messaging.Added will be emitted
on dbus?

I am using the MMQt in order to handle SMSs in an embedded device. Sending
SMS it's ok.
But when I sent a message to the device, and I use the dbus-monitor in
order to see if the ModemManager sends the signal Added() there is no
traffic on dbus until I "reset" the modem using:
(disabling)
# mmcli -m 0 -d
(enabling) and after
# mmcli -m 0 -e

all messages that were sent to device will be received at same time and the
signals are emitted in the dbus, as follows:

signal sender=:1.3 -> dest=(null destination) serial=197
path=/org/freedesktop/ModemManager1/
Modem/0; interface=org.freedesktop.ModemManager1.Modem.Messaging;
member=Added
  object path "/org/freedesktop/ModemManager1/SMS/5"
  boolean true

Am I missing something?
How I can debug the process of receiving a SMS?

Follow some hardware info:
