Question USSD not working after upgrading to Ubuntu 14.04 from Modem Manager Gui


I use Modem Manger GUI for executing USSD commands for getting information about balance, validity etc. It worked fine in Ubuntu 12.04 Precise. However after upgrading to Ubuntu 14.04 Trusty, I found that when I send USSD command, I get a timeout error, but SMS, network traffic and all other tabs in Modem Manager GUI work fine. The Internet is working as well. Only somehow the ussd commands are not working. I have tried increasing the timeout (upto 40 sec), changing backends as posted here, and using PrepaidManager and mmcli commands from terminal. However, all show the same timeout error.
Modem : ZTE corporation MF190 (from ModemManger GUI).

Edit :
Here are the results of mmcli commands. I found the commands here.
Code:
subhraman ~:~> mmcli -m 0 -e
successfully enabled the modem
subhraman ~:~> mmcli -m 0 --3gpp-ussd-initiate="*111#"
error: couldn't initiate USSD session: 'Timeout was reached'

Upload following command output

Listing modems/finding the index number of a modem
mmcli -L

Assume modem index 0.

See the status of a modem:
mmcli -m 0

We need test whether Modem Manager can talk to the Modem.

1)Set logging level to maximum
mmcli -G DEBUG

2)You can check /var/log/messages for the message exchange during command is executed.
mmcli -m 2 --command="E0"

Here is the output :

Yes, dmesg is good. It will dump /var/log/messages.

Your primary port is ttyUSB2 at USB 1-1.3. Modem manager try to use this. But your command tell manager use modem 0 instead of 2.

I don't see any error after you execute mmcli -m 2 --command="E0".

You can use -v option to debug following command.
1)mmcli -m 2 --command="E0"
2)mmcli -m 2 --3gpp-ussd-initiate="*111#" -- I change -m 0 to -m 2.

I am still getting the timeout error.

What should I do next to solve this problem? Should I try
(A) Upgrading ModemManager using deb files from xenial repository or files from any other newer version.
(B) Switching to a ModemManager alternative such as Wader-core or oFono.

Can this be a problem in the modem or service provider (though I don't think this likely)?

You can try upgrade ModemManager. It look like ModemManager has problem. If functionality relative to AT command, it will be failure.

Smile Works!

I was unable to upgrade ModemManger due to dependency problems, because I already had ModemManger 1.0.0-2ubuntu1.1 version, which was the latest for trusty. However, I managed to downgrade ModemManager to version 0.6.0.0.really-0ubuntu7_amd64 and the ussd worked. I think it is probably a problem with ModemManager. What do you say about this?

If your ModemManger isn't able to upgrade, that means that your ModemManger is corrupted. Some module relative to ModemManger doesn't match each other.

I have tried upgrading to ModemManager 1.4.12-1ubuntu1, but after upgrade it refuses to show my Mobile Broadband connections. It only shows Wired, Wireless and other connections, but not Mobile Broadband connections. Also,
Code:
mmcli -m 1 -e
shows a dialog notifying me that it requires the sudo password for unlocking (the dialog shows some problem with System Policy Kit). Even if I provide the password, my my Mobile Broadband connections do not show up. For now, I will be using ModemManager 0.6.
Thank you very much for your help.

Post Found Bug Report

Looks like my problem has been mentioned as a bug here, https://bugs.launchpad.net/ubuntu/+s...i/+bug/1351939.
I am now using ModemManager 1.4.12-1ubuntu1_amd64 in Ubuntu 16.04. I had upgraded to Ubuntu 16.04 Xenial. But the problem still followed. Today I found a patch in the bug report. I applied it and the ussd began working. Regards.
