Changes

The current Debian/KDE image uses NetworkManager to handle WIFI and mobile data connections, but mobile data is not working correctly  when using it under Cosmo. In order to enable mobile data we have to remove NetworkManager and use connman instead. Connman is an alternative connection manager software, which will be used to handle both mobile data and WIFI connection. As connman integration is in KDE is not as seemless as NetworkManager it is suggested to proceed only if you need mobile data under Linux.

Please note that Linux expects the SIM to be inserted in slot 0. ====1 - Install connman====

====Configure APN====The next step is to configure the APN for your specific network operator, which can usually be found online or by contacting your operator[[File:22_46.jpg|center|800x600px|border]]

Usually, this will simply involve setting up the network's access point name through the set-context-property. For example, for the Three UK network we have to setup the access point name "three.co.uk":

Finally, To double check that the information has been set properly you can use the list-contexts command again: <code>/usr/share/ofono/scripts/list-contexts</code> The output of list-contexts should be similar to the output of the screenshot below (see the important bit - AccessPointName = three.co.uk). [[File:22_46.jpg|center|800x600px|border]] In some cases you will have to fill in the username and password information too. For example for EE UK you will have to use "eesecure" as username and "secure" as password. You can do that using the following commands: <code>/usr/share/ofono/scripts/set-context-property 0 username eesecure </code> <code>/usr/share/ofono/scripts/set-context-property 0 password secure </code> Once the APN information is set we need to can activate the connection using the following command:

Your mobile The command should produce no output and yout connection should now be active.  [[File:22_39.jpg|center|800x600px|border]]  You can use the connman system tray application (cstmcmst) to check the status of the network connection: <code>cmst</code> In the Status tab you can see the status of the mobile and WIFI connection. [[File:22_05.jpg|center|800x600px|border]] The screenshot above shows a working mobile connection (State: Online). The Details tab provides additional information as shown in the screenshot below. [[File:22_19.jpg|center|800x600px|border]]   Your settings will be stored and the system will try to re-established the last connection at login. After a reboot, you can also re-enable the connection manually by issuing the activate-context command again: <code>/usr/share/ofono/scripts/activate-context 1</code> Note that you might also be required to send the set-roaming-allowed command if using the device while roaming. ====Running cmst at login====Because cmst will be used to handle both mobile and WIFI connection, it's a good idea to run automatically it at every login. To do that, Go to Menu -> Applications -> Settings -> System Settings. [[File:22_04.jpg|center|800x600px|border]] Inside System Settings, select "Startup and Shutdown", tap on the "Add Program..." button, type "cmst" and tap on the OK button.

You can also run cstm The program will now be executed at startup by..every login.

Note that in some cases ====Troubleshoot====If cmst shows a working namserver connection but you can't browse the Internet, it might be because the DNS has not be been automatically populated automatically. In this case you can set one using the following command:
