Please note that Linux expects the SIM to be inserted in slot 0.
====1 - Install connman====
On your Cosmo, open a terminal (Menu -> Applications -> System -> Terminal)
<code>sudo apt install connman cmst mobile-broadband-provider-info ofono-scripts</code><code></code><br /><code>sudo apt remove network-manager plasma-nm</code><br /><code>sudo reboot</code>
====2 - Enable Roaming====
Roaming needs to be explicitly enabled beforehand if needed. To enable roaming type this command in a terminal:
<code>/usr/share/ofono/scripts/set-roaming-allowed</code>
====3 - Configure APN====The next step is to configure the APN for your specific network operator. For some operator the APN details might be already populated correctly. For some others operators you will have to retrieve the APN details, which can usually be they are found online or by contacting your operator.
UsuallyTo check what APN details are stored, this will simply involve setting up use the network's access point name through list-contexts command and look for the set-contextinformation below /ril_0/context1: <code>/usr/share/ofono/scripts/list-propertycontexts</code> [[File:22_46. jpg|center|800x600px|border]] For example, for the Three UK network we have to setup the access point name "three.co.uk":
<code> /usr/share/ofono/scripts/set-context-property 0 AccessPointName three.co.uk</code>
<code>/usr/share/ofono/scripts/set-context-property 0 AccessPointName online</code>
To double check that the information has been set properly you can use the list-contexts commandagain:
<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):.

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:
[[File:22_46.jpg|center|800x600px|border]]<code>/usr/share/ofono/scripts/set-context-property 0 username eesecure </code>
<code>/usr/share/ofono/scripts/set-context-property 0 password secure </code>
Finally, Once the APN information is set we need to can activate the connection using the following command:
<code>/usr/share/ofono/scripts/activate-context 1</code>
The Details tab provides additional information as shown in the screenshot below.

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.
[[File:22_58.jpg|center|800x600px|border]]
You can also run cstm The program will now be executed at startup by..every login.

What about SIM1/SIM2?====Known bugs and limitations====* Linux mobile data is still experimental at this stage, and not all features are enabled.* Thetering functionality is not currently working.* SIM must be insterted in slot 0, eSIM chipset is not currently working in Linux.* Powering OFF and ON the mobile chipset using cmst does not always work as expected - in this case a reboot will fix the issue.* CoDi external screen not yet working in Linux
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:
<code>sudo echo "nameserver 8.8.8.8" > /etc/resolv.conf</code>
