Comment 9 for bug 1373463

One option would be to have just a switch in the indicator, called "Internet connection" and which can be turned on or off, replacing the current "Wi-fi" option. When enabled, the list of wifi access points would appear below it, and also the mobile connections for the two sims, if available (if one of the SIMs is in roaming, and in System Settings the user has chosen not to use mobile data in roaming, that SIM connection should not appear).

Then, in the System Settings, there could be more options, such as whether to prefer wi-fi over a mobile connection and switch to it whenever available.
