Comment 25 for bug 1373463

Randall, that screenshot is not relevant to this bug report. It is of Android's Settings app -- but the equivalent screen in Ubuntu's System Settings already has a switch for cellular data. On the Android 5.0 phone I just tested, you can get to that screen by tapping the Cellular icon in Android's quick settings panel -- but you can get to the equivalent screen in Ubuntu by tapping "Cellular Settings" in the network menu, so there's no practical difference there, either. (Or if there is, it's that System Settings takes too long to open, which would be a problem for dozens of access points, not just this one.)

Android's quick settings panel does not have a toggle for cellular data. <https://support.google.com/nexus/answer/6111329> Neither does iOS's Control Center. <https://support.apple.com/en-us/HT202769> And neither does Ubuntu's indicator menus. I emphasize this because Jelmer's and Sebastien's mentions of Android might have given the impression that Android has what people are asking for here, when it does not. The only platform that does, that I know of, is Windows 10 Mobile. <http://windows.microsoft.com/en-us/windows-10/getstarted-notifications-mobile>

Turning off cellular data would not stop you from getting notifications through wi-fi, or from on-device events such as reminders; if you want to pause notifications you need something like a Do Not Disturb mode. <https://goo.gl/yoiVKM> Nor is it a viable way to ensure that you continue getting phone calls, since the proportion of phone calls that use PSTN is only going to decline, as is already happening with the proportion of messages that use SMS. <https://goo.gl/vkJldD> And for limiting data use to a quota, much more effective would be to tell you how much you've used so far (bug 1287267), and to provide the option to cut it off automatically before you reach the limit (bug 1292930).
