I was mistaken in suggesting the alternative to unlocking at startup was unlocking prompted by individual apps, for two reasons. First, it is indeed present in the network menu. (For that reason, this probably isn't Critical.) And second, we could have an OS-provided unlock prompt whenever an app tries to access SIM functions when the SIM is locked, without the app having any special knowledge of this -- in the same way as the OS prompts when an app wants to access your photos, or (once bug 1275761 is fixed) when an app tries to use the Internet.
Furthermore, that the current error dialog currently directs you to System Settings does not mean that SIM unlock *should* be in System Settings. We could just fix the error dialog -- though directing you to "the network indicator at the top of the screen" is a bit hand-wavy. There's a more mundane reason to access SIM unlocking from System Settings. As long as you can use the phone with the SIM locked, it is weird for System Settings to have a "SIM PIN" screen that lets you turn the SIM PIN on or off altogether, but does not let you simply unlock it. I think it's fine for changing the PIN to require unlocking first, because I think you're unlikely to want to do them consecutively. ** Description changed: Build r91 1. set up a SIM PIN or make sure the inserted SIM has already a set up SIM PIN (reboot device if needed) 2. after reboot, don't unlock 3. navigate to System Settings > Security & Privacy > SIM PIN What you see: A green tick on the toggle next to the SIM PIN and beneath that a "Change PIN..." button What you should see: Some way to unlock the SIM without turning off the SIM PIN. There are three relevant states for a SIM: (A) no SIM PIN set (B) SIM PIN set, SIM locked (C) SIM PIN set, SIM unlocked. If a SIM PIN is set, when you start up the phone you have the choice to unlock it (switch from B to C) or not (stay on B). If you don't unlock it, you can't make or receive calls, send or receive SMS, or use cellular data in any app. And you probably can't predict ahead of time whether you'll want to do any of those things. Currently System Settings only lets you turn the SIM PIN on (A to C) or - off (C to A), not to unlock it. It's not reasonable to expect every app, - that might use cellular data, to provide its own access point for - unlocking the SIM. Therefore, System Settings should let you do this + off (C to A), not to unlock it. System Settings should let you do this too. <https://wiki.ubuntu.com/SecurityAndPrivacySettings#sim-pin>: "Whenever it is locked, at the trailing end should be an 'Unlock…' button..." -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1378883 Title: [SIM PIN] System Settings missing SIM unlock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-ux/+bug/1378883/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
