Popup SIM PIN unlock interface after power on device 4. cancel this dialog 5. Go to phone app to make a call It is not obvious that the next step should be to drag down the indicator and use the unlock button. the phone and messaging apps should have a shorthand button clearly visible to unlock the relevant SIM so that the user does not have to "know" to go to the indicator-network first to be able to make phonecalls or send SMS To manage notifications about this bug go to: https://bugs.launchpad.net/indicator-network/+bug/1362150/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
