Comment 7 for bug 1607291

I've been looking at screenshots of dual-SIM Android phones (bq Aquaris 4.5, bq Aquaris X5, Oneplus 3…) and find none that had an empty SIM icons in the panel. Pictures on their respective websites show two (working) network icons, to emphasize the fact that those phones are capable of doing this. But if you look at reviews, hands-on etc, sometimes there is no SIM inserted (you only see the WiFi icon) and most of the time there's only one. And I could not find any picture with an empty SIM in the top panel.
Maybe someone who owns such a phone could confirm?
If I'm not mistaken, then how could Android not meet carrier certification requirements?
And how could carriers require an operating system to display useless information like that? Dual-SIM is just a feature that's becoming fairly standard, but it doesn't mean you have to use it. It would be just as silly to always display a Bluetooth icon when you just don't use it, a WiFi icon so that you are reminded that your phone is capable of Wifi, an icon for your GPU saying "hey, you're not using me right now!", etc. The top panel is small and should not be cluttered.
