Except when they, you know, can actually play a role. Like when some feature gets enabled with them like VoLTE support or WiFi calling support or perhaps something related to voicemail. Recently it seems like T-Mobile was having some issues related to IPv6 support where carrier settings played a role. And earlier on in iOS 10 there were some issues with a few carriers related to different things that also needed carrier updates to get resolved. For all those that were affected it sure sounds like carrier settings discussions were "literally non essential".I freaking hate carrier version discussions they are literally the most non essential posts ever. 0 value
