Is it possible to enable or force additional carrier settings that seem to be hidden on some devices / networks? I remember reading that certain mobile providers disable these settings and I'm unsure why, but probably because they're trying to phase out the older technologies. I believe cR droid has this option.
What I've noticed, is that if I turn off my SIM card and then re-enable it, I get a few additional settings I can toggle before they disappear (preferred network type and which network I want to use). My carrier settings version also seems to revert to something older, but when I turn the SIM card back on it updates itself, and then I lose some settings.
I've included a screenshot of the settings that appear briefly when turning on the SIM before going away after the system enables whatever it does to hide these.
