Comment 1 for bug 1657589

FYI, I made a branch for this at one point:

The "Must enable on device" comment on Republic Wireless was because it wouldn't work when I first set it up for MVLC without people turning on the functionality. I haven't checked to see if that is still the case. I also added Google Fi to the list at some point, apparently.
