For my own edification, would you mind linking these posts you're referencing? The only comments on the reddit thread that I can find that say anything like that admit they're speculating, as opposed to the actual post which says the only thing that cell reception has to do with this is that the remote team can't access it remotely without cell reception (which is a no-brainer).

This might be a more contrived example, but this is kind of like trying too many times to unlock your tablet (made from platinum) and tech support can't unlock it when you call them because your router died and your wifi is down.
