I would like a more detailed explanation of how the SMS Call Filter works. For instance, what is the difference between blocking “All Hidden Numbers”, and “All Unknown Numbers”? I want to block incoming calls that show “Private Number” on the caller ID, but not sure which is the correct one?
Also, when they are blocked, what happens? Do they go to voice mail, does it hang up on them, etc? I would like it to go to voice mail, but I don’t see any options for this.
