I’ve been getting over a dozen rando calls a day. Basically have had to put my phone on permanent DnD and then allow my contacts to bypass. No more!
This app is successfully blocking those annoying virtual numbers via STIR attestation.
Unfortunately it doesn’t fully block SMS. It blocks the notifications, but they still appear in your SMS app needing to be manually deleted.
Been running this one since finding out about it a few months back and it’s made such a difference blocking stuff that nothing else is catching for some reason.
They were still leaving me voicemails annoyingly, but I found out that when this app blocks numbers it does so by treating it like I’m busy on another call. So now I just redirect all busy calls to a voicemail number that doesn’t exist, and poof, no more voicemails either!
