You can also request your brother, husband, friend to warn the unknown person not to call you again.

  1. I personally use CallApp for this since I already use it for caller ID. Why did this one not make your list?

    1. It did make the list as a matter of fact it’s the last one. At least if I’m reading it right.

  2. NumberGuru is no longer free. There is a “5 day trial” for $1, but after the five days it is like $25 per month, automatically withdrawn from your bank or credit card. I left a message with their customer service a few days ago to cancel my membership, and have yet to receive confirmation.
