I've been getting calls from "Unknown" on my iPhone multiple times a day now for a few weeks. Apparently my number has found its way onto a telemarketing/scammers list that blocks its numbers. ATT is of no help. The only thing I've found that might be of use to me is an app called Trapcall: https://www.trapcall.com/ But it costs $5/month. Has anyone had any experience with Trapcall, good or bad? Or is there a better solution for blocking blocked numbers on the iPhone? Thanks.
