Scam Calls > 50%
50 percent of calls will be made by scammers in 2019.
This is a prediction (and likely an easy bet) from a company that provides data and phone call solutions to mobile carriers, First Orion.
The largest increase will probably be from "neighbor spoofing." This is where a scammer will spoof the calling number with either YOUR number or one with the same area code and at least first three digits like yours.
