People who say they get spam calls from using Where's My Cell Phone are paranoid or delusional because I have been using the service a lot two+ years now and have seen no difference in the number of what few bot calls I get. The service is 100% free always and there is a feature where you can voluntarily donate, which I have because I love the service. A tip to users: If you have your cell phone block most calls at night like I do, dial your phone through the service, save the number on your phone, then add the number to your list of calls allowed after hours. I couldn't fund my phone late one night and could not call my phone because of my phone settings.
