Doesn't always work in older mobile homes or automobiles! Wish could block solicitors us using someone else's number! Update Now all of a sudden all incoming calls ring once then goes to voice mail or text messages I've Uninstalled the app and reinstalled still not working, looking at ratings I see I'm not the only one with this problem! I don't mind the advertisement if that is what it takes to get something free! So what can I do to help fix this problem sooner than later?!
