Your phone app does not work correctly now. It acts like it wants to call then drops the attempt and disconnects. I have un installed and updated and still no help. My husband has Consumer Cellular service and I have SafeLink service and both are having same issues. /I have good bar service 4-5. I sometimes believe it's with the dialer part of app. There is no dial tone just says it's calling them drops the attempt shutting down the dialer.
