Alerts were going off all around me today. Tornado warnings and watches. My phone said absolutely nothing. Called Verizon and eventually was disconnected; the rep didn't try to call me back. A tornado touched down not too far from my home. Called Verizon again and was on hold for 20 minutes. Decided to try to figure it out myself. Everything was set to alert me, but when I tried to hear the sound that would be emitted in the event of an alarm and there was silence. I turned the location setting to high accuracy. When I checked for the sound after that change, I finally heard the sound and the text to speech. I hope this helps you. Now I can go to sleep.
