Network changes puts lives in danger

I am furious My husband works armed reaction. Alone in a vehicle suddenly his phone is not picking up Netwirk. 9 at night. How is he supposed to do his work. If he gets fired cause his alarms does not vo through will Cellc give him a job. If somebody gets ****** and ******ed, are you going to give their life back. Who is taking responsibility for this. Tbe poor ladies tried to tell me all they can do is send network settings. He can not stop working to do thiz first. Please feel free to listen to my voice recording of the call. Feedback would be appreciated and not jist an apology. They tried hard enough with that
