Having a proper connection is a must when you are a first responder, so thank you for reaching out and giving all of the details surrounding the situation. I'd like to gather a bit more info, so we can better diagnose what is going on. Regarding the event, you were at where there was no LTE signal, what was the zip code and cross streets? What exactly happened when you tried to connect to the LTE signal you had during the event (error messages, stalling, etc.)? How were your calls/texts impacted?
