I had a Comcast tech out here a couple weeks ago. I started talking to him as he entered and he looked at me and showed me his ID and started talking, and I realized he was deaf. Imagine that! we switched over to sign language and it was much easier.
Anyway, he had a device that was connected to his supervisors and coworkers that worked back in the office and data rooms or whatever. But the device was also his diagnostic tool and how he changed the numbers and stuff. This all-in-one device. Anyway, instead of calling his coworkers, whom he had to coordinate with, they just sent texts back and forth using his device. It made that part of the job a breeze for him. I thought back to when I was working at an apartment complex and had to use a walkie talkie, and I could never understand anything on it. I really wish it would have occurred to me to use texts back then. But I didn't even carry a cellphone with me, so oh well.
