Apple Had a Better Idea:

24. Hmm. The app my wife uses is a streaming app,

but the phone is on our wi-fi network, so it doesn't involve any cell data. She listens to it at night, in bed.

We're on an unlimited data plan with Verizon. It's a family plan so, her sisters also are on the same plan.

We have five or six cell-enabled devices. Maybe more. I don't keep track of her devices at all. My wife reviews websites and online software mobile apps, so she has to have a range of devices available for testing. She has one of the latest iPhones, just for app testing. It's all a business expense for her. My cell phone is on the plan, too, but gets less use than any of her devices. It replaced a cell-enabled dongle on an old notebook computer. We hadn't used it for a couple of years, but there it was on her list of devices. So, I swapped in my cell phone on that number.

I'm her tech support person, so I've had to learn all of her devices so I can fix any problems that come up. The latest one was echoing on one of her phones during phone convos. She couldn't seem to solve it, despite searching for a fix online. I fixed it for her, by shutting off the wi-fi connection. That phone is gone now, though, so problem solved.
