I had tried a 3rd party hot-spot on my old phone. It kept knocking it off. I'd get about 30 seconds of hot spot use, then it would konk out, and I'd have to reboot the phone. But, it was just enough to download something like a Strava Route.
On the new phone, however, the hot spot seems to be stable. Unfortunately, I think I allowed the phone company to change my unlimited networking to something like 2 GB a month, so I have to play the hotspot data pretty tight.
Nonetheless, it was handy last weekend, and I'll probably make more use of it in the future.
I'm still one of the holdouts of actually having a telephone.
If I ever got my cell phone stable enough, I'd be quick to shut down the phone. Perhaps I should evaluate that again.
