app for verifying LTE band/radio frequency?

[rory753]

on android, there appears to be an app that can show you what band your on. is there an app like that on WP? or rather W10M?

I hope you will get better views here, so I moved the thread. I can't address Win 10 Mo specifically. I know there are some methods under 8.1, but they are not universal.
