Beyond the cell tower info from networks that's already available, what use would this be, given that location resolution is uselessly broad? Also, how might an "app" be installed on basic "feature" phones?

I do not understand what is being attempted here, or why. Genuinely puzzled and would like to hear suggestions from those who know about these things.

Looks like 'Stalin's dream,'[0] is now someone else's nightmare.
