OT - NO (Non-Operational) Question

[Joe Blanchard <jbfixurpc () gmail com>]

Happy holidays to all.

Quick question with regard "Text/SMS" messaging. I know this is not really
the place to ask, so forgive me for bending your eyes. It appears there's
really no easy way to determine the origin of a text sent to a cell, at
least as far as I can see without involving the provider(611)  Any quick
links/ideas as to where to research this?
Perhaps something obvious I missing?

And yes, I tried, lmgtfy.com (:

Thanks in advance, and happy holidays/Xmas/New years to all,
