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?
For regular cellular numbers, the Wireless Amber Alert site is popular
amongst MVNO (e.g. prepaid) users to find out so they can use the
email-to-text gateways:
(You don't actually sign up, just enter the number and then it will tell you
the carrier.)
For landlines/VoIP/etc. Google should be able to tell you at least the
city/state. Though it's rare that you will get a text from a landline, it is
possible.
I could be wrong, but I think the actual question was "is it realistic
to assume a text to a cellphone came from the number it *says* it came
from?" and I think the answer is "no, there are a few ways to spoof it".
Received SMS messages are probably not evidentiary, absent a report from
the receiving carrier of the message traffic log involved, which would
itself be hearsay unless someone testified about it.
