Now, if the Swarthmore guy was using his packet 8 E911 service
in Sweeten (or more realistically, Minnesota) would his 911 call be
routed to Swarthmore?
Just to clarify, the friend of mine with Packet8 service lives in
Reno, Nevada and was in "Sweden" (your spellcheck's a bit overactive
;^>).
I always want to spell it Sweeden even though I know a native is a Swede
and not a Sweede.... and, yeah, I knew I spelled it wrong 'cause I
always do, and just trusted spellzilla or whatever to guess it right :-[

Location is indicated, not by some special feature, but simply by what
cell antenna you are using when you make the call. Unlike E911, as it
has been explained, it has nothing to do with your account. I can't see
why it makes any difference, therefore, whether the account is active.
Jon Nelson might be able to give us a definitive answer on this. Jon?
I'd hazard a guess that a cell phone without active service doesn't
have a subscriber entry anywhere which means that the 911 systems
don't have a provider interface from which to get the calling cell.
(Remember that the call comes through just like any other phone
call; the information about calling cell isn't in some carrier
signal, it's based on the CID information--or, actually, probably
the ANI information. I've only a peripheral knowledge of how cell
routing works.)
I don't know enough about it either; just enough to make dangerous
presumptions. But I always envisioned that the routing system knew what
antenna/tower received the initial signal and that the routing was based
on the antenna location without regard to any subscriber info. I would
really be interested in a definitive answer on this, as it greatly
affects the value of those donated phones used for 911.
