That's not the only issue.  Recently somebody called 112 (the
international GSM emergency number) from the local golf course in
Mt. Barker SA, saying he had had a heart attack.  He specified exactly
where he was in the golf course, but help didn't come.  It *did* go
looking for a golf course in Mt. Barker WA, about 2000 miles away.
The emergency centre didn't know about Mt. Barker SA, and the caller
didn't realise they weren't local.  One of the disadvantages of having
a separate prefix for mobile phones (in Australia, they all use area
code 4).
