Dude, get her a free-roaming access mobile phone, make it 2
phones. One phone hide somewhere in her socks or sth. In case she
gets kidnapped, she can use it.
Then buy her a panic button alarm. The kind which lets out a
screeching alarm when she is in danger.
Find out the number of the SG embassay in that country and label
the tel number in laminated sheets. Multiple copies of it will be
good.
It will be best if you can accompany her to the trip. Cz frankly as
much as she may want to admit her fear, she will not give up the
trip because that would be so embarassing for her. You need to
create excuses that convinces her to give up travelling but yet
does not dent her ego. How about something like, "Hey you will need
to pay a bomb in airport taxes, fuel surcharge and safe deposits in
this volatile time when fuel price is unstable. Fly another
time?"
