Well, it seems clear that the nagios part is working correctly. You _do_
get the email that is the second half of your notification script and it
does appear to be passing the correct information to your send_sms
script as it gets logged at the end. That would imply that the failure
is somewhere in your for...done loop. The loop itself seems to be
unnecessary as there is only one phone number but other than that it's
pretty generic leaving the echo to gnokii as the next most likely
culprit.

I would try two things... enclose the argument to echo in quotes --

echo "$1" | /usr/local/bin/gnokii --sendsms $x

and/or see if gnokii is spitting out anything interesting --

echo $1 | /usr/local/bin/gnokii --sendsms $x >/tmp/gnokii.log 2>&1
