I have configured sms with gammu-smsd. gammu-smsd configuration has been given below:

#vi /etc/gammu-smsdrc

 # Configuration file for Gammu SMS Daemon

 # Gammu library configuration, see gammurc(5)
[gammu]
 # Please configure this!
port = /dev/ttyACM0
connection = bluephonet
 # Debugging
logformat = textall

 # SMSD configuration, see gammu-smsdrc(5)
[smsd]
service = files
 #logfile = syslog
logfile = /var/log/gammu-smsd

 # Increase for debugging information
debuglevel = 0

 # Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/

Answer

Convert nagios.log timestamp to a human-readable format:

perl -pe 's/(\d+)/localtime($1)/e' nagios.log 

[Wed Aug 29 16:58:30 2012] SERVICE ALERT: localhost;SSH;CRITICAL;HARD;4;Connection refused
[Wed Aug 29 16:58:30 2012] SERVICE NOTIFICATION: localhost;localhost;SSH;CRITICAL;notify-service-by-email;Connection refused
[Wed Aug 29 16:58:38 2012] SERVICE NOTIFICATION: localhost;localhost;SSH;CRITICAL;notify-service-by-sms;Connection refused

You can see that it send an email notification immediately and takes only… 8 seconds to send a SMS. The delay (as @John Gardeniers pointed out) is in your SMS system, not Nagios.
