Not Getting Messages

Configured the said SMS Alert Thing in a proper manner but still unable to receive any kind of alert messages.

Even Nagios Linux Shell Command Execution Shows That SMS has been sent but I couldn’t see it.

./notify_worldtext_sms.pl -i 33333 -k -d +919879597301 -t Hello From Nagios –sim

The OUTPUT is “Message sent succesfully to +919879597301
“, but I don’t get it.

AFAIK, if CLI doesn’t work, how would the nagios configuraiton works ?
