please let me know. --Paul

Well this solution is easy to follow and it works

You need account with yahoo or any other mail service provider who
provides the am SMS based alert.
Once sing up with them, you will receive an SMS when important mail arrives.
Here is more information on this issues
http://in.mobile.yahoo.com/edit/mail_learn.html

If your system is UNIX/Linux/BSD based then small script can send
email to this email id. For example when your load of server goes
beyond 5.0, an email sent by script to this email id, which finally
sent an SMS to you.

Thanks for your info about the yahoo sms notification service, but
this will not meet my needs. My script needs to be able to send to any
sms address-- each message might be to a different address. And I need
to have complete control over the entire message.

To find information I finally took help of google.

Hi,

Here is the answer , but a disappointed one :(
There is no free sms service available, because of the following procedure:

Any website wanting to send an sms or a ringtone to a specific addres
has to use a an SMS gateway. The SMS gateway owner charges the website
for the sms messages it sends to gateway. The gateway then sends the
message to the service providers (e.g. Mobilink , AT&T) . The gateway
can do so because it has some business deal for the sms messages and
other services.

For more info about a gateway have a look at popular gateway:
