Hi. There are several ways for do it. You can use a email-to-sms gateway; there are some portal that are free. But I prefer use a 3g modem connected to the nagios server; you send the sms with the gnokii program, it's easy. The bad thing is you need to pay the 3g. The good thing for use a 3g modem is that if you lose connectivity with the gateway you even send notifications.
