WebCam Monitor can send email when an alert is triggered.  Most mobile phone companies offer an email-to-SMS service.  You can send email to a specific address and have it delivered to your phone as a text message.  For instance, the Spanish phone company Movistar uses ####@correo.movistar.net.  Substitute your mobile number for "####" and your WebCam Monitor alerts will be delivered to your Movistar phone.  There is no charge for this service beyond the normal cost of receiving a text message.
