I'm in the process of prototyping a monitoring device. When certain conditions are met, I need to send a SMS or comparable type of message to a mobile phone. My issue is that I don't really have any ideas on how to do that. I've tried to find answers in other places, but I haven't been able to find what I need. Can someone tell me what kind of methods are available for accomplishing this goal? Thank you. I'm not sure if this is the right section for this question. If it's not, I apologize and I will remove it and post it in the appropriate section.
