Introduction

Being able to send SMS messages is a major part of any project that involves phone work. I use it to send reminders, hold chats, and a variety of other tasks related to the projects being used.

In this chapter, we'll send messages from a website, track the received messages, send bulk messages, track orders, host a group chat, and send SMS messages when we receive a phone call.

We're also going to build a simple website monitor that will check a group of websites every five minutes and send you a text if the site is down. By the end of this chapter, there won't be much that you won't be able to do with SMS and it will make for a fun experience to enhance your web apps.
