n the last few years, SMS (Short Message Service) has made a big impact on the way we communicate (or at least the youngsters). Instead of communicating over the phone using voice, more and more people are turning to using SMS for messaging. One of the popular uses of SMS is for voting. For example, you can vote for your favorite contestant on the television program "American Idol" by simply sending an SMS message to a particular phone number. This is then automatically tabulated into a final vote count for each participant. Traditionally, to implement such a system, you needed to buy an expensive SMS gateway, which is overkill for a small project with limited budget.
In this article, I will show you how you can use a Windows Mobile 5.0 Pocket PC device as an SMS gateway for voting purposes. Figure 1 shows the architecture of the example system you will build.
