As SMS becomes the defacto way of communicating via mobile devices, it's no surprise that many services have come out that put the power of SMS in developers hands.

Zeep Mobile is the latest service providing developers an easy way to send and receive SMS from their own applications.

TextMarks and MsgMe are two other such services that have been out for a while.

So what does this mean for those wishing to have their applications interact with SMS? It means you're dependent on a service that, although free, has some drawbacks:

• The SMS short code is not your own unique code.
• Unless there's a paid version, there will be ads in your SMS messages, further limiting the available character space.
• Users have to become accustomed to prepending their updates with your unique keyword, ie: yourapp myupdate.

Still, it's nice knowing that SMS interaction won't cost you the two grand per month to own a unique short code.
