Google SMS Labs now enables me to create channel and update anyone or a particular group of members (by invitation) with SMS alerts. I created a Channel called SHALINJAIN. So, whenever I update my blog you would get a SMS with brief description about the post. It is almost realtime. The invitation process is really simple. If you already have a GMAIL or Google Account just clicking one button would do the needful.

Give it a shot.
