The official site of the Google sms channel says:
Google sms channels is a service that enables channels/groups on SMS. It’s a free service that enables you to get premium content published by Google publishing partners, Google popular products (Google News, Blogger and Google Groups) and websites with RSS/Atom support for free. SMS Channels allows you to create your own channel(s) to publish content that other users can subscribe to. You can also create groups over SMS to communicate with your friends, family, and co-workers.
I have created a channel for this site. I will post a review of it once I get enough input about its working, reliability and hassle free operation. You can try subscribing to it and see it you receive updates from this site.
