On the off chance your cell phone is of the decidedly dumb variety, Mountain View's engineers have worked out an alternative solution to keep your Google + circles intersecting. Initially available only for the U.S. and Indian markets at the time of the social service's launch, the search giant's expanding the reach of its SMS feature to over 41 additional countries, giving users the option to post updates, as well as receive and reply to notifications via text. The feature isn't standard, so if you want to opt-in, you'll have to enable it in the settings menu first, provided your carrier is supported. Luddites that like to have their online cake and eat it too, might want to make sure they're packing an appropriately capacious mobile plan before those thumbs get to banging away. Of course, the rest of you modernists are more than welcome to join the party, but why would you?
