LuserOnFire writes: Google has sent out an email this morning that says in part: "Starting on June 27th, 2015, SMS notifications from Google Calendar will no longer be sent. SMS notifications launched before smartphones were available. Now, in a world with smartphones and notifications, you can get richer, more reliable experience on your mobile device, even offline." You can find the announcement on Google's support pages as well. "Richer" may be accurate, but I'm not sure that "more reliable" describes web-based notifications; that may be why the announcement linked does not apply for Google's "Work, Education and Government customers."
