How to get rid of "SMS is no longer supported" notification My 5.1.1 tablet has an icon in the notification area. It looks like a Google Hangouts icon.  But the drop-down reads "SMS is no longer supported. To read and send SMS messages, please download Android Messenger".

Well, this tablet is wifi only, so I could never send SMS messages anyway (except faking it with Google Voice).  The annoying thing is, there is apparently no way to get rid of this notification icon.  I even tried installing Android Messages to see if that helped, but it didn't.

How can I get rid of this annoying and useless (to me) notification icon?
Have you tried turning off SMS option inside of Hangouts?
