Although I have been a long-time user of Google Voice and Hangouts, I only recently got my first Android tablet (WiFi only, no cellular).

The way the first two interact with the tablet is puzzling and frustrating:

  • As far as I can tell, Hangouts is the tool that Google wants us to use for Google Voice SMS messages.

  • It seems that recently Google removed SMS support from Hangouts except for Google Voice SMS that is still supported, and provided a way to choose what app to use as the main SMS app.

  • With Hangouts installed, everything seems to work, but I get constantly spammed by a Hangouts notification saying that SMS is no longer supported. I have found no way to silence this notification unless I disable all Hangouts notifications, which would make me miss other Hangouts IMs.

  • In the attempt to silence the SMS is no longer supported spam notifications, I tried to install other SMS apps, but since my tablet is WiFi only, I am unable to install them.

  • I only found one SMS app that would install without the cellular hardware (I think called Messenger) and it spammed me with so many advertising notifications that I had to uninstall it, the cure was worse than the illness.

How to silence the Hangouts' "SMS is no longer supported" notification? Otherwise, how to install another SMS app on a WiFi-only tablet that stays nice and silent (which is ideal as I probably will never use it, I would only install it to silence the Hangouts notification)?

I had the same problem and I also wanted to avoid installing an extra app just to get rid of a notification.

The only thing I could think of is Facebook Messenger which I already use. After I downloaded it, the notification disappeared and Messenger was now the default app for SMS.

In case the notification doesn't disappear automatically, go to Settings -> Apps -> (Gear Icon top right) -> Default Apps and you should see 'SMS App'. Just tap on it and choose Messenger (or any other app you want to try). My tablet has Android 6.0.1, so instructions may differ on other versions.

P.S. Firstly, I tried to revoke any SMS permissions to Hangouts so I can clear it from the default app for SMS, but it didn't work.


Unfortunately, this is even one of the sticky notifications which can't be just swiped out of the notification area.

If you, however, swipe it to the right and keep your finger pressed, a gear symbol will appear on the left. When you click this, you can permanently disable this notification. Did the trick for me, at least.

    AFAIK, this will disable all Hangouts' notifications? OP mentioned that he didn't want to disable all though: "I have found no way to silence this notification unless I disable all Hangouts notifications, which would make me miss other Hangouts IMs."
