@disherm, this feature can be country or operator dependant so it means that not all S9 / S9+ receive this feature. Some variants may receive it later and other may not receive it at all. What is your phone software version and country variant? To check it please go to Settings > Phone - information > Information about software and provide data visible in green marked areas.
Hi I have the galaxy A40 and a s5e galaxy tab which support the feature,although at first all I got was just messaging but it now fully makes and receives calls,I am in north east England on the three network. Hope this is of interest.
As of today I believe that this function is now released for the Galaxy note 8 as I just updated my phone and am able to access this feature, I am not sure what I am supposed to do in order to use my computer to now send SMS texts while I am at work since I am not able to use my phone during work.
@NickToNock, if you want to send messages from your computer you should use for example Your phone app from Microsoft. Call & Message Continuity works only across supported Samsung devices. You have Note8 which is main device and you need additional device like tablet or watch. Below please find supported devices.
Main device (phone):
Oh I see, well I actually have a chromebook and thought I could find an app or something that would allow me to use it via PC, but since I cant at this time Ill just not use the feature until then.
