Can't send SMS when on wifi

I just got a Swisscom Samsung phone.  Why can't I send text messages when I am on wifi only?  I have no cell service in the house and must go outside to send and receive text messages.  

 

my U.S.A. AT&T phone has no problem sending texts through wifi.

I don't see any responses to your query.  Did you resolve it?

 

I'm wondering if your problem is somehow related to the one that I have just posted, where SMS messages sent to my wife's phone come to mind, and vice-versa (but not all the time).  I suspect it is Swisscom's WifiCalling application, but the Swisscom shop didn't know anything about this.
