Apparently, the app has gone live today. However, I don't see it when I search in Galaxy Apps or the Google Play store.
It isn't in either of those.
Who is your carrier?
S6 active is ATT. I'm guessing that until we get the 5.1.1 (whenever that is) it will be in the update
Not sure if it will have Samsung Pay. It seems Samsung has said no to a couple of people. I think the Active supports MST, but I can't find anything definitive concerning this though.
Not sure what MST is. Same phone as the GS6 other than the fingerprint scanner
That is Magnetic Secure Transmission. That is the thing that allows Android Pay to use something other than NFC and why any terminal that you swipe your card, will take Samsung Pay.
I emailed samsung on this yesterday and they replied that as of now the samsung pay app is not compatible with the s6 active. I tied to load the apk and framework apk onto my s6 active but it would not install.
