I’ve moved your post to create a new conversation. Let’s see if some of our 3.0 users can chime in on some of the differences between our 2.0 and 3.0 phones.
You’ve mentioned you’re not seeing the arc. If you toggle Wi-Fi off and back on, does it not appear? It should be in the notification tray unless you swipe away all your notifications, then it will be swiped away with them, but will come back next time the Wi-Fi state changes. (See: Republic Wireless Arc - Notification Changes)
Now, if you toggle it off and back on, and still don’t see it, there may be a setting to adjust.
As for the Wi-Fi calling setting on the S7 being disabled, I believe that’s because the S7’s innate Wi-Fi calling would conflict with our Wi-Fi calling.
You’ve made several changes - you’ve changed from the Republic Wireless 2.0 app to the Republic Wireless 3.0 app. You’ve moved up several Android versions. And you’ve changed from a Motorola phone to a Samsung phone. I can understand why you’re feeling a bit disoriented!
Let us know if the RW arc re-appears when you toggle Wi-Fi.
