Has anyone successfully used Wi-Fi calling on the Astound?
When I turned on Wi-Fi calling and connected to Wi-Fi, I saw a small circle next to the signal bar (replacing the word "3G"). Can I assume that, if I see the small circle, the phone is ready for Wi-Fi calling?
Yes, the little red circle means you are using uma. Mine works OK, but the sound quality is hit or miss. Sometimes it is fine and sometimes the call is very "gravel sounding". I usually check my voice mail to make sure it is working when I am counting on wifi calling to work.
