I have a horrible connection at my home. I get one bar maybe two. I received the update for my S6 and turned on the Wi-Fi calling. What use is it if I cannot use it? I have one bar and my reception of my calls are horrible. I can't hear them and they can't hear me. I have great internet, City of Longmont Fiber with 1 G up and down. I want to be able to use Wi-Fi calling for my calls. But I am stuck using the one bar Verizon signal? Open it up for use all the time please.
