I've experienced very limited signal strength since moving to Florida 2 and a half years ago. I have been patiently waiting for the ability to use Wi-Fi for calls but that has been a long time coming. I am frustrated when attempting to talk with someone from inside my home; they just don't understand the garble. I have another year under contract but I find myself looking at different carriers that will solve my problem. I know AT&T has Wi-Fi calling. Will Verizon offer the same soon or is that vaporware?
