rayin Report post Posted April 30, 2018 Most already know what I learned when I visited a Verizon store in search of a signal booster. Many smart phones have an advanced calling feature which when turned on allows the phone to search for a WiFi signal, connect to it, then use that WiFi to send/receive when you do not have cellular service. It even works when the WiFi signal is protected by a password, leastways my phone does, and my buddies phone does. Share this post Link to post Share on other sites
