Why does my phone keep going into SOS mode and dropping calls. This has been happening for months now on all our phones. We have had verizon for years and no issues, then the last few months. Sos mode all the time. I am tired of having to go into airplane mode and out or turn my phone on and off. I do not want to reset my phone and lose all my data because of this issue. Why is this not fixed and how are you going to resolve our issue?
