I am getting an sms error. It says Cause Code: 65535 Error Class: 3. Also when I get this it also will not let a call go through or me to receive a call. When I try to make a call it says, "Call origination attempts fails due to an immediate signal loss (signal fade or service available)" I have full bars of service and there is no service loss. What does this mean and how can I resolve this issue? I have screen shots to show.
