Hi all... I have an S7 Edge and love it. However, over the last month or so I have been getting the popup message "Mobile data not available while on this call" when Im on a call. I have advanced calling activated through Verizon and turned on. When I contacted customer support they said that there had to be a 4g connection in order for data to work while on a call. I live in LA so there is 4G everywhere and tbh....when I had my LG G2 I never had this issue. Any insight that would help me would be great! Thanks!
