I use the Samsung Messaging app because I felt that VZMessage+ was not secure. I had an issue with an ex being able to read my text and was told by VZM tech support to only use the Samsung app that way texts would not be available on line.
So I happen to check your tech support and it says that texts will only be able to be seen on "text online" if I am using the VZM Message+.
Trying to get to the bottom of this! Can I disable text online for my account?
