@tmo_Chris,I'm having the same issue with my S9 where SMSs Fail To Send... until I disable my wifi connection. Then they send fine.Seems like a lot to submit that information you requested... I've been waiting for someone else to help you all with research-- I've been checking back for a solution....Nonetheless, if this still has not been solved, I'll go ahead and "bite the bullet" and collect/send that data.
