"Service access denied." from short text code


    I have never been able to use short text codes, i.e. text to ######.

    I always get the response "Service access denied."  This is using

    the default/standard messaging application.  This is not a prepaid

    account.  I have confirmed that the "Block Content Downloads"

    feature is not enabled.  This is on my LG G4 but I have had this

    problem with multiple devices for quite some time.  I have called

    tech support and they are looking into it but so far have not been

    able to resolve the problem.  They walked me through clearing the

    cache and cookies for the Messaging application but that appears

    to have had no effect.  Any thoughts or suggestions?
