Apparatus, and an associated method, for allocating charges that accrue to
download content to a mobile station from a data source, either a
third-party data source or a system-operator data source. An SMS message
is generated at an SMS center that includes an identification of the type
of data source that is to originate the data. A detector at the mobile
station detects the SMS message and the identification of the type of data
source at which the content is to be originated. A table is accessed, and
a calling number associated with the data source is retrieved therefrom. A
terminal management session is thereafter formed utilizing the retrieved
calling number. The calling number forms either a toll number or a
toll-free number and is determinative of to where charges shall be
allocated to download the content.
