yeah, requesting data must be by a dial-up modem or so, accordingly, u should have a ground service provider to give u the Data sent Service while the data Recived is By satellite,
Almost all Satellites now have Internet Channels (Nilesat, Arabsat, HotBird,.....) in my region.
by the way, if u are downloading Large files and u requested the data, u can disconnect the phone lines and still continue downloading.
u will always Pay, Nothing is free in Today's Life.
