The motivation of a company or industry is to make money, greed comes first before helping people. That is true with your mobile communications company, as it is for any company. They would do whatever it takes to make profit, no mater who it harms and those without money, without funds to pay for the basic services of food, shelter, and medicine are screwed. The purpose of government is to serve the needs of those who are governed and protect those citizens from ravages of greed and corruption that private industry fosters. Not so much for telecommunications, but the medical and insurance industries are notorious of screwing people over. Without government intervening on our behalf the common person on the street would live in misery while the rich will live in luxury moreso than they do now.
