Add fiber and wireless then you may have competition.

I would say separate the infrastructure from the service. Don't allow a service provider to own the delivery medium. We have competition for electric service because one companies maintains the grid, and the other companies with power plants feed power onto it. The grid owner reads all the meters, and the power plant companies bill according to the meter. Phone service, cable TV, internet, all these should be done like electricity. One grid who sells access to the service provider, and the service provider bills the consumer.
