Want to swap your Verizon copper for FiOS? Just call to complain.

If Verizon has to visit a copper line customer more than twice to repair the line, the communications company thinks it’s a better idea to just switch the customer over to fiber.

Verizon has sold off much of its landline and DSL business in the last few years, but it still has about 9.9 million copper voice and 3.9 million DSL customers on the books. And while its FiOS expansion isn’t expected to move forward rapidly anymore, Verizon CFO Fran Shammo said the company would embark on a strategic initiative to replace problem copper lines with FiOS for lines that experience “chronic problems.” Shammo said: “So what you’re going to see this year is a very strategic initiative, that we go out and we look at areas where there are chronic copper problems and we start to transform them onto our FiOS network. And the math would say if there is a chronic problem that we have to visit more than two times a year, the actual financial benefit of us transforming that to FiOS pays for itself within that year.”
