"Can you hear me now?" is a question Marc Lefevre takes very seriously. He has walked up to seven miles in one day to ensure the answer to that question is a resounding "yes."
"I get paid to test the network for Verizon," Lefevre said in an interview with CNBC's "Power Lunch."
He does so on foot, as part of the company's "backpacker" testing program.
Equipped with a backpack and a good pair of shoes, Lefevre hits the pavement three weeks every month.
"We have a backpack, it has six phones in it…three are for Verizon three are for the other three major carriers. They will do anything we really tell them to do… make a phone call… upload a file…download a file. It can make a Facebook post a twitter post or Instagram. It can pretty much do anything our customer would do on their device," Lefevre said.
