This year's Super Bowl, which will take place at Levi's Stadium in Santa Clara, California, has taken over its neighboring big city, San Francisco, as well. As the game approaches this Sunday, February 7, tons of people are flowing into the city. To keep up with the influx, US carriers like Verizon, AT&T, T-Mobile and Sprint are adding more cell towers to increase their network capacity.
