More people are ditching their landline phones.
A new government report finds 4 in 10 American households dropped their old landlines, and now only use cell phones.
That's twice the rate from just five years ago.
Experts think people are still holding on their landline phones because it's part of a package deal with cable and internet providers or, it's tied to another service like a security system.
The Centers For Disease Control study also found younger people rely on cell phones more.
Nearly two thirds of people in their late 20's used cell phone exclusively, while only 14% of people 65 and older cut the cords on their landlines.
