But you'll still find the odd landline in homes around the world - but is there something sinister lurking inside them?
It may sound odd, but one man has revealed how he discovered dozens of cockroaches hiding inside a phone in a home in Australia.
The unnamed man was working at a property in Sydney and decided to take a closer look at a dirty and broken phone attached to the wall.
Upon inspection, he was shocked to find dozens of dead cockroaches inside the phone, among the wiring.
He decided to share a video of the bizarre discovery on Facebook where it has been viewed by many.
Alongside the footage he wrote: "I took this video while at work at a property in Sydney and thought maybe I should see what's in there as it looked dirty and was not working."
Several people saw the funny side of the disturbing video, with one viewer joking: "I think your phone has been bugged."
Another commented: "What's the matter... bugs got your tongue?"
A third simply said that it was "disgusting".
