Until the late 1970s, it was -in essence- illegal to physically own your phone. All hardware was provided, and possessed, by the respective phone company (there was but a single, major one back then). Everyone was charged a "rental fee" on their monthly bill for their standard, wall or "Princess" model.
The Princess Phone, marketed to the ladies, was introduced in 1959. On the left is the standard, rotary-dialing model. A more modern version, utilizing touch-tone telephony, is seen on the right.

The phone you would have rented at your local shopping mall "Ma Bell" store would have utilized analogue, "rotary-dialing". "Touch Tone" telephony did not appear until 1963, and did not become commonplace until the mid-1970s. Moreover, answering machines didn't come into prominence until the late 1970s.
Oh yes, no one had a cellular phone until the mid-1980s, and these were rather large, clunky things...nothing like the super-miniaturized models of today.
First off, back in the vacuum tube-based days of electronics, tvs, radios and record players did not come on instantly after the "on" button was clicked. There would be a pause of a minute or two, while the set "warmed up".
The "instant on" feature was something to "ooo" and "ahh" over, when the first "solid-state" (transistorized) televisions became common in the early 1970s. By the mid-1970s, tube sets, and vacuum tube electronics in general, had become a thing of the past.
