Can you still use rotary dial phones?
Likewise, can you still make calls on a rotary phone?
Absolutely. The ONLY requirement is DIAL TONE. Touch Tone (DTMF) is an invention added to phones but the Original Phones used a crank system that evolved to rotary.
Similarly, when did rotary phones stop being used?
Early models even used the same rotary dial signaling on the PABX but used buttons as the input. This was first introduced in the early 1960s and the 1962 World's Fair under the trade name "Touch-Tone." By the 1980s most rotary phones were being phased out in favor of this new upstart.
Across the United States, 2 million of the nation's 120 million households still lease phones. Probably some of them are rotary holdovers, but no one knows how many, according to Lucent Technologies Inc. So rotary users are a minority, but they're still out there dialing.
