When communicating with friends or relatives, you do not need to worry about the phone mode, but if you call the support service, then, most likely, the operator's voice on the answering machine will ask you to switch the phone to tone mode. Then you can use numbers to give the answering machine commands.

Step 1
In total, stationary telephones have two modes of operation: pulse and tone. In Russia, landline telephones use pulse mode by default, while payphones and mobile devices use tone mode. First of all, it's worth finding out if the phone is already in tone mode. Suddenly, the telephone exchange assumes exactly the tone mode of operation by default. To determine this, try dialing any number. In pulse mode, when dialing a number in the handset, you can hear clicks, and in tone mode, the phone emits short tones.
Step 2
Almost all modern phones change mode if you just press the star - the button that says *. If you pressed this button, but the mode did not change, look for the P and T buttons on the phone body. P stands for pulse mode, and T stands for tone. You can switch the phone to tone mode by pressing the T button. If these buttons are not present, then you will have to find instructions, since the phone model has a very special way of switching between modes.
