When you dial any 10 digit number and press call button.
Your phone sends your sim card id number with an authentication key (something like a password) that is in your sim card to the operator like Airtel, Vodafone, Jio, Aircel (sorry Aircel is no more with us)
Now after receiving your sim card id number and your authentication key, it generates a random number (assume 12345) and uses authentication key to generate a response number (assume 88888) at the same time.
After that the random number generated by your operator (12345) sent back to your phone, now after receiving that random number, your authentication key will generate a response number (88888).
If both random number match, your provider will recognize that it’s you and after that, it connects to whom you want to call.
If your number doesn’t match you can talk that’s why sometimes your call doesn’t connect and it keep sounds like beep beep beep.
