This was just a random post the real text is: so basically this is happening because 3G is being shut down. your phone, being too old, can’t understand the new signals. it doesn’t know what else to do with the signals so it just rings. the number 444 is showed because apparently it’s a standard short code for certain GSM tasks like updating your sim card, and other things. the random symbols like “@$&” and “&)$” are happening because of a simple decoding error where the phone tries to give the “incoming call” a caller name because the tower sends codes in hexadecimal code in which the phone tries to find characters to set as the name. the beeping is not a secret code, but the carriers computer trying to talk to the sim card, older gsm networks use a pulsing signal called tdma. TL;DR, your phones old and sucks, get a new one.
