For those who didn't know what 444 is, it is not phenomenon call, it's just a phantom call that happens when your mobile device only support with 2G/3G, which has already end support to this day. If your phone displays weird text symbols (like @$& or %%#) during or after the call, it is doing the exact same thing with text. The cell tower is sending numerical hexadecimal instructions to the phone's computer. Because the phone thinks it's a phone call, it tries to read that computer code as a "Caller Name," spitting out random characters from the ASCII text table. Older networks use a pulsing signal delivery method called TDMA (Time-Division Multiple Access). When the phone forces the glitchy "444 call" open, it forces the hardware speaker to play the raw audio frequency of the cell tower trying to send an automated, encrypted data packet to your SIM card. There is no hidden message or Morse code inside the call. Because it sounds exactly like rhythmic dots and dashes, many people online have tried to decode it, but it translates to complete gibberish. The audio is actually a sound artifact of computer data. It sounds spooky, but it is literally just the acoustic sound of a cell tower and an old phone modem failing to speak the same language.
Note: This video was ALL fake Morse code is just some giberish I type, nothing to decode here Credits to all
