Entel is a major Chilean telecommunications company, and this tone circulated widely as a mobile ringtone under the EntelPCS name, becoming familiar to Chilean phone users through everyday calls rather than through a song or film release. Its popularity online comes from that shared recognition, especially the joke that it is the sound heard on a bus when someone's phone rings. People now search for it to recreate that moment, use it as a personal ringtone, or add a recognisably Chilean detail to videos and memes.
