Pantech sold its SKY phones under the VEGA name in South Korea during the early smartphone era, and models from 2010 to 2016 shared a family of system alerts including this Bell 2 variant. Unlike generic beeps, the tone was tied to everyday phone use, so recordings later circulated on soundboards alongside other notification clips and the classic ding sound effect. Its survival comes from familiarity rather than novelty, as the short bell still reads instantly as a warning that a device needs charging.
