One of the most iconic "phone" moments occurs when Arnav pretends to be on a call just to avoid talking to her, leading to classic comedic tension.
She often uses her phone during her "crisis jalebi-making" sessions or to call Arnav to annoy him with her constant questions.
Unlike Arnav Singh Raizada, who always uses high-end smartphones (like the iPhone models of that era), Khushi’s phone is simple and bright, reflecting her middle-class background and bubbly personality.
In the kidnapping arc, the phone becomes a critical tool when Arnav manages to get a hold of a kidnapper's phone to contact Khushi, though she initially struggles to hear him.
