Double Curly Loop

Represents a voicemail or callback service, often used to indicate leaving a message or returning a call. Derived from the Japanese symbol for free loop dialing.

Primarily used in contexts related to phone calls, messages, or automated services.

Originally from Japanese mobile carriers to indicate voicemail services, now broadly adopted in digital communication.

Represents continuity, repetition, or an ongoing cycle. Sometimes used as an alternative to the infinity symbol or to indicate something that loops or repeats.

Used metaphorically in contexts describing continuous processes or repeating patterns.

Less common than its primary voicemail meaning, this usage emerged as users creatively reinterpreted the symbol.
