This study explores the experiences of clients participating in non-face-to-face telephone counseling. Using a phenomenological qualitative research design, in-depth interviews were conducted with six female clients in their twenties who had engaged in telephone counseling for at least one year. The collected data were analyzed to identify the essential meanings of clients’ experiences throughout the counseling process. The findings revealed three overarching domains—experiences before telephone counseling, experiences during telephone counseling, and experiences after telephone counseling—along with 22 categories. The participants perceived telephone counseling as relatively effective compared to face-to-face counseling and evaluated its convenience and accessibility positively. In particular, psychological comfort, reduced emotional burden, and increased openness were identified as salient features of telephone counseling experiences. Based on these findings, this study discusses the essential nature of clients’ experiences in non-face-to-face telephone counseling and suggests practical and theoretical implications for enhancing telephone counseling practice. The limitations of the study and directions for future research are also presented.
