Material and methods: This research was a quasi-experimental study which was performed on 106 eligible women (48 participants in the intervention group and 47 participants in the control group). The patients in both groups completed the written consent form and questionnaires at the beginning of the study. In intervention group, the educational content based on HBM was regularly sent via Telegram during one month. After education and three months later, both groups completed questionnaires. Then, the data was analyzed with using SPSS version 22. Results: The findings showed that the two groups at first were similar in demographic characteristics. In the intervention group, the mean difference of the scores before and immediate post training on the knowledge and all of the constructs were significant (P<0.001). Also, the mean difference of the scores before and three months after training on knowledge and all of the constructs (except for perceived barriers) has increased and about the perceived barriers this difference has decreased significantly compared to the score before the training. In the control group, changes in knowledge and other constructs were not significant in during the study. Within the three months after the training, 23 participants (47.9%) in the intervention group, and 4 participants (5.8%) in the control group performed Pap smear which indicates a statistically significant difference (P<0.001). Conclusion: With regard to the individuals’ access to mobile phone, content posted by Telegram on the HBM-based education affects the women’s belief and behavior regarding Pap smear test.
