Background and Aims: Pregnancy has its own side effects and thus it is vital for women to be informed about the risk symptoms. The present study has been designed to investigate the effectiveness of mobile based education regarding signs of pregnancy risks. Materials and Methods: An experimental intervention study was conducted on 120 pregnant mothers by cluster sampling method. The study population was then randomly divided into control and intervention groups. Twenty one educational text messages regarding risk symptoms and common complaints were sent to the intervention group on a daily basis. During two weeks thereafter, the important points were resent as remembering message. A questionnaire was used for collecting data. For data analysis, SPSS software version 22 was used for statistical analysis, using variance analysis, Friedman, and Cochrane. The significance level was considered as 0.05. Results: In this study, the knowledge score of both groups improved after intervention, but the changes observed in the intervention group were not statistically significant. The behavioral pattern was better in the two groups after the intervention, but the observed changes in the intervention group were higher than the control group. Conclusion: Despite the specific features of the educational model, the plan can be effective in improving the quality and quantity of pregnancy care as a continuous intervention in all health care centers.
