This study examined the factors that influence consumer satisfaction with mobile telephone use in Malaysia. The validity of the study's constructs, criterion, and content was confirmed. Construct validity was verified through the factor analysis with a total variance of 73.72 percent explained by all six independent factors. Content validity was verified with the development of the independent and dependent variables based on the definitions of the constructs from various national and international literature, while criterion validity was confirmed through the stepwise multiple linear regression analysis between dependent and independent variables. The study findings show that an increase in mobile phone peer chatting and family coordination will significantly increase OMPS while an increase in mobile phone radio-frequency radiation health concern, public disturbance, social interruption, and road accidents will significantly decrease OMPS.
