This paper proposes a multistage three- way decisions of spam SMS(short messaging service) filtering model. By using different granularity information to express the SMS,with the sequence decisions(i.e.,multistage,multiple steps in decision-making),at different decision-making stages,based on different information granularity respectively three-way decision-making,those can avoid to make irrational decisions when the message size is too big or insufficient information. If the information does not meet the current decision-making conditions,this model can add enough granularity information before making a further decision. Finally,the experimental results prove the rationality and validity of the model.
