Mobile government is considered as an emerging technology that has been used in Saudi Arabia in order to enhance communication between the government and its citizens, it can also be considered as a mechanism through which the government can effectively respond to their needs and expectations. The current study seeks to propose and validate Mgovernment adoption model to fully understand the varied variables affecting the adoption behavior. This model is based on Technology Acceptance Model (TAM) and DeLone and McLean Information Systems Success Model. The researchers will depend on a descriptive survey approach using structured questionnaires to investigate the extent of M-government acceptance by Saudi users. Structural equation modeling will be used as a method for statistical data analysis.
