Mobile government is an emergent phenomenon that represents a solution for many countries to reach their citizens and improve delivery of government-to- citizens’ services (G2C). Despite the fact that mobile government benefits are very promising; there are some factors that determine success or failure of mobile government applications. In this study, a systematic review of previous studies using a meta-analysis method was undertaken and a conceptual success factors model for mobile government to citizen services (G2C) was created. Furthermore, the second phase of this study was a survey with 40 academics to validate the use of meta-analysis and validate and refine the conceptual model.
