The purpose of this study is to investigate factors that influence the effectiveness of mobile bankingrnadoption in the case of commercial banks in Ethiopia. A sample of 400 respondents was drawnrnfrom both public and private banks in Addis Ababa, Ethiopia where a structured questionnairernwas distributed to these samples. However, the response rate from among the intended samplesrnwas only 95.5% therefore; around 382 responses were found to be workable by this study. SPSSrnV 24.0 was used to analyze the data collected and to test the hypotheses put forward. The findingsrnof this study then show that factors namely convenience and relative advantage have a positivernand significant relationship with mobile banking adoption in Ethiopia which led to, the acceptancernof hypothesis two and four. From Hypothesis three, perceived risk was found to have a significantrnnegative influence on mobile banking adoption, meaning hypothesis three was supported. Whereasrnhypothesis one trust has no significant relationship with the dependent variable mobile bankingrnadoption. And this was found by running multiple linear regressions on SPSS. The testing of thernfifth and final hypothesis, which set out to find any significant difference between the differentrnfactors (trust, convenience, risk and relative advantage) of public and private banks show thatrnthere is no significant difference on trust, convenience and relative advantage between public andrnprivate banks but perceived risk was found to be significantly different between public and privaternbanks in Ethiopia. This led to the partial acceptance of the fifth hypothesis. These findings arernbeneficial for both public and private banks in Ethiopia to identify factors that influence therneffectiveness of mobile banking adoption. The study recommends more studies on mobile bankingrnadoption to be conducted in other areas of the country to find out if there could be any similarities.
