The use of mobile learning (m-learning) is gaining attention in the higher learning institutions. However, trustworthy towards the effectiveness of the learning sessions via m- learning is still questioned such as the issues of reliability, accuracy and validity of its content deliverables. Therefore, this exploratory research is aimed to identify the trust contributing factors of m-learning among students in the local public universities. Two models of trust factors which are build-trust factors and sustain-trust factors were examined. The data were collected via self-administered survey and Exploratory Factor Analysis is used to analyse the data. The findings showed that in terms of demographic statistics the more trustable m-learning users among the students are ‘male’ users; age between ‘28-38’ years old, period of using was more than five years and majority are iPhone users. Meanwhile, the trust- build factors that are able to influence users to trust the m-learning were familiarity, information quality, interaction, feasibility, goal setting, third party recognition, attractive reward, and rules while factors such as consistency, reliability, experience sharing, integrity, security control, community building, open communication, site quality, feedback, time, and external auditing contributed to sustain the trust. Future research proposed a thorough investigation on aforementioned factors found for m-learning trust model enhancement.
