  The relevance of mobile working is steadily increasing. Based on new mobile
devices (e.g. smartphones) and their innovative functionalities, an increasing
amount of data is being made available ubiquitously. As a result, the growing
diffusion of smartphones offers new potential for enterprises. Current mobile
devices and related mobile networks have reached a high level of maturity.
Thus, the organizational aspects of mobile work have become a focal point of
interest for enterprises as well as for academics. This research article
addresses the question: How does context influence the choice of communication
channels of mobile knowledge workers? An explorative research approach is used
to collect and analyse 418 communication incidents, which were initiated by
mobile knowledge workers. The results indicate that (1) the context (e.g.
travelling on trains) influences the usage of communication channels and (2)
smartphones enable the usage of communication channels (e.g. email) in certain
contexts.
