This article investigates how text messages and mobile phone calls interrelate as parts of continuous communication sequences. Based on the recorded mobile communication of 14-year-olds in Denmark and a conversation-analytic approach, the article will show that after a text message in a continuous communication sequence, four different types of conversation may follow: the answer, the reminder, the resumption of conversation and the confirmation. In itself, the change from text message to conversation requires no interactional efforts from the participants. However, changes (...) of mode are related to the different communicative possibilities the text message and the phone call offer: text messages and calls have distinct formal qualities that govern their uses, and participants in a given sequence move between the two modes, exploiting the potential of each as they ascribe meaning to the written and spoken media.
