The authors examine the use of mobile money in the context of cross-border remittances in West Africa. Relying on mixed methods and a multi-sited empirical strategy they look at both the sending and receiving conditions of mobile money transfers. By looking at money as socially embedded and the role of migrants in the production of a transnational space, their results highlight that uptake and usage of mobile money for remittances are shaped by a transnational living pattern. At the same time, mobile money also contributes to strengthening and reshaping this pattern. By showing that conversion of virtual money to cash may be performed by brokers that live far away from the end recipient, the paper highlights an important gap between spatial distribution of mobile money infrastructure and the social mediation that supports e-money flows. Cash-based transactions, in turn, are shown to play a key role in the social mediation dynamic.
