In migration studies, there is an increasing interest in understanding how migration processes are shaped by different forms of brokerage and mediation. We relate these debates to the everyday struggles of migrants in the city of Athens. In so doing, we propose a shift from the all-encompassing view on infrastructures, that is, as systematic entities of facilitation/control to the infrastructuring practices of migrants. This implies a focus on how migrants create dynamic social platforms, and how these platforms relate to formal infrastructures and industries. We analyse these infrastructuring practices through a conceptual lens of resonance that is sensitive to the constitutive (how things, people and processes are brought together) as well as travelling capacities of these practices (how the platforms shift to other places). With an ethnographic approach, we create in-depth insights into the ways in which migrants mediate im/mobility in the urban environment of Athens through infrastructuring practices. The paper concludes by reflecting on the promises and limitations of the infrastructuring practices as sites of solidarity. We thereby argue that there are many links to make within the mobile commons debate. At the same time, our findings highlight that the transformative potential of infrastructuring practices does not always go along with a clear claim on solidarity.

在移民研究中，人们越来越有兴趣了解不同形式的中介和中介如何影响移民过程。我们将这些辩论与雅典市移民的日常斗争联系起来。在这样做时，我们建议从对基础设施的包罗万象的观点，即作为促进/控制的系统实体转变为移民的基础设施实践。这意味着关注移民如何创建动态的社交平台，以及这些平台如何与正式的基础设施和行业相关联。我们通过对构成（事物、人员和流程如何结合在一起）以及这些实践的旅行能力（平台如何转移到其他地方）敏感的共振概念镜头来分析这些基础设施实践。通过人种学方法，我们深入了解移民通过基础设施实践在雅典城市环境中调节固定/流动性的方式。本文最后反思了作为团结场所的基础设施实践的前景和局限性。因此，我们认为在移动公共领域辩论中有许多联系需要建立。与此同时，我们的研究结果强调，基础设施实践的变革潜力并不总是伴随着对团结的明确主张。因此，我们认为在移动公共领域辩论中有许多联系需要建立。与此同时，我们的研究结果强调，基础设施实践的变革潜力并不总是伴随着对团结的明确主张。因此，我们认为在移动公共领域辩论中有许多联系需要建立。与此同时，我们的研究结果强调，基础设施实践的变革潜力并不总是伴随着对团结的明确主张。
