Resumen: This article aims to answer several questions that seem to me of vital interest and that are closely linked to the educational world and its progress using technological support. First of all, we will discuss how and when the mobile phone appears as an educational resource, and how it influences the classroom. On the other hand, I will discuss the various positive effects of the use of smart devices in the teaching-learning process, as well as their limitations. Finally, reference will be made to an example of an educational project based on m-learning, which will show how this type of tool is a very effective pedagogical resource in the classroom.
