We focus on the discussion about the proposal of shifting to a post paid mobile Internet tariff model based on usage, and its impact on universal use and service access for the poor sectors of the country. This proposal aims to address the problem of cellular data network saturation, by charging per downloaded kilobyte instead of allowing unlimited use. We analyze the position of important actors using the Advocacy Coalition Framework. The study reveals the absence of public policies on IT connectivity and infrastructure in Costa Rica. Based on the results, we conclude that the proposed change does not solve the saturation problem, but rather imposes limitations on access and usage for low-income people, generating social exclusion and digital divide.
