In São Paulo, passengers relying on the metro system have expressed frustration over inadequate mobile phone signals and internet access within stations and tunnels. A report by TV Globo highlighted that connectivity varies significantly across different metro lines, with some underground segments lacking any service at all. For example, despite claims from ViaMobilidade about improved services along the Line 5-Lilás, passengers like Rubens Mira report that connectivity remains inconsistent and unreliable in several areas.

Passengers on Line 4-Amarela, operated by the same group, echoed similar sentiments, stating that connectivity fluctuates depending on the station and journey. Flávia Carvalho, a security professional, remarked that while some parts of the metro offer service, many areas still experience dropouts, especially during transit. This issue not only inconveniences daily commuters but also raises concerns about safety and communication in emergencies.

The ongoing connectivity challenges reflect a broader problem faced by urban public transport systems in large cities, where the demand for consistent mobile service continues to grow. As metropolitan areas expand and technology becomes an integral part of daily life, the inability to provide robust communication infrastructure could hinder the overall public transportation experience and potentially impact ridership levels. Thus, addressing these connectivity issues could be crucial for both the metro operators and users in maintaining reliable service.
