On March 24, 2025, Claro customers across Brazil reported significant difficulties accessing mobile internet and making phone calls as the operator experienced widespread outages. Major cities affected by the disruption included Porto Alegre, São Paulo, Rio de Janeiro, Brasília, Curitiba, Campinas, and Londrina. This situation left many users frustrated and unable to utilize essential services.
The issues began early in the morning, with reports filtering into Downdetector as early as 5:40 AM. The platform, which tracks service outages, noted a sharp increase in complaints, peaking at around 8 AM when more than 1,700 reports were filed. Users cited problems primarily related to mobile internet access (82%), followed by mobile telephony (10%) and general failures (8%).
Social media platforms were flooded with complaints. One user on X (formerly Twitter) expressed their frustration, saying, "I restarted my phone three times thinking it was just me, and when I got to work, I found out Claro was down. Shameful!" Another user lamented, "I pay R$ 110 for my plan, and Claro is delivering this service. It’s getting increasingly challenging with these cell service providers in Brazil. I don’t know what else to do!" Both comments demonstrate the high expectation customers have for reliable service.
The peak reporting time coincided with the morning commute for many users, who were no doubt relying upon their mobile devices for work-related tasks. Experts suggest that the extensive failures negatively impacted not only personal communications but also essential services such as transportation apps, mobile payments, and telecommuting platforms.
In light of the growing complaints, Claro confirmed the technical difficulties on its official social media account, stating, "Claro is experiencing technical problems," without elaborating on what caused the instability. The company has engaged its technical team to investigate and address the issues, but as of now, no timeline for a resolution has been shared.
Customers expressed their concern over the lack of information from Claro regarding the outages. Many took to social media to share their grievances, further amplifying the operator's failure to communicate effectively. Some users reported that their entire morning routine was disrupted due to the outages, noting the stark contrast between their service expectations and the reality of their experiences.
The Downdetector map showcased instability nationwide, signaling a widespread problem affecting customers from the southernmost regions of Brazil up to the northern parts. While some users in certain regions reported isolated service interruptions, numerous clients across different cities echoed similar frustrations.
The trend of complaints and inquiries about Claro's service was reflected not only in user reports but also through search trends, with terms like “Claro down” and “is Claro out today” seeing a surge in interest on Google. It clearly shows how critical mobile connectivity has become in today's digital age and how quickly consumers turn to online platforms to seek answers when service fails.
As customers await clarification from Claro regarding the root cause of the outages and a timeline for restoring service, some experts suggest that users consider having secondary SIM cards to avoid being left without mobile access in the future. This precaution can serve as a safety net to ensure that connectivity remains intact in emergencies or when primary services fail.
In summary, Claro’s inability to deliver consistent and reliable service on this day has left thousands of customers frustrated and voicing their concerns openly. The expectation for communication from the service provider is paramount in helping users understand what is happening and when they can expect a return to normal service. Until Claro provides clearer guidance, customers are likely to remain agitated and disappointed.
As of now, there is no official timeline for when Claro's mobile internet services will return to normal, and the situation continues to affect consumers who depend on mobile connectivity for their daily activities.
