Preventing IoT Blackouts: The Power of Global Roaming SIM Cards


When SIM Cards Fail

Recently, AT&T, the American telecommunications giant, experienced a significant network outage, affecting tens of thousands of customers. In a scenario akin to a frozen moment in time, countless lines fell silent. reported 74,000 outages in just 24 hours, with disruptions noticed only after many had their third cup of coffee.

Widespread Impact

Cities like Houston, Chicago, Dallas, San Antonio, and Atlanta faced unexpected radio silence. While other providers like Verizon and T-Mobile were less affected, the incident highlighted a critical vulnerability: the potential for widespread blackouts in the Wireless IoT ecosystem. Imagine if such disruptions became routine, leaving connected devices and essential infrastructure in a digital void.

The Risks in Wireless IoT

This incident underscores a significant risk in the Wireless IoT realm. A minor glitch in the mobile network can halt communication, impacting not only personal interactions but also critical systems.
