CapTemp Lda. is a specialist in environmental monitoring solutions for temperature-sensitive logistics. With its G-LogBOX system, the company enables precise and continuous monitoring of temperature and location data in mobile applications such as refrigerated trailers and cold storage transport.
To ensure reliable data transmission under real-world conditions, CapTemp relies on M2M SIM cards from WhereverSIM.

“Even small temperature deviations can lead to significant product losses. That’s why uninterrupted monitoring and reliable data transmission are essential for transporting pharmaceuticals or perishable goods.” explains Carlos Domingues, Founder and CEO at CapTemp. “Our G-LogBox is specifically designed for the needs of cold chain logistics, ensuring this reliable monitoring.”
The small devices are installed in refrigerated trailers and mobile units, where they continuously collect environmental data such as temperature and location.
However, these mobile environments present several challenges:
“To ensure reliable condition monitoring, we needed a connectivity solution that works seamlessly in motion but without any manual intervention.” so Carlos Domingues.
To guarantee uninterrupted data transmission, CapTemp integrates M2M SIM cards from WhereverSIM into its G-LogBOX. The SIM cards enable:
Thanks to this connectivity, the sensor data collected is transmitted directly to the cloud platform via NB-IoT/LTE-M, where it can be monitored, analyzed, and documented in real time.

By combining CapTemp’s monitoring technology with WhereverSIM’s connectivity, logistics providers benefit from a highly reliable solution for cold chain logistics. The collaboration between both companies demonstrates how reliable connectivity is a key enabler for modern IoT applications in logistics.
Looking ahead, Domingues concludes: “WhereverSIM has become an important part of our solution. We are very happy with the collaboration and especially with the reliability we can deliver to our customers. As our projects continue to grow, we look forward to further expanding this partnership.”
