From Supply Chain to Implementation Challenges

The 3G sunset is in full force. Over 350,000 vehicles were left unprepared for AT&T’s shutdown in February, with remaining major U.S. wireless carriers like T-Mobile and Verizon to fast follow in the coming months. This means thousands of fleets are racing to replace 3G technology in order to maintain safety, compliance, and visibility into operations. Given increasing supply chain constraints on 4G compatible devices, it’s vital for you to understand the impact on your fleet so you can act quickly.


While implementing new technology can be a big undertaking, thoughtfully planning ahead will ensure a smooth rollout. What’s more, the 3G sunset can be a chance to re-evaluate your current technology infrastructure and identify hidden opportunities to advance your fleet’s safety and efficiency. That’s exactly how Carroll Fulmer Logistics leveraged their 3G transition.

With over 70 years of experience, Carroll Fulmer is a full-service transportation and logistics company serving over 14,000 partners across 48 states. For them, the 3G sunset meant having to replace ELDs for over 450 trucks to maintain compliance with the FMCSA ELD mandate. Their Director of Information Technology, Mike Prokosch, saw this as an opportunity to go beyond ELD compliance and digitally transform their operations with Samsara’s Connected Operations Cloud, while saving over $195,000 in hardware costs with the adoption of new mobile technology.
