T-Mobile's legacy supply chain infrastructure couldn't support their ambitious growth strategy or deliver on their customer-centric brand promise. The Sprint merger intensified this challenge, presenting complex integration demands while maintaining business continuity. With supply chain operations managing $13B annually across 19,000+ stores, the company needed a digital transformation that could integrate disparate systems, enable new omnichannel capabilities, and support the rapid deployment of 5G infrastructure—all while enhancing the customer experience that differentiated their brand.

Spinnaker SCA, a Publicis Sapient company, designed and implemented a comprehensive digital supply chain ecosystem that fundamentally changed how T-Mobile manages inventory, fulfills orders, and serves customers. The solution included deploying a highly automated, multichannel distribution center for all US mobile device and accessory fulfillment, modernizing their 5G network supply chain, and re-architecting their reverse supply chain operations.

Key innovations included consolidating all device and accessory inventory to a centralized distribution center, creating a closed-loop supply chain with end-to-end return tracking to eliminate fraud, and enabling seamless omnichannel experiences (buy online/pick up in-store, ship from store, return in store). The architecture specifically addressed the challenge of integrating Sprint and T-Mobile inventory systems to create a unified customer experience regardless of which brand's store a customer visited.

The transformed supply chain platform positioned T-Mobile for unprecedented growth following their $37 billion merger with Sprint. With their new digital capabilities, T-Mobile rapidly adapted to changing consumer behaviors during COVID-19, accelerating omnichannel services like contactless delivery, curbside pickup, and same-day delivery. The platform's flexibility allowed T-Mobile to give customers true choice in how they receive products while maintaining operational efficiency at scale.
