Compliant with the GSMA SGP.32 standard1, the new solution enables customers to ship connected devices anywhere in the world with one single, pre-integrated eSIM from Thales, then seamlessly activate the correct local connectivity profile remotely, eliminating the need for any physical access to it. This results in faster launches and simpler logistics for global IoT deployments. It also enables AT&T and its customers to easily manage connectivity policies, diagnostics, and subscription changes entirely over the air, through a single unified industry-certified interface.

This solution also adds advanced automation to simplify the remote eSIM management of large numbers of devices. It automates complex tasks-such as switching subscriptions or updating fleets rules-so enterprises can spend less time on logistics and operations, while bringing new products and services faster to market.

Thanks to these advanced features, Thales' eSIM solution (TAC) gives companies the flexibility to localize within AT&T network partners or adjust devices' subscriptions across large fleets without hardware changes, helping optimize costs, supply chains, coverage, and performance.

The service is now available for commercial use and supports customers worldwide.

"We are entering a new era for remote eSIM Provisioning, ready to power billions of IoT devices, and we are proud to collaborate with AT&T in delivering smarter and safer IoT connectivity around the world,"said Eva Rudin, EVP Mobile Connectivity Solutions at Thales. "With Thales Adaptive Connect, we're ensuring that every connected device benefits from strong security, reliable service, and simplified management - from the first connection and throughout its lifetime."
