AT&T and Eseye launched AT&T Global SIM Advanced, a managed multi-IMSI eSIM service designed to provide global cellular connectivity for IoT devices, featuring Eseye’s AnyNet eSIM and Infinity connectivity management platform. The rollout aimed to reduce reliance on permanent roaming by enabling devices to attach to local networks where needed.
Specialist providers like Aeris and floLIVE also introduced platform and core-network approaches at MWC Barcelona, with offerings that include carrier-agnostic connectivity orchestration, SIM management and real-time billing. Aeris highlighted its global carrier partnerships and value-added services, while floLIVE emphasized its in-house IoT core to meet regulatory and latency needs.
For enterprises, these made-for-IoT solutions simplify production SKUs, streamline supply chains and ensure compliant, resilient connections across markets, enabling reliably managed device fleets and supporting the broader trend toward unified global IoT networks.

Trend Themes
-
Managed Multi-imsi Esims — Wider deployment of eSIMs with multiple IMSIs creates scope for platforms that dynamically optimize cost, compliance and latency across jurisdictions.
-
Carrier-agnostic Connectivity Orchestration — Neutral orchestration layers that abstract carrier relationships enable new service models around seamless failover, billing consolidation and policy-driven routing.
-
Iot Core-network Virtualization — Shifting core network functions into cloud-native, vendor-agnostic stacks opens possibilities for low-latency, regionally compliant connectivity services tailored to device classes.
Industry Implications
-
Industrial Iot and Logistics — Global fleets and supply chains stand to benefit from resilient, locally-attached connectivity that reduces downtime and simplifies cross-border device provisioning.
-
Telecommunications Operators — Operators can encounter competitive pressure and revenue opportunities from managed IoT connectivity bundles and wholesale orchestration partnerships.
-
Enterprise Device Manufacturing — Manufacturers face product-line consolidation and lifecycle support innovation as embedded multi-IMSI eSIMs enable single-SKU global devices with differentiated connectivity features.
