The limitations of legacy SGP.02 IoT connectivity
Fragmented Supply Chain
SIMs are tied to specific carriers, forcing multiple regional SKUs and increasing operational complexity.
Outdated Activation
Remote devices using legacy M2M standards rely on SMS for profile swap procedure initiation. This requires complex integrations for binary SMS delivery.
Vendor Lock-In
Rigid, operator-controlled architecture makes switching carriers slow, complex, and expensive.
Slow deployments
Extremely lengthy and complex MNO integration project slow down deployments and drain engineering resources.

Why fleet operators choose 1GLOBAL eSIM IoT Manager (eIM)
Devices perform over-the-air (OTA) self‑configuration on first activation, supporting a single‑SKU global deployment model, minimizing deployment cost and time-to-market.
Operator Independence
1GLOBAL eSIM IoT Manager enables full carrier flexibility, giving you freedom to decide who operates the profiles, when, and where. This helps avoid vendor lock-in and ensures optimal connectivity at all times.
True Single SKU
One universal eSIM enables global IoT deployments without regional SKUs - reducing manufacturing overhead and simplifying fleet‑wide profile switching. Connectivity is controlled remotely with automated deployment on arrival for simple, cost-effective logistics.
Zero Touch Provisioning
Devices self‑configure over‑the‑air (OTA) immediately upon activation, minimizing manual setup, accelerating deployment and reducing field costs.
Business Continuity
1GLOBAL eSIM IoT Manager (eIM) is compatible with a wide range of devices. This means there are no constraints for low power devices and it is optimized for asynchronous provisioning. New connectivity profiles can be added and updated when required as your operations scale.

Put control in the hands of the Enterprise
GSMA SGP.32 Remote SIM Provisioning architecture
1GLOBAL’s SGP.32-compliant solution gives businesses full control of their fleet.
The main component of SGP.22 (Consumer eSIM) infrastructure, SM-DP+, is reused in SGP.32.
IPA (IoT Profile Assistant) is the device-side software element that enables communications between eSIM, eIM and SM-DP+.
eIM secures the installation and management of eSIM profiles, controls the remote management of the eSIM profile lifecycle.
eIM platform is equipped with end user portal UI for single operations and with API for full-scale eSIM profile management automation.

Frequently asked questions
SGP.02 relies on complex operator-controlled infrastructure and SMS to initiate updates, often causing lock-in and failures.
SGP.32 introduces a more flexible architecture, giving OEMs and fleet operators full control through an eSIM IoT Manager (eIM) and using reliable IP-based data protocols. This makes it faster, more scalable, and better suited for battery-powered IoT devices.
No. With 1GLOBAL's IPA-e solution, the necessary configuration is embedded directly into the eSIM chip. This allows many existing devices to become SGP.32-compliant just by swapping the SIM card - no hardware redesign required.
Yes. The 1GLOBAL eSIM IoT Manager supports a true single-SKU approach, allowing manufacturers to ship one device globally and provision the appropriate local connectivity profile remotely after deployment.
Yes. The eIM platform enables remote installation, activation, and management of eSIM profiles over the air, allowing enterprises to change connectivity providers without physically accessing devices.
