Introducing eSIM for mobility fleets

Simpler, more flexible connectivity operations for rail and bus operators.

Motion Applied has launched an SGP.32 eSIM service within the Fleet Connect™ software, delivered alongside our EDGE connectivity hardware, to simplify and modernise connectivity operations for rail and bus fleets.

Built on the GSMA SGP.32 standard for IoT and fleet deployments, the service enables connectivity to be treated as a flexible, software-driven‑ operational capability rather than a fixed hardware decision.

Fleet Connect™ and EDGE Rail now support GSMA SGP.32-based eSIM capabilities, enabling operators to remotely manage network profiles across large vehicle fleets, without physical access to vehicles, equipment, or roof‑mounted antennas.

This allows connectivity to become a software-defined operational asset rather than a hardware constraint:

Addressing a growing operational challenge

Mobility fleets operate across borders, through highly variable coverage environments and over lifecycles measured in years.

Yet when coverage, cost, or commercial agreements change, updating connectivity can still involve:

What SGP.32 enables

SGP.32 is designed specifically for IoT and fleet deployments, rather than consumer devices. It supports: 

Why this matters for rail and bus fleets

Dramatically fewer depot visits
By enabling remote profile updates, SGP.32 removes the need for physical SIM handling once operational, lowering cost, operational risk, and service disruption. For a fleet of 500 vehicles, removing SIM‑related depot visits can save hundreds of engineering hours per year

Simpler cross border operation
Devices can hold local profiles for different regions, supporting better performance and cost control as vehicles move across borders, without manual intervention. This can reduce cross‑border connectivity costs by 20–40%

A stronger foundation for constant connectivity
Modern systems aggregate multiple networks to improve consistent connection and throughput. SGP32 strengthens this model by ensuring the right profiles are available on the right devices, improving the quality of the underlying network inputs.

Well suited to concealed and roof mounted hardware
For connectivity hardware used in rail deployments, including Motion Applied’s EDGE Rail platforms, which are typically roof mounted or concealed and installed once, SGP.32 minimises the need to revisit SIM hardware and aligns with real-world‑ rail and bus maintenance constraints.

Fleet Connect™: adding fleet intelligence on top of the standard

SGP.32 provides the standards based eSIM lifecycle infrastructure. Fleet Connect™ adds the fleet intelligence and operational context.

In practice:

Secure, controlled and built for scale

SGP.32 is designed with enterprise operations in mind. Profile changes are centrally orchestrated, securely executed, and auditable, supporting large‑scale fleet operations rather than ‘last minute’ device management.

A practical, hybrid path forward

Motion Applied supports a hybrid adoption model, allowing operators to: 

This approach allows customers to adopt SGP.32 practically, without forcing a disruptive transition.

Looking ahead

For mobility fleets, SGP.32 is not about adopting new technology for its own sake. It is about:

Motion Applied’s Fleet Connect™ platform, combined with SGP.32, creates simpler border operations, fewer depot visits, and smarter connectivity management at a fleet scale.

Motion Applied is working toward one of the earliest commercial mobility deployments using the SGP.32 standard, with initial rollouts planned for Spring 2026.

Meet Motion Applied at MWC Barcelona (3–5 March) to discuss how SGP.32 can support your fleet connectivity strategy.

With the new Fleet Connect™ SGP.32 eSIM service, we’re enabling fleets to stay on the best available, most cost effective mobile networks, and to evolve their connectivity over time without hardware visits. Combined with EDGE Rail active antennas and Fleet Connect’s hybrid approach, which maximises terrestrial mobile coverage together with LEO satellite communications, we deliver a more resilient, forward looking connectivity solution for fleets.
