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:
Up to 80–90% fewer depot visits linked to SIM handling
Zero onboard hardware changes when switching mobile networks
Hours rather than weeks needed to change network providers or profiles fleetwide
Multi‑network flexibility that can cut roaming and cross‑border data costs by 15–40%, depending on region
Higher service uptime, as network issues can be mitigated with profile changes rather than equipment swaps
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:
Physical SIM swaps in depots
Night‑time access windows and service disruption
Slow and manual processes that are difficult to progress/scale
Onboard digital services are becoming more critical as we connect more fleets together. These approaches increasingly limit operational agility.
What SGP.32 enables
SGP.32 is designed specifically for IoT and fleet deployments, rather than consumer devices. It supports:
Remote sim provisioning and lifecycle management across large numbers of devices
Multiple network profiles per device, stored securely on an eSIM
Fleet‑wide changes without touching hardware
Instead of being locked into connectivity decisions made at installation time, operators can adapt networks dynamically as requirements evolve.
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:
The eSIM platform manages secure profile delivery and lifecycle actions
Fleet Connect links connectivity to real assets such as vehicles, routes, and depots
Concepts such as geofencing or time based‑ rules can be applied at fleet level
This separation ensures a standards-based foundation, while enabling workflows that reflect how mobility fleets actually operate.
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:
Run traditional SIMs and eSIMs simultaneously
Start with removable eSIMs where appropriate
Evolve hardware platforms over time without any disruption
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:
Reducing time spent touching hardware
Increasing flexibility to adapt networks as conditions change
Treating connectivity as an operational tool rather than a constraint
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.
