IN Brief:
- Wireless Logic will demonstrate SGP.32 remote provisioning and eSIM profile switching at Microelectronics UK on 29–30 September.
- The GSMA architecture supports remote lifecycle management of network profiles across constrained and unattended IoT devices.
- The demonstration will combine connectivity management with sensor data, digital-twin software, and anomaly and threat detection.
Wireless Logic will demonstrate SGP.32 eSIM provisioning and profile management at Microelectronics UK in London next month, showing how cellular connectivity can be changed remotely across distributed IoT equipment. The company will use the event to examine profile switching, fleet management, regulatory requirements, and the practical integration of connectivity with deployed sensor systems.
The demonstration will take place at ExCeL London on 29 and 30 September. Marco Corona, IoT solution sales director for embedded channel and strategic partnerships at Wireless Logic, will also deliver a session on SGP.32 on 29 September, focusing on the technical and operational problems enterprises encounter when deploying connected equipment across several countries and mobile networks.
SGP.32 is the GSMA’s remote SIM provisioning architecture developed specifically for IoT devices, including equipment with restricted connectivity or little to no user interface. That distinguishes it from consumer eSIM processes, where a person can usually interact directly with a handset during activation, scan a code, or intervene if provisioning fails.
Industrial equipment rarely offers the same convenience. Sensors, gateways, meters, tracking devices, and embedded controllers can remain installed for years in inaccessible locations, while some operate intermittently or spend much of their time in low-power states. Replacing a physical SIM across a large installed fleet can therefore turn a relatively small connectivity change into a costly field-service exercise.
SGP.32 allows eSIM profiles to be managed remotely through an architecture designed around those constraints. The eSIM IoT Remote Manager, or eIM, orchestrates profile-management activity, while the IoT Profile Assistant, or IPA, provides the device-side functions used to interact with the eUICC. An SM-DP+ backend stores and securely delivers operator profiles.
Profiles can consequently be downloaded, enabled, disabled, or deleted without replacing the SIM hardware. For an equipment manufacturer, that can separate the choice of cellular network from the point at which the product is assembled. A common hardware configuration can potentially be manufactured in volume and provisioned later for the network or market in which the device will operate.
The same capability can be used after deployment. Coverage changes, operator contracts expire, network technologies are retired, and permanent-roaming restrictions vary between markets. Remote profile switching gives operators another way to respond to those changes without dispatching an engineer simply to exchange a SIM card.
Corona said: “At the show, we will demonstrate exactly how SGP.32 enables seamless remote provisioning, profile switching at scale and management across global fleets.”
The provisioning standard does not remove the wider system-engineering problem. Device firmware, the eUICC, profile-management infrastructure, network credentials, security policies, operator relationships, and the enterprise’s own management systems still have to work together. A failed profile change on an inaccessible device is considerably more serious if it also removes the communications path needed to recover the equipment.
Resilience therefore depends on how provisioning policy is implemented as much as on the presence of an eSIM. Engineers need to consider which profiles remain available, how switching decisions are triggered, how failed transactions are handled, and what connectivity survives when a preferred network is unavailable. Devices expected to remain in the field for five, ten, or more years also need an architecture capable of accommodating commercial and regulatory changes that cannot be known at manufacture.
The current GSMA SGP.32 v1.3 technical specification was published in May 2026 and remains active alongside version 1.2. It covers remote provisioning and management of eUICCs in network- or user-interface-constrained IoT devices, together with the associated architecture, interfaces, and security functions. The maturity of the specification is increasingly shifting attention from defining the architecture towards deploying it at fleet scale.
Wireless Logic will connect that provisioning discussion with a broader IoT demonstration at Microelectronics UK. Trial SIMs will be used to show profile swapping alongside Kheiron, a digital-twin platform consolidating data from multiple sensors. The demonstration will expose measurements including temperature, humidity, and occupancy through a common view.
That combination is more representative of an industrial IoT system than demonstrating eSIM switching in isolation. Connectivity exists to move operating data into an application, so a profile change has to preserve the device identity, security controls, telemetry flows, and application availability expected by the equipment operator.
Wireless Logic will also demonstrate its Anomaly and Threat Detection capability, which is intended to improve visibility into activity across connected devices. Remote provisioning increases the number of connectivity functions that can be changed without touching the hardware, making monitoring of device behaviour and network activity an important part of managing the resulting fleet.
For embedded designers, SGP.32 consequently affects decisions made well before a device reaches the field. Hardware has to support the chosen eSIM implementation, firmware must accommodate the provisioning architecture, and management systems need to treat cellular connectivity as a lifecycle function rather than a fixed manufacturing parameter.
Inventory management can change as well. Maintaining separate hardware stock for different operators or destination countries adds complexity to manufacturing and distribution, particularly when products are built centrally before their final market is known. A remotely provisioned architecture can reduce some of that fragmentation, although network certification, radio requirements, and regional product rules still remain.
Microelectronics UK gives Wireless Logic an opportunity to demonstrate those operational details rather than announce a new version of the standard. The engineering significance sits in the move from specifications and pilot deployments towards routine fleet management. Once connected equipment is installed across several countries, changing a network profile remotely is considerably cheaper than finding the device, opening the enclosure, and replacing connectivity hardware by hand.
