Why IoT eSIM SGP.32 is critical across key IoT verticals

As IoT deployments scale globally, connectivity requirements are evolving. Organisations now operate large, long-lived and geographically distributed device fleets, often in environments where physical access is limited or costly. These deployments require reliable connectivity, minimal manual intervention and the flexibility to adapt over time.

IoT eSIM (SGP.32) addresses these challenges by enabling secure remote lifecycle management of connectivity. Built on GSMA standards, it allows operator profiles to be provisioned, updated and controlled without physical access to the SIM.

Combined with melita.io’s MNO-backed infrastructure, global coverage and multi-network access with automatic failover to the strongest available signal, IoT eSIM SGP.32 supports a scalable, software-driven connectivity model. Unlike models that depend on third-party providers, this delivers direct control, higher reliability and consistent performance across global deployments.

Smart metering (energy, water, gas)

Smart meters are deployed for 10 to 15 years in locations that are difficult to access, where network conditions and regulations may change over time.

With IoT eSIM SGP.32, melita.io enables utilities to:

• provision connectivity remotely at installation
• update operator profiles without site visits
• maintain uninterrupted service across the full lifecycle

Real-world scenario

A utility manages thousands of meters across regions and updates connectivity remotely, avoiding field visits while maintaining continuous service.

Smart cities and municipal infrastructure

Smart city deployments combine multiple systems such as lighting, traffic management and environmental monitoring, all requiring long-term flexibility.

IoT eSIM SGP.32 enables:

• centralised connectivity management across city-wide deployments
• scalable onboarding of new services and devices
• long-term adaptability as requirements evolve

Real-world scenario

A municipality manages connected infrastructure from a single platform, ensuring consistent performance across services while simplifying operations.

Industrial automation and manufacturing

Industrial environments require secure, stable and predictable connectivity across sites, where downtime has a direct operational impact.

IoT eSIM SGP.32 supports:

• seamless connectivity across global locations
• remote lifecycle management without disruption
• secure control aligned with enterprise policies

Real-world scenario

Production systems automatically connect to the strongest available network across sites, ensuring uninterrupted operations without manual intervention.

EV charging infrastructure

EV charging networks rely on continuous connectivity for authentication, billing, monitoring and diagnostics.

IoT eSIM SGP.32 enables operators to:

• manage connectivity across the full infrastructure lifecycle
• support cross-border deployments across multiple networks
• eliminate physical SIM handling
• maintain consistent performance at scale

Real-world scenario

A charge point operator manages thousands of stations across countries, maintaining reliable connectivity through remote profile management and multi-network access.

Logistics and fleet operations

Logistics and fleet solutions depend on uninterrupted connectivity across regions and networks.

IoT eSIM SGP.32 enables:

• continuous connectivity across borders
• reduced reliance on a single network
• centralised fleet-wide management

Real-world scenario

A logistics provider tracks assets across countries, adjusting connectivity remotely to maintain performance and optimise costs.

Asset tracking and condition monitoring

Tracking devices operate in mobile or remote environments where efficiency and long-term reliability are critical.

IoT eSIM SGP.32 supports:

• remote SIM provisioning
• long-term deployments without replacement
• global connectivity from a single platform

Real-world scenario

A company tracks high-value assets globally, adapting connectivity remotely as devices move across regions without physical intervention.

Critical infrastructure and public services

Critical infrastructure requires secure, resilient and centrally controlled connectivity with minimal tolerance for disruption.

IoT eSIM SGP.32 provides:

• secure GSMA-compliant lifecycle management
• remote operational control
• adaptability for regulated environments

Real-world scenario

An infrastructure operator monitors distributed assets and adjusts connectivity centrally, ensuring continuous service without on-site access.
