Scale IoT faster with an eSIM management platform

Provisioning SIM cards through manual workflows was manageable when fleets were small and connectivity needs were simple. However, as organizations scale their connected devices across regions, networks, and various use cases, traditional SIM provisioning has become a bottleneck—slow, fragmented, and difficult to automate.

In fact, one study found that automated, or “zero‑touch,” IoT provisioning was roughly 2.5 times faster than expert manual workflows, and nearly 9.3 times faster than non-expert efforts, highlighting how manual processes don’t hold up at scale.

Today’s teams need real-time control over connectivity. Whether managing IoT devices, consumer electronics, or mobile-enabled products, they expect to activate, update, and switch SIM profiles without relying on physical hardware or juggling multiple carrier portals.

That’s where eSIM management platforms come in. These platforms offer a centralized solution for remotely deploying and managing embedded SIM profiles at scale, thereby eliminating the need for manual swaps and carrier lock-in.

In this post, we’ll explain how eSIM management platforms work, walk through practical use cases, and show you what to look for when choosing a solution to scale connectivity more efficiently.

What is an eSIM management platform?

An eSIM management platform lets you remotely manage SIM profiles embedded in connected devices. It supports the full eSIM lifecycle: provisioning, activation, switching, deactivation, and deletion.

Unlike traditional SIM cards, eSIMs can hold multiple operator profiles. While this flexibility is powerful, it also introduces complexity. Without a centralized platform, switching between profiles or updating configurations at scale becomes nearly impossible. A proper management layer is essential.

eSIM management platforms are widely used by IoT solution providers, MVNOs (Mobile Virtual Network Operators), enterprises managing global fleets, and OEMs (Original Equipment Manufacturers) that embed mobile connectivity in devices such as tablets, wearables, or industrial sensors.

They offer a programmatic interface to functions that would otherwise require manual carrier coordination, addressing the pain points of manual SIM provisioning and fragmented carrier portals.

Why legacy provisioning can't keep up

The traditional model for provisioning SIM cards relies on physical inventory. Devices need to be shipped with a SIM already inserted, or they require manual handling before deployment. Every update, replacement, or migration introduces friction.

Carrier portals complicate matters further. Most offer limited visibility into SIM usage, don't support bulk actions, and can't be easily integrated into internal workflows. Managing devices across different countries or carriers means juggling multiple interfaces with inconsistent functionality.

Even for enterprises with in-house tools, provisioning SIMs typically involves direct carrier integrations, which are time-consuming and hard to scale. The lack of standardization across carriers makes automation challenging, resulting in increased operational overhead with each new deployment.

For organizations managing thousands of devices or preparing to scale, this traditional approach becomes a blocker. Staying ahead means preparing for the future of IoT connectivity, where scale, automation, and resilience are non-negotiable.

What to look for in an eSIM management platform

A reliable eSIM platform should support remote provisioning that's compliant with GSMA standards, specifically SM-DP+ and SM-SR. This compliance ensures compatibility with eSIM-capable devices and enables the management of profiles over the air.

You should be able to download, update, or delete SIM profiles without needing physical access to the device. This capability is the core value of eSIM: managing connectivity without shipping a technician or issuing a new card.

Integration should be a priority. Role-based access and full API support are essential for automation and team management. You should be able to assign roles, trigger actions programmatically, and monitor status in real-time—all from your dashboard or applications.

A quality platform also integrates with your existing connectivity stack. This integration includes visibility into usage data, alerts for changes in behavior, and integration with billing and analytics systems. For developers, extensive documentation and a reliable SDK enable the direct embedding of connectivity management into firmware, apps, or internal tools.

Support for both consumer and machine-to-machine (M2M) eSIM form factors is crucial. Whether you're building wearable devices, deploying industrial sensors, or provisioning tablets, you need to manage a variety of hardware profiles without limitations.

Real-world use cases for eSIM management

An eSIM management platform provides centralized control over connectivity, enabling flexibility to scale across industries, adapt to changing needs, and streamline operations globally.

Industrial and field deployments

IoT deployments in the field, such as industrial sensors, smart meters, or utility infrastructure, benefit from eSIM management by eliminating the need for site visits when SIM configurations are changed. You can push updates, switch profiles, and troubleshoot remotely without interrupting service or dispatching a technician. This minimizes downtime and simplifies operations in hard-to-reach environments.

Remote healthcare and critical devices

For healthcare devices in remote clinics, home monitoring setups, or mobile medical units, eSIM platforms ensure continuous, reliable connectivity. If a network becomes unreliable or a profile needs to be updated, teams can push changes over the air. That means no service interruptions, better patient care, and no need for physical intervention.

Global device fleets

Devices that cross borders—such as logistics trackers, connected vehicles, or smart point-of-sale systems—benefit from dynamic profile switching. Instead of relying on expensive international roaming agreements, you can switch to local carrier profiles as needed. This improves performance, reduces costs, and ensures consistent connectivity across regions.

Consumer electronics and MVNO onboarding

Remote SIM management streamlines the activation process for mobile-first devices, including smartphones, tablets, and wearables. MVNOs, companies that provide cellular service without owning their own network infrastructure, can activate users directly on their own profiles, eliminating the need for physical SIM cards and reliance on third-party carriers. eSIMs also enable seamless dual-SIM functionality, letting users manage multiple profiles from a single device.

OEM manufacturing and device provisioning

OEMs, companies that design and manufacture connected devices, such as wearables, tablets, or industrial sensors, can embed and configure eSIM profiles during the production process. This enables zero-touch provisioning, so devices connect automatically when powered on. It also accelerates global rollout by giving OEMs control over how and where devices connect after they leave the factory.

Take control of eSIM connectivity at scale

The shift to eSIM is no longer optional for teams managing global devices—it’s essential. Physical SIMs and carrier-specific tools weren’t built for real-time, programmatic control. As connected fleets grow, these legacy systems create more friction than flexibility.
