Estimates suggest the global eSIM market could reach between $14 billion and $21.24 billion by 2027 to 2032, with increasing adoption of IoT devices across various sectors being a significant driver of this growth (Grandview research). 

As market competition increases eSIM platform and application providers need to find ways to differentiate their services and look beyond the current largest use case of travel. Stacuity delivers a flexible, software-defined mobile core, which is independent of third-party vendors. Our solution enables seamless global coverage, optimised services and complete control over connectivity, providing businesses with the tools to generate new and existing revenues from B2C and B2B enterprise customers.

The benefits of an eSIM

An eSIM (embedded SIM) is a small, rewritable chip built into devices like smartphones and laptops that allows mobile services to be provisioned remotely, without the need for a physical SIM card.

For enterprises the capabilities of an eSIM, combined with an advanced solution such as Stacuity’s Core Network delivers;

  • Centralised provisioning and management
  • Seamless connectivity across multiple network providers
  • Enhanced data security and compliance
  • Rapid deployment
  • Flexible roaming and multi-network resilience

How the Stacuity platform supports eSIM solution providers

By leveraging our solution, eSIM providers strategically retain operator relationships (and all connectivity margins), whilst gaining access to a cost-effective core, simplifying the orchestration of global operator IMSIs. Additionally through operating their own Core, providers gain the ability to differentiate their service proposition with unique capabilities and features.

A unified proposition

Providing customers with a unified proposition whilst managing IMSI integrations from multiple mobile operators becomes easy with Stacuity. By operating their own mobile core platform, providers can seamlessly integrate, manage and optimise upstream partners and vendors. 

With the Stacuity portal (or via our full-feature API), you can consolidate IMSIs from various MNOs into unified ranges simplifying their operations and improving customer experience, removing the dependency on end-users having to download or undertake additional functionality. It is all controlled via the core and your back end applications. This also enables providers to offer tailored pricing and service plans to customers in different regions, optimising revenues.

Advanced features for eSIM differentiation

Stacuity’s advanced core network features allow providers to create their bespoke offerings to attract new markets, for example B2B. All the below features are self-servable view a full-featured API or the Stacuity portal.

  • Dynamic Quality of Service (QoS) with real-time rate limiting: Providers can dynamically adjust speed and bandwidth tiers in real-time, offering everything from basic to premium service levels. Enables tiered pricing models and the ability to upsell customers based on their needs. Creates premium offerings for demanding users (e.g., B2B with critical application needs)

  • Content controls: Providers can self-route traffic through filtering platforms to create secure, family-friendly, or enterprise-compliant environments. This allows for integration with third-party filtering services. Providers can offer this capability as a value added service, for example parental control bundles or secure browsing solutions for businesses.

  • Site restrictions: When a customer’s data allowance is depleted, providers can limit access to non-essential sites while keeping critical services (like top-up portals) accessible. This enforces fair usage policies without completely cutting off connectivity.

  • Efficient traffic pooling: Allows the sharing of data allowances across multiple eSIMs within a single account (e.g., business fleets or family plans). This attracts multi-user accounts by offering cost-effective and flexible data management solutions. Increases overall data consumption and stickiness.

  • Location-based services: Leveraging location data, providers can offer analytics, tailored content, and improve customer experience. This creates opportunities for targeted marketing, personalised service offerings, and data-driven insights into customer behaviour and network usage.

  • Local breakout: utilising our distributed edge network capabilities enables the provider to retain the end users traffic within the region – reducing latency and offering the ability to onboard local IMSI partners to reduce roaming costs and optimise margins for the providers. 

    In addition, utilising our edge capabilities, providers can ensure consistent performance regardless of their location. Users will also experience smoother browsing, faster application performance, and reliable connectivity, eliminating the frustrations often associated with international roaming.

Network Control

eSIM providers gain advanced and flexible network control through Stacuity’s network steering capabilities. You can route traffic to preferred networks based on various factors such as cost, quality of service, or specific service requirements. This ensures optimal network utilisation and cost efficiency.

Stacuity’s architecture allows for the simultaneous use of multiple networks. This provides inherent redundancy, ensuring continuous connectivity even if one network experiences issues. Providers have the autonomy to select their preferred network backups.

Expanded Reach

Whilst we offer a bring your own IMSI option, providers also have the flexibility to tap into Stacuity’s global MNO partnerships for additional IMSIs and data bundles, offering more competitive pricing to your customers.
