TL;DR / At-a-Glance Summary
The Limit of eSIM
eSIM removes the need for physical SIM cards but does not solve the complexity of multi-carrier management at a global scale without a central control layer.
Why RSP Aggregation Matters
RSP aggregation unifies multiple carrier provisioning systems into one control plane so enterprises can manage connectivity centrally. This reduces engineering overhead and accelerates deployment timelines.
The Role of SGP.32 in IoT
SGP.32 enables push based provisioning for headless IoT devices so profiles can be installed and switched over the air without user interaction. This is essential for large scale deployments with long lifecycles.
Business Benefits of Aggregation
With aggregation you get global SKU simplification, automated fallback for resilience, and lower operational cost through policy driven control. Connectivity becomes programmable and more efficient.
Spenza Makes Aggregation Practical
Spenza provides a unified API, SGP.32 native orchestration, policy based automation, and operator neutral BYON support so enterprises can implement multi network eSIM deployments at scale.
Managing a global IoT fleet has traditionally meant managing growing complexity. As enterprises expanded across regions, they were forced to juggle multiple Mobile Network Operator MNO relationships, each with its own commercial terms, technical integrations, and Remote SIM Provisioning (RSP) platforms. Every carrier introduced different APIs, profile formats, onboarding timelines, and operational constraints, making global scale synonymous with integration overhead.
By 2026, this approach is no longer sustainable.
The industry is shifting from a model built on integration to one driven by aggregation. Rather than connecting enterprise systems to numerous carrier backends, modern organizations deploy multi-network eSIM profiles through a single RSP aggregation platform. This allows global connectivity to be managed as a software-defined utility instead of fragmented telecom infrastructure.
This blog explains what RSP aggregation is, how modern deployments operate under the latest GSMA standards, and why aggregation has become a must-have architecture for global IoT and enterprise connectivity. It also shows how Spenza functions as the orchestration layer that makes this model practical and scalable in real-world deployments.
From Integration Debt to Aggregation Thinking
The Old Model: Built on Carrier Integrations
For years, deploying eSIM connectivity across multiple carriers required enterprises to integrate directly with each operator’s RSP infrastructure. Each new carrier relationship meant building and maintaining a separate technical and operational connection.
For example, supporting three carriers typically required:
- Three separate SM-DP+ servers
- Three different API schemas
- Three onboarding and certification processes
- Three billing, reporting, and reconciliation models
As deployments expanded across regions, roaming partners, and device variants, this approach created what many teams now recognize as integration debt.
How Integration Debt Compounds at Scale
Every additional carrier increased:
- Engineering effort to build and maintain integrations
- Testing complexity across devices and regions
- Operational risk from inconsistent workflows
- Long-term maintenance costs tied to versioning and upgrades
For large IoT fleets with tens of thousands or millions of devices, this complexity was not just inconvenient. It was structural.
Direct carrier integrations were never designed to be replicated, versioned, and maintained at global scale. Each new operator added friction not only during initial deployment, but throughout the entire device lifecycle.
Why Aggregation Became Necessary
Solving this problem required a different architectural approach. Instead of embedding carrier specific logic into enterprise systems, leading organizations moved toward a single standardized control layer.
This shift from integration to aggregation removes carrier complexity from device and application teams, centralizes provisioning and lifecycle control, and enables global eSIM deployments to scale without multiplying operational burden.
What Is RSP Aggregation and What Does It Really Solve?
An RSP aggregation platform acts as a centralized control layer between your devices and the mobile network operators providing connectivity. Instead of integrating directly with each carrier’s subscription management system, enterprises connect to a single platform that manages all carrier relationships on their behalf.
At its core, RSP aggregation delivers three essential functions:
1. Aggregation and Marketplace
The platform consolidates wholesale connectivity plans and eSIM profiles from multiple MNOs into a single, unified catalog. Many platforms also simplify billing, offering a single invoice for multi-carrier deployments.
2. Orchestration and Policy Control
RSP aggregation determines which carrier profile a device should receive based on geography, cost, quality of service, or failover rules. It also manages over-the-air lifecycle events, including activation, switching, suspension, and decommissioning.
3. Management and Analytics
The platform provides a single pane of glass for device inventory, usage, spend, alerts, and diagnostics. Integration with telecom expense management and billing systems ensures operational efficiency and visibility across the fleet.
How RSP Aggregation Works Technically
Think of it as a multi-carrier control plane for eSIMs. It understands carrier-specific profile formats, regulatory requirements, and operational processes, keeping devices connected, secure, and compliant throughout their lifecycle.
Technically, an RSP aggregation platform:
- Integrates with multiple carrier SM-DP+ backends
- Operates as a unified eSIM IoT Manager (eIM) under the GSMA SGP.32 standard
- Exposes a single, consistent API to enterprise systems
- Orchestrates profile selection, secure delivery, switching, and retirement
- Abstracts carrier-specific complexity away from device and application teams
This architecture allows enterprises to scale multi-network eSIM deployments without increasing operational burden, making global IoT connectivity faster, simpler, and more reliable.
RSP Aggregation vs Single-Vendor RSP
Not all eSIM solutions are created equal. Choosing between a single-vendor RSP and a full RSP aggregation platform can have a major impact on scalability, cost, and operational efficiency.
| Capability | Single-Vendor RSP (one MNO) | RSP Aggregation Platform |
|---|---|---|
| Carrier Choice | Locked to the host MNO | Mix and match multiple MNOs for maximum flexibility |
| Failover and Optimization | Limited | Automated carrier switching based on rules and policies |
| Global Coverage | Depends on the host MNO | High, leveraging the collective coverage of multiple operators |
| Procurement and Billing | Multiple contracts required for multi-carrier setups | Consolidated marketplace with a single bill option |
| Time to Scale | Longer due to per-operator integration | Faster thanks to centralized integrations |
RSP aggregation platforms combine the flexibility of many carriers with the operational simplicity enterprises need. By centralizing orchestration, policy control, and lifecycle management, aggregation transforms connectivity from a fragmented set of contracts into a scalable, software-driven platform.
Why RSP Aggregation Matters in 2026
By now, enterprises expect IT infrastructure to behave like cloud services: programmable, flexible, policy-driven, and observable. Connectivity should be no different.
Yet many teams still treat networks as fixed artifacts — decided at manufacture and never changed. That approach is costly and brittle:
- Devices shipped with a single carrier may underperform in parts of the world where that carrier is weak.
- Legacy roaming frameworks can violate local regulatory requirements in places like Brazil or India.
- Manual switching and contract renegotiations slow product launches and inflate operating costs.
The right orchestration layer changes this. RSP aggregation makes connectivity:
- programmable — carrier decisions are policy-driven, not hardcoded,
- adaptive — profiles can change as conditions evolve,
- vendor-neutral — no lock-in to one operator,
- replaceable over the air — no physical SIM swaps.
An MVNO resells connectivity under a single commercial model, whereas an RSP aggregation platform orchestrates multiple carrier relationships, profiles, and policies without owning or reselling the network itself.
SGP.32: The Foundation for Scalable IoT eSIM
Key to modern IoT deployments is the GSMA’s SGP.32 standard, which was built specifically for unattended devices like sensors, meters, and industrial endpoints. Under SGP.32:
- Devices start with a lightweight bootstrap profile just to get online.
- They connect to a centralized orchestration platform (called an eIM).
- That platform selects and pushes the right carrier profile OTA.
- Over time, profiles can switch as policies or conditions change — without truck rolls or user interaction.
This zero-touch provisioning model is the only practical way to deploy millions of devices globally and manage them through a full lifecycle.
- Your devices support eUICC and a compliant IoT Profile Assistant (IPA)
- A global bootstrap profile is available, even at low bandwidth
- Your orchestration layer can act as an SGP.32-compliant eIM
- Profile switching policies are defined before large-scale rollout
What Aggregation Enables in Practice
The SGP.32 push model demonstrates how provisioning works. Aggregation, however, determines whether connectivity can scale, transforming it from a limitation into a strategic capability for global IoT deployments in 2026.
1. One Hardware SKU with Global Connectivity
Manufacturers no longer need region-specific SIM variants. One device and one global eSIM are enough, while carrier selection can be deferred until deployment or even years later. This approach reduces inventory complexity and accelerates time to market.
2. Built-In Resilience and Cost Control
Carrier outages or price changes no longer require manual intervention. With smart policies:
- Devices automatically switch to preferred networks
- Cost thresholds trigger plan changes
- Fallback logic protects uptime without manual oversight
3. Elimination of Unnecessary Markups
Many aggregation platforms support Bring Your Own Network (BYON) models. Enterprises can maintain direct carrier contracts and avoid reseller markups. This transparency reduces effective costs and preserves commercial leverage over time.
4. Simplified Operations at Scale
As fleets grow, managing multiple carrier portals, fragmented invoices, and manual audits becomes expensive. Aggregation platforms provide a single pane of glass, unified reporting, and policy-based automation.
Analyst research from Gartner indicates enterprises can waste 20 to 30 percent of wireless spend due to unused subscriptions and billing errors. RSP aggregation platforms reduce audit effort by 50 percent or more by combining orchestration with centralized analytics. The real value lies in a platform’s ability to automate, optimize, and scale connectivity across global fleets, not just basic RSP enablement.
Reality: The real value appears over time through lifecycle control, continuous optimization, and policy-driven switching.
