How Entitlement Servers Unlock New Services and Revenue for MNOs

In this article we’re providing a quick digest of the Entitlement Servers’ (ES) crucial role in Mobile Network Operators’ business structures. We’ll look at how ES drive the next generation of mobile services and how expert partners like 1GLOBAL are providing the tools that make this essential transformation possible. 

Mobile Network Operators (MNO) operate in a busy field. The same technologies that have lowered the cost of entry also guarantee vigorous competition, and the sophistication of network hardware now means that simply having reliable network uptime is no longer a noteworthy differentiator.  

The competitive edge has shifted from the olden days of having more reception bars than your competitor to providing service innovation, engaging customer experiences, and offering value-add via a supporting digital ecosystem.  

When customers have the ability to switch service providers almost instantly, the ability to rapidly deploy, manage, and monetize new services is no longer a competitive advantage but a baseline requirement for operation.  

A mistake that many short-lived MNOs make is to assume this is a branding and marketing challenge. The most successful operators are the ones that understand the solution depends on a critical, yet intentionally low-profile, piece of network infrastructure called the Entitlement Server. 

What are Entitlement Servers? 

This platform is the unsung hero of virtually all new network subscriber interactions. It orchestrates the ‘magic’ activation of features and services first leveraged by Apple and now expected as standard.  

It automates the deeply complex interaction between network hardware and an MNO's service portfolio, delivering working features to user's devices. 

Deploying a modern, compliant Entitlement Server is not a tactical option but an operational necessity for any forward-looking MNO. It is the keystone that supports not only advanced services and a superior user experience, but also diversified revenue streams, essential operational efficiencies, robust security controls, and entry into the disruptive and highly profitable Embedded Telco market.  

How do Entitlement Servers work? 

At its core, an Entitlement Server (ES) is a network component that manages device and service permissions. It functions as a centralized policy and orchestration hub, controlling which features are enabled on which devices for which subscribers.  

The primary function of an ES is to ensure that mobile devices automatically get the necessary config for carrier services. These services include everything from Smartwatch pairing to Voice over LTE (VoLTE), Wi-Fi Calling (VoWiFi) and 5G access.  

Before ES took over, the activation of these features was tediously manual and aggravatingly error-prone, resulting in a poor user experience and high support costs. 

Where ES really add value is through their role as gatekeeper, sitting between the MNO's architecture and external systems, acting as a single authoritative entitlement decision-maker. 

Roles of Entitlement Server 

The server cross-references with the MNO’s Business Support Systems (BSS). This is a critical step to verify a customer’s subscription plan, check their permissions, and confirm that they’re authorized to use the requested service. 

ES coordinate with Authentication, Authorization and Accounting (AAA) servers to ensure that requests are authentic, typically using robust SIM-based security like Extensible Authentication Protocol-Authentication and Key Agreement (EAP-AKA) to prevent fraud. 

For interactive processes, ES leverage Websheet Servers. This component effectively formats miniature web pages directly on the device's screen, allowing the MNO to present essential communication such as T&Cs, plan offers, or activation flow without requiring the install of a separate app, such as a browser. 

All of these orchestrations happen within a complex and sometimes overlapping environment of technical standards. A modern ES must be fully compliant not only with GSMA specifications, such as TS.43, but also with a variety of vendor-specific protocols from Apple, Google, Samsung etc. Managing these disparate and constantly evolving standards is a significant challenge for MNOs and highlights the value of ES automation. 

This way, ES provide invaluable insulation for MNOs, shielding them from the immense technical complexity of the global device and standards ecosystem. An MNO seeking to support the full range of modern devices would otherwise need to build, certify, and maintain separate, complex integrations for GSMA, Apple, and Android ecosystems, while also connecting them to their own unique backends. All this, while still tending to the daily core business too.   

A little over a decade ago, the manual approach was already becoming prohibitively expensive. It was slow and resource-intensive, creating a major barrier to innovation. ES, particularly when delivered as a cloud-native ‘as-a-service’ platform by a specialist connectivity partner like 1GLOBAL, consolidates and automates integration.  

It provides a unified API-based interface for the MNO's core systems while handling all the device-specific protocol negotiations on the other side. This dramatically reduces the MNO's internal development overheads, and radically accelerates time-to-market for new devices and services, transforming daunting integration problems into streamlined launches.  

Enabling Premium Services 

Thanks in large part to the efficacy of ES, the hallmark of the modern smart-device experience is getting access to premium services easily and almost instantly. This frictionless experience was, for a while, an enormously powerful competitive differentiator when getting a new Apple phone, but is now the baseline expectation for all consumers. 

This same sense of ‘magic’ activation experience now applies to a much wider range of premium services that are essential for a modern MNO's portfolio: 

• VoLTE & VoWi-Fi 
  The ES checks if a subscriber is authorized and, if so, automatically pushes the correct config to the device, enabling high-definition voice calls over the 4G/5G network and seamless call continuity over Wi-Fi in areas with poor cell reception. For many modern devices and services, entitlement-based activation of VoWi-Fi is mandatory. 

• Tethering & hotspots 
  The ES acts as the gatekeeper for the mobile hotspot feature. It allows the MNO to dynamically enable or disable tethering based on the subscriber's data plan, preventing unauthorized usage and creating opportunities for upselling to plans with more generous hotspot allowances. 

• eSIM transfer 
  The ES facilitates the seamless transfer of a subscription from a physical SIM to an eSIM, or from an old device to a new one. This is a critical feature for ensuring customer retention during the device upgrade cycle, which can be a major point of customer churn. 

• Dual SIM 

  The ES is also central to managing subscriptions on multiple devices. Where new eSIM-enabled devices are purchased and paired with a smartphone – think an Apple or Android smartwatch – the ES verifies the user’s entitlement and handles the coordination of plan activation on the wearable device. This complete synchronization between devices enables additional monetization opportunities for MNOs offering data or voice plans on supported smartwatches that are tied to the user’s main subscription. 

The ES paradigm shift means the MNO now operate with a flexible service catalog rather than a simple menu of differently sized plans. Customer subscriptions evolve from monolithic blocks into modular, flexible containers that open the door to new offerings and reward agile business models. 

Revenue growth through expanded offering 

The ES is the MNO's ideal tool to grow beyond simple flat-rate data packages and create sophisticated, multi-layered revenue models that continually reinforce value. It enables precise customer segmentation and the monetization of diverse value-add services. 

The most obvious way to get more value from a customer is to offer to sell them more of what they want. With ES, an MNO can implement and automate distinct tiers that appeal to different customer segments.  

A basic plan might include standard 5G data and voice, while premium can be enhanced with VoWi-Fi, while premium+ comes with smartwatch connectivity for the whole family. The ES is the enforcement point for these tiers. When a device checks in, the ES queries the BSS and enables only the specific set of features that the customer has paid for. 

Beyond tiered plans, the ES enables a granular pay-per-feature model, creating new finely targeted revenue streams with add-on services.  These monetization strategies have a clearly measurable impact on an MNO's Average Revenue Per User (ARPU) and customer churn.  

One of the hardest bottlenecks to overcome in a fully electronic marketplace can be in educating customers about what they’re missing. Digital sales have always lacked the advantages of a physical shop to show off what the premium products can offer. This is an issue that ES-powered, finely tiered plans can overcome by creating clear ‘upgrade paths’ for customers, encouraging them to move up to higher-ARPU brackets.  

For example, mobile tethering can be offered with limited access on basic plans, expanded access on regular plans, and unlimited access on premium tiers  – driving upgrades to higher-value plans and increasing ARPU.  

Even services that initially seemed detrimental to the MNO can now be effectively monetized.  

At one point, WhatsApp and other dialing apps seemed like they’d destroy the whole concept of MNOs. Now VoWi-Fi, which can’t be directly billed by the minute, still contributes to long-term ARPU growth. By including them in premium service tiers, MNOs can justify the higher price of those tiers while enhancing core service quality, which in turn reduces churn.  

The ES significantly enhances customer ‘stickiness’ by deeply embedding the MNO's services into the user's digital life. A customer with their smartphone, smartwatch, tablet, and laptop all seamlessly integrated into a single MNO's network is far less likely to undertake the hassle of switching providers.  

The seamless eSIM transfer feature is particularly critical in this regard, and has been an absolute keystone in making Apple the telco titan it is today. While not a directly monetized feature, by making the device upgrade process effortless and allowing users to move their subscription to a new phone with a few taps, the ES removes a major point of friction where customers have historically been most tempted to jump ship. 

Wearables and more 

ES enables MNOs to expand their service footprint beyond smartphones and build an engaging, multi-device ecosystem around a single subscriber.  

This strategy is crucial for growth, as it increases the number of paid connections per subscriber and enhances customer engagement and loyalty. The ES handles the complexity of adding various different device types to a user's plan, making the process simple for the customer and transparent for the MNO. 

Two primary use cases dominate the wearables space, both facilitated by ES: 

• Shared Number 
  Branded as OneNumber by Apple and Shared Number by Samsung, this is where a smartwatch shares the same number as the primary smartphone. The ES is responsible for the complex backend that ensures when a call comes in, it rings on both devices. It also enables the watch to make calls and send messages using the primary number, even when the phone is out of direct connection range. This capability is a powerful driver for the adoption of paid wearables plans. 

• Standalone Number  
  Often sold as ‘family’ plans, ES supports scenarios where a companion device is provisioned with its own, separate number but is managed from the primary account holder's phone. This is the foundation of Apple's Family Setup feature, which allows a subscriber to provide a wearable device connection for a relative who doesn’t have their own phone, effectively opening up an entirely new customer segment. 

Consumers have access to a constantly broadening catalogue of smart devices to enhance their digital lifestyle, but more devices also mean more connections to be made and more setup procedures to follow. 

Without a fully effortless provisioning system, a less sophisticated user will simply not bother activating cellular on all of their devices, while the more sophisticated ones will seek out specialist cheaper providers for their specific data plans.  

ES makes adding a new device to an existing plan a simple, on-device, one-tap process. This convenience creates a powerful incentive for customers to consolidate all their device connectivity with their primary MNO.  

As the number of personal connected devices per person continues to grow, the MNOs that provide the path of least resistance will be the ones that capture the largest market share and maximize the total lifetime value of every subscriber. 

Smartwatch activation: ES vs QR Code 

While QR code–based activation is still used for pairing smartwatches with mobile devices, it is increasingly seen as an outdated and inconvenient process. Mobile operators are now moving toward ES technology, which provides a smoother and more customer-friendly activation experience. 

Compliance & control 

Beyond its role as a persuasive upseller, ES are critical network gatekeepers. They function as a powerful security and compliance checkpoint, protecting both the subscriber and the MNO's network from intrusion and misuse. 

Before connecting any service, ES will perform a series of checks to ensure the validity of the request.  

To look out for stolen devices, the server can cross-check with the network's Equipment Identity Register (EIR) for the connecting device's unique International Mobile Equipment Identity (IMEI) number. If that number is blacklisted as lost or stolen, the ES can immediately block service.  

Meanwhile, the ES also performs similar checks for subscriber validation, verifying that the profile is legitimate and authorized. This process is crucial for preventing stolen SIM cards or a cloned device fraudulently gaining access to services.  

An ES security posture moves an MNO beyond dated techniques like SMS-based One-Time Passwords (OTPs), which are vulnerable to phishing, social engineering, and SIM-swapping.  

Instead, a sophisticated ES utilizes ‘silent authentication’ through secure protocols like EAP-AKA to counter SIM swap and hijacking.  

With the ES capability for granularity, it will also filter connections that are prohibited or insecure based on context, such as the user's geographic region, specific hardware, or suspicious usage patterns, thus enforcing policy and jurisdictional violations.  

This capability is vital for ensuring legal compliance. For regulations that require Know Your Customer (KYC) verification, the ES can trigger a websheet flow to securely collect ID documents or obtain explicit consent before any service is activated, creating a documented compliance trail. 

Next Steps  

The emergent generation of mobile services are not being defined by the raw speed of their network (although 5G is certainly helping) but by the scalability and intelligence of the platforms that orchestrate it. ES have evolved from niche technical component into the strategic, revenue-generating cornerstone of modern Mobile Network Operator strategy.  

They bridge the gap between an MNO's service portfolio and the customer’s device, enabling the near-instant digital gratification that customers demand. Securing a comprehensive cloud-native Entitlement Server solution, particularly through an expert partner like 1GLOBAL, is easily among the most critical steps an operator can take to maintain viability.
