The adoption of eSIM technology improves connectivity between smartphones and wearables, leading to increased market demands for these innovative services.

With these benefits, an entitlement server becomes the strategic control point that turns complex device provisioning into a competitive advantage—boosting ARPU, cutting OPEX, and delighting subscribers across consumer and IoT segments.












An Entitlement Server (ES) is a specialized component in a telecom network that verifies whether a device and user are eligible to activate a particular service — and then orchestrates the configuration process to make it happen.
An Entitlement Server (ES) acts as a control gateway between the mobile network and connected devices. It authenticates both the subscriber and the device, then delivers over-the-air (OTA) permissions and configuration settings required for premium services to work instantly — such as eSIM activation, VoLTE, VoWiFi, Multi-SIM (e.g., smartwatches), RCS, and eSIM Transfer. By serving as a central gateway, the ES prevents various device types from connecting directly to the operator’s BSS/OSS systems, ensuring consistent service control and security across different platforms. Additionally, the ES manages the activation and lifecycle of these feature services through the device’s native user interface, offering a seamless user experience.
The Entitlement Server enables subscribers to self-register eSIM-based multi-device services directly on their smart devices, offering zero-wait, one-touch activation. This not only significantly reduces operational costs for carriers but also enhances user experience and drives customer loyalty.
It is not always possible to get a carrier agreement with an OEM within the timeframe required. Redtea offers an alternative whereby specific ES features can be implemented without the need for a carrier agreement. Interested? Contact us for more information on how we can support you.
Yes, Redtea supports Apple, Samsung and other Android devices compliant with the Apple, Samsung and GSMA TS.43 specifications but also supports entitlement for other OEMs that do not comply with the GSMA TS.43 specifications.
Yes, you can. We offer two implementation models: on-premise and SaaS. With the on-premise deployment model, we implement the Entitlement Server on your infrastructure or Private Cloud. It is also possible to implement it in the Public Cloud. We also offer a SaaS model where the Entitlement Server is offered as a service.
