eSIM - Let’s talk business
eSIM technology by Ericsson will also able convenience for the consumer and growth for Service Providers.
eSIM is described as an embedded universal integrated circuit card (eUICC) defined by GSMA, the global association responsible for setting the overall telecommunication framework with approximately 800 mobile operators. Compared to legacy plastic SIM cards that are removable, the eUICC can be soldered directly into the device. With the evolution of the eSIM/eUICC, it has been physically improved to be able to fit extreme environments like temperature, humidity, vibration and water-resistant.
One of the key requirements is that eSIMs must adhere to the same security specifications as current SIMs.
One of the great benefits eSIM brings to consumers, Communications Service Providers (CSPs) and enterprises, is flexibility. As a key component of connectivity services, eSIM makes the selection, contracting, and onboarding of CSPs easier. Consumers do not need to look for CSPs and go to CSP shops to buy SIM cards.
eSIM consumers and enterprises can continue to enjoy all legacy SIM services such as roaming services, local breakout services, or SIM applets with multi-International Mobile Subscriber Identity (IMSI) services when and where applicable. As a key innovation, eSIM can trigger a localization service with the flexibility to choose a new local CSP to remotely provision and activate a new subscription to the device when needed, over the air.
This flexibility truly enables global device manufacturers to rely on a single global eSIM to be able to connect all their devices all over the world. eSIM technology simplifies device manufacturing and logistics by enabling a single stock-keeping unit. Another benefit is guaranteed seamless global connectivity services provided by CSPs across the entire device life cycle.
How the eSIM technology works
Ericsson’s eSIM solution is comprised of Ericsson Secure Entitlement Server (SES) and Ericsson eSIM manager (GSMA certified SM-DP+) serving the onboarding of eSIM consumer devices and creation of eSIM profiles.
Ericsson’s eSIM technology provides a fully automated end-to-end device and subscription orchestration procedure. Ericsson’s eSIM solution manage the device detection and user authorization for onboarding the eSIM device. Onboarding a device involves creation of user and subscription profile, eSIM Profile, provisioning handling of both eSIM device and network elements as well as updating the Service Provider’s back office system as relevant.
It contributes with simplified user experience process for end users and, at the same time for the Service Provider, saving operational expenses for handling eSIM devices over their life cycle management.
Ericsson’s eSIM solution will give the Service Provider the opportunity to launch many attractive services for a wide range of eSIM devices. Users can instantly enable new services by downloading a new eSIM profile to their new eSIM device with minimum efforts.
The need to pre provision, create batch processes or use middleware solutions for eSIM profiles, is removed. The simplicity of Ericsson’s eSIM technology (activation) will give Service Providers the possibility to quickly launch new and innovative use cases improving top line.
Ericsson Secure Entitlement Server
The Ericsson Secure Entitlement Server supports the onboarding of VoLTE and Wi-Fi calling for SIM and eSIM devices as well as packet data eSIM devices. It handles multiple authentication channels and the orchestration of subscription profiles in network elements.
