eSIM technology replaces traditional SIM technology residing in card form factor with a built in software/hardware solution which enables remote SIM provisioning capability. Also provides extra functionality while decreasing friction points on customer touching channels. eSIM technology mainly brings the aforementioned capability on two segments
Consumer segment is directly aimed to bring eSIM technology to the end users. Consumer devices are provisioned with eSIM technology in operators of their choice. There are variety of devices falling in this category including but not limited to wearables, smart phones and tablets.
The provisioning process requires consumer involvement in the provision lifecycle to be able to subscribe to the operator and then download eSIM profile to the device possessed by the consumer even without a need to visit the dealers. Once profile is enabled by the operator, the consumer gains access to the services provided by the operator.
• Seamless subscription lifecycle
• Easy to migrate to another MNO
• On boarding is initiated on screen with some prompts. And provision is completed over the air.
• Consumers can switch network without physically changing the SIM
• eSIM is not removable hence won’t be damaged, not effected from vibration, and stable at high temperatures.
• Thanks to small eSIM size in device, manufacturers are more free to decrease device sizes
Rather than putting up with the limitations of generic devices, organizations can employ inexpensive connected devices designed for specific tasks, or even specific products.
The total cost of ownership of devices (covering provisioning, product tracking, and procurement arrangements) is reduced.
Not removable esim won’t be damage, not effected vibration, and stable at high temperature.
eSIM extends the reach of the secure facilities from specific physical locations, to any location where the device can be reached over the internet. eSIM protocols provide security and integrity for data transfer.
eSIM utilizes GSMA framework to comply world class transaction and platform security in every layer. It provides seamless provision life cycle along with world wide interoperability. End users in consumer side only needs to go through simple steps to activate their devices while in M2M side even there is no user intervention required. Consumer interaction with operators is minimized yet covers all scenarios of receiving service from operators with an effective way. With respect to roaming scenarios, new use cases ease life of consumers where they can remotely arrange their subscriptions wherever possible.
DP is the entity which operators use to securely encrypt their operator credentials ready for over the air installation within the SIM. The SM-DP is responsible for preparing, storing and protecting operator Profiles (including the operator credentials). It also downloads and install Profiles on to the eUICC.
SM-DP+ is responsible for the creation, download, remote management (enable, disable, update, delete) and the protection of operator credentials (the Profile). It is given the + designation as it encapsulates the functions of both the SM-DP and the SM-SR of the M2M solution.
The SM-SR is responsible for managing the status of Profiles on the eUICC (enable, disable, delete). It also secures the communications link between the eUICC and SM-DP for the delivery of operator Profiles.
