Difference between M2M and Consumer In addition to architectural differences, which will be discussed later, the main difference between M2M and Consumer is the right to change subscription. Consumer: Consumer has the full right to order, activate, delete,..etc profiles The device usually does not come with a preinstalled bootstrap profile Profile installed in 30 seconds or less Profile download can be done using any IP based communication (e.g, WiFi, Mobile Network,..etc) Wearables M2M: Only OEM or (its representative) has the right to order, activate, delete,..etc profiles Device comes with a pre-installed bootstrap profile Profile installation takes minutes to hours Profile download can be done only using a Mobile Network Cars Tablets and smartphones Smart Metering Devices Laptops Others (PoS and Medical Devices)
What is an Embedded SIM (esim) esim or euicc is a programmable SIM that can be seamlessly and securely provisioned over the air. Enabler for faster deployment and adoption of Internet of Thing (IoT) Facilitates easy switch between MNOs, allowing consumers to select the MNO that offers best deal esim can be removable or soldered into the device at time of manufacturing (*) (*) Not all devices must use embedded SIMs. Most M2M devices will use esim. Some consumer electronics might have removable but reprogrammable SIMs. This may prove a transition solution, allowing the ecosystem to move smoothly from the current traditional removable SIM to embedded SIMs without major changes in mobile network operators operations.
Why Introducing esim The key driver for the introduction of esim technology is the rapid rise connected cars (e.g., BMW, Toyota,..etc), smart utility meters (e.g., smart meters for smart meters for electricity, water,..etc), and consumer electronics (wearable gadgets like smartwatches and fitness tracker) with cellular connectivity. Source: Beecham Research Ltd. esim offers several advantages: Smallness: Sizes of wearable gadgets are reduced for comfort and style Ruggedness: Stand up shock, humidity, sweat and so on Integrity: No crack open of device to replace SIM card Independent Connectivity: provision and change service providers OTA
Who is Behind esim World s largest GSMA mobile operators Major SIM and chipset vendors GSMA Specification Specification focuses on: esim Architecture, Remote SIM Provisioning (RSP) architecture, and security functions within the RSP architecture

Key Benefits Consumers More choice of devices Multiple devices connected MNOs Maintain customer freedom of choice Any subscription from any Operator for any device User controlled Consumers are in charge, remote management of subscriptions Overall cost reduction Less paper. Less stock. Less complexity leads to more productivity and profitability New revenue streams More connected devices, more touchpoints with consumers. Long term flexibility MNOs are more agile and future proof when a change of subscription is needed in the field

High-Level Architecture for M2M Devices Source: Gemalto
High-Level Architecture for Consumer Devices LPA (Local Profile Assistant) is located on the device and takes end user s orders (e.g., profile download and execution of next profile management actions on the euicc) Data Preparation+ packages, encrypts, and binds profiles to the respective EID and securely downloads these profiles onto the euicc using the ES8+ interface. The end user is the one who triggers the RSP procedure. Source: COMPRION

Deployment Scenarios MNO SM-DP MNO Subscriptions SM-DP SM-SR SM-DP+ SM-DP+ SM-SR Gemalto, G&D, Oberthur, etc Consumers M2M Non-MNO Data Center Consumers M2M MNO Data Center Other MNO or OEM Non-MNO Data Center Option I: Non-MNO Data Center Pros: Time to market because only simple integration is required The non-mno data center has already GSMA Certification, which can take long time (almost a year) to obtain Easily orchestrate software updates Cons: Regulatory issue (e.g., China said SM- DP must be hosted in china) Option II: Hybrid Approach Pros: Full control over SM-DP/+ Can host a third party profiles Cons: The fees associated with the use of SM- SR owned by other MNO or OEM can be costly if the number of requested SM-SR transactions is high
Deployment Scenarios (continued) MNO SM-DP+ Consumers SM-DP SM-SR M2M MNO Data Center Other MNO or OEM SM-SR Non-MNO Data Center Option III: MNO Data center Pros: Full control of the provisioning system, thereby avoid any potential security issue Cons: For security purpose, Data Center needs to be certified by GSMA. This costs money, requires proper training for staff from security point of view, and also requires time (about a year) In case SM-SR must be hosted by OEM (e.g., BMW has its own SM-SR) In case of SM-SR Change (e.g., transferring the ISD-R keys after end of contract)
