Difference between M2M and ConsumerIn 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)

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

Wearables

Tablets and smartphones

Laptops

Cars

Smart Metering Devices

Others (PoS and Medical Devices)

What is an Embedded SIM (eSIM)

eSIM or eUICC is a programmableSIM that can be seamlessly and securely provisioned over the air.

Facilitates easy switch between MNOs, allowing consumers to select the MNO that offers best deal

Enabler for faster deployment and adoption of Internet of Thing (IoT)

(*)

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.

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.

Why Introducing eSIMThe 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.

eSIM offers several advantages: Smallness: Sizes of wearable gadgets are reduced for comfort and style Ruggedness: Stand up shock, humidity, sweat and so onIntegrity: No crack open of device to replace SIM cardIndependent Connectivity: provision and change service providers OTA

Who is Behind eSIMGSMA

World’s largestmobile 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

More choice of devices

Maintain customer freedom of choice

User controlled

Consumers are in charge, remote management of

subscriptions

Any subscription from any Operator for any device

Multiple devices connected

Consumers

MNOs

Overall cost reduction

Less paper. Less stock. Less complexity leads to more productivity and profitability

More connected devices, more touchpoints with consumers.

New revenue streams

MNOs are more agile and future proof when a change of subscription is needed in the field

Long term flexibility

Example of revenue stream – A US MNO

High-Level Architecture for M2M Devices

High-Level Architecture for Consumer Devices

The end user is the one who triggers the RSP procedure.

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)

Source: COMPRION

Data Preparation+ packages, encrypts, and binds profiles to the respective EID and securely downloads these profiles onto the eUICC using the ES8+ interface.

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)

Non-MNO Data Center

Non-MNO Data Center

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

Other MNO or OEMSM-SR

MNO Data Center

Non-MNO Data Center

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)

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)
