Let's see the 4 different ways to activate an eSIM-enabled consumer device, i.e., the various methods to link an eSIM-based mobile subscription and an eUICC-equipped consumer device:
1. QR code-based eSIM voucher activation
2. By-default SM-DP+ address-based activation
3. GSMA's Root Discovery Service-based eSIM activation
4. Initial connectivity
1. QR code-based voucher activation.
Let's assume a user wants to buy an eSIM-based mobile subscription – at an operator's point of sales or online – for her/his eSIM-capable device s/he already owns or that s/he'll buy later.
The first option for mobile operators consists of providing customers with a QR code eSIM voucher to be scanned with the smartphone to download the eSIM profile (corresponding to the subscription just bought) to her/his device.
Said differently, this QR code contains a set of information (e.g., SM-DP+ address…) that tells the device where to get its final eSIM profile from.
Then there are 3 pre-requisites:
- A primary connection must be available for attaching the smartphone and the SM-DP+. Basically, SM-DP+ is a platform that stores digital eSIM profiles. The primary connection can be based on Wi-Fi or an eSIM bootstrap profile provided by the OEM.
- The OEM vendor must embed the LPA (Local Profile Assistant) in the device OS: it is an application that allows the eSIM profile download to the eUICC and local profile management on the device by the end-user (i.e., QR code scanning).
- The mobile operator must equip its points of sale with printers to stamp the QR code or provide physical paper activation vouchers to its users (see below the example of StarHub in Singapore). In both cases, there is a risk of loss or theft of the QR code.

There are three more things to remember:
- This voucher activation method is widely used for most launches of eSIM-enabled consumer devices, such as Samsung's Gear S2 3G smartwatch, e.g., TIM Italy, Orange France. Interestingly Apple's latest 2018 generation eSIM-compliant iPhones also rely on QR code.

- This option is suitable for open market devices only, i.e., devices sold independently from a mobile subscription.
- Recently, a new generation of QR codes makes its appearance: the generic eSIM voucher allows us to allocate and activate numerous new subscriptions via a single QR code.
2. The SM-DP+ address is set by default in the eUICC.
Operators can alternatively sell a mobile subscription with an operator-branded handset.
In this context, the second option to activate the eSIM subscription consists of pre-provisioning the device's eUICC with the operator's remote SIM provisioning platform (SM-DP+) address during the device manufacturing stage. Consequently, once switched on for the first time, the device directly connects to the SMDP+ server to retrieve its full eSIM profile.
This makes adoption and activation of eSIM technology simpler thanks to excellent customer experience.
However, mobile operators need to work closely with OEMs to customize the devices to their network. This may generate non-negligible inventory and supply chain costs compared to vanilla open market devices.
A primary connection is still required for attaching the device the first time to the network's SM-DP+ server.
Finally, this mechanism only works for operator-subsidized eSIM-enabled handsets; the user has to buy the operator's subsidized handset together with the mobile operator's subscription.
Thus it is a perfect fit for markets with high post-paid penetration, such as the US.
3. GSMA's Root Discovery service-based eSIM activation.
Since the second semester of 2017, a third option exists to activate a consumer eSIM-capable device remotely. Indeed, Thales deployed the first solution of this kind.
It is called Subscription Management Root-Discovery Service (i.e., SM-DS); indeed, it intends to enhance further the customer experience of connecting an open market consumer eSIM device to the mobile network offer of the user's choice.
In this case, the user purchases separately her/his eSIM-based mobile subscription and smartphone. Once switched on for the first time, the device will automatically and instantly retrieve over-the-air the eSIM profile (corresponding to the mobile subscription just bought by the user) destined for the device.
It provides a true out-of-the-box mobile subscription activation and makes the adoption of eSIM technology a lot simpler for end-users.
How is this magic made possible?
As for the QR code activation process, it requires:
- A minimum first level of native connectivity for the devices for attaching the smartphone with the SM-DS platform.
- LPA to be supported by the device.
Besides, mobile operators and other mobile connectivity providers must also connect their SM-DP+ platform to the SM-DS platform (what they are increasingly doing).
So far, the GSMA Root Discovery Service is provided by the GSMA and is now used by an increasing number of mobile operators and device makers.
4. Initial connectivity via Thales Instant Connect.
Today, the eSIM profile download requires the eSIM-ready device to be connected to the mobile network through a first sort of Internet connectivity (e.g., Wi-Fi, smartphone tethering, bootstrap connectivity).
In an approach to always simplify the customer journey as well as possible and to support its digitalization, Thales works on solutions allowing an out-of-the-box initial connectivity channel for the download of eSIM profiles.
This is in addition to Wi-Fi, smartphone tethering, and bootstrap channels, as explained above.
This multi-channel approach will maximize the activation of eSIM capable devices while providing a seamless customer experience. As a result, this delivers value for all the ecosystem's key stakeholders: Mobile Network Operators, Device Makers, eSIM makers, end-users.
In June 2019, Thales announced a revolutionary solution for providing initial mobile connectivity: Thales Instant Connect.
It allows OEMs and mobile operators to remotely and automatically provide initial mobile connectivity to eSIM-ready devices at power-on (as they come unconnected), wherever they are, while drastically simplifying OEMs' supply chain and enhancing the user experience.
This solution won two awards in 2019: Future Digital Award for Technology and Innovation (from hi-tech analyst firm Juniper Research) and IoT Global Award.
Thales has been shortlisted with this solution at the 2020 Global Mobile Awards for the Best Mobile Technology Breakthrough award.
CONCLUSION: USER EXPERIENCE AT THE VERY CENTER OF eSIM ACTIVATION MODE EVOLUTION
At the end of 2018, more than 230 mobile operators, OEM, and automotive makers have deployed eSIM remote subscription platforms globally. It evidences the willingness of stakeholders to address the eSIM opportunity adequately.
But the optimization of the user experience is at the center of everyone's concerns; it requires continuous work together to deploy globally an interoperable & seamless eSIM scheme able to address the tremendous need for mobile connectivity of billions of IoT devices.
In December 2020, independent global industry analysis firm Counterpoint has ranked Thales number 1 provider for eSIM solutions for the second year in a raw.
