If you wanted to provide cellular connectivity, you’d need a SIM card. But in a world where people can get anything they want delivered to their door at within the hour, at the touch of a button—was it ever going be enough for the customer of the 2020s? The eSIM is the next big thing in our connected world. Networks are provisioned to devices over the air. No plastic. No lag. No paperclips. No brainer. Apple has fired the starting pistol. Its introduction of the eSIM into the iPhone is the catalyst for mass and swift adoption. The nature of mobile connectivity has changed, and the physical SIM card has become outdated. It is no longer viable to expect device manufacturers and distributors – not to mention customers – to stay wedded to the hassle and cost of removable SIM cards, just to get their device online. Network operators and device makers must embrace the recent standardisation of eSIM and evolve the systems and processes across the supply chain to support widespread deployment and use of eSIM- enabled devices. At Truphone, we’re at the forefront of the eSIM revolution. We’re publishing this cookbook to share some simple recipes on how to create new customer experiences and smooth the journey for the next generation of devices to get connected. WHAT IS AN eSIM? Let’s start at the beginning. The eSIM is the new standard in SIM technology. It was developed by the GSMA and has already become widely accepted by the telecoms market. Sometimes it’s called the embedded SIM, and occasionally you’ll see the initials eUICC (Embedded Universal Integrated Circuit Card). It differs from traditional SIM cards in several essential ways. For one thing, the eSIM is activated using remote SIM provisioning—the capability to configure the SIM for any mobile operator remotely or through the use of an application on the device. This means the SIM ‘card’ can be embedded inside a connected device, for the lifespan of the hardware. How does an eSIM get set up? Simply put – with a remote SIM provisioning (RSP) platform – the process of installing an operator’s connectivity credentials, known as an eSIM profile, is simplified by using a standardised, secure and remote ‘over the air’ process. Crucially, it’s widely considered to be as secure as existing traditional SIM technology. Secure data centres are used to host the connectivity profiles from the mobile network operator, ready to be installed into the eSIM. And, the GSMA has established a certification for companies which provide remote SIM provisioning platform services according to the same security requirements that exist for the production of physical SIM cards. HOW DOES REMOTE SIM PROVISIONING WORK? Two standards for remote SIM provisioning currently exist to support machine to machine (M2M) and consumer use cases. Both standards share similar infrastructure components and are often supported by the same platform. Remote SIM provisioning unlocks the flexibility of an eSIM to allow mobile connectivity, so that a device can be configured once it has been manufactured and deployed. This is particularly beneficial for M2M and Internet of Things (IoT) devices, where the configuration process is performed remotely from the device itself. For consumer devices, mobile connectivity can be enabled by simply scanning a QR code, or through an application installed on the device.

Various other configuration data are needed, such as APNs, network access rules, data usage policies around roaming, tethering, and support for services such as voice over Wi-Fi (VoWifi), voice over LTE (VoLTE) and mobile switching service (MSS). Right now, many devices are produced without the manufacturer knowing which mobile operator will be used to get the hardware online. This makes it hard to manage the configuration data and policies needed for that device to successfully connect to a network the first time. The integration of an entitlements server with a mobile network simplifies this process dramatically. Device configuration can be set up remotely and managed over a secure channel. Anything else? In eSIM-enabled consumer devices, mobile subscriptions are activated differently. While it’s possible to allow some devices to scan a QR code corresponding to a specific eSIM operator profile, other activation procedures may be more desirable for customers using devices such as tablets, laptops and wearables. Therefore, many manufactuers allow operators to embed specially-designed websheets (simplified access to a mobile operator website) onto the device. These allow for plans to be displayed, purchased, and activated while appearing native to the device operating system. Support for this integration often requires the operator to repurpose their existing e-commerce platforms to support the APIs and display requirements of different devices. Support for this websheets integration requires some changes by the mobile network operator to support the APIs and display requirements of certain devices whilst re-using existing e-commerce platforms. For the new eSIM-enabled iPhone and Android phones, it is also possible for mobile operators to include eSIM activation support in their existing mobile applications. This is achieved through specific eSIM APIs built into the operating system and in coordination with the remote SIM provisioning platform. THE CONNECTED Companion devices: COMPANION Wearables, partnered devices, smart watches. New devices such as the Apple Watch 4, Samsung Gear S3, Huawei Watch 2 are being designed and released with cellular connectivity support. The engineering effort to support high speed LTE and excellent battery life is to be applauded. For mobile operators, this offers a great new opportunity.
