Evolution of SIM cards. An eSIM is not removable.

An eSIM (embedded SIM) is a form of SIM card that is embedded directly into a device as software installed onto a eUICC chip. First released in March 2016, eSIM is a global specification by the GSMA that enables remote SIM provisioning; end-users can change mobile network operators without the need to physically swap a SIM from the device. [1] eSIM technology has been referred to as a disruptive innovation for the mobile telephony industry. [2] [3] Most flagship devices manufactured since 2018 that are not SIM locked support eSIM technology; [4] as of October 2023, there were 134 models of mobile phones that supported eSIMs. In addition to mobile phones, tablet computers, and smartwatches, eSIM technology is used for Internet of things applications such as connected cars (smart rearview mirrors, on-board diagnostics, vehicle Wi-Fi hotspots), artificial intelligence translators, MiFi devices, smart earphones, smart metering, GPS tracking units, database transaction units, bicycle-sharing systems, advertising players, and closed-circuit television cameras. A report stated that by 2025, 98% of mobile network operators were expected to offer eSIMs; [5] they can also be purchased from fintech firms such as Revolut and Wealthfront or via online marketplaces such as Airalo.

The eUICC chip used to host the eSIM is installed via surface-mount technology at the factory and uses the same electrical interface as a physical SIM as defined in ISO/IEC 7816 but with a small format of 6 mm × 5 mm. Once an eSIM carrier profile has been installed on an eUICC, it operates in the same way as a physical SIM, complete with a unique ICCID and network authentication key generated by the carrier. [6] If the eSIM is eUICC-compatible, it can be re-programmed with new SIM information. Otherwise, the eSIM is programmed with its ICCID/IMSI and other information at the time it is manufactured, and cannot be changed. One common physical form factor of an eUICC chip is commonly designated MFF2. [7] All eSIMs are programmed with a permanent eSIM ID (EID) at the factory, which is used by the provisioning service to associate the device with an existing carrier subscription as well as to negotiate a secure channel for programming. [8]

The GSMA maintains two different versions of the eSIM standard: one for consumer and Internet of things devices [9] and another for machine to machine (M2M) devices. [10]

History

In November 2010, the GSMA began discussing the possibility of a software-based SIM. [11]

In March 2012, at the meeting of the European Telecommunications Standards Institute, Motorola noted that eUICC is geared at industrial devices, while Apple foresaw eSIMs in consumer products. [12]

A first version of the standard was published in March 2016, followed by a second version in November 2016. [13]

In February 2016, Samsung released the Samsung Gear S2 Classic 3G smartwatch, the first device to implement an eSIM. [14]

In March 2017, during Mobile World Congress, Qualcomm introduced a technical solution, with a live demonstration, within its Snapdragon hardware chip associated with related software (secured Java applications). [15]

In September 2017, Apple first introduced eSIM support with the Apple Watch Series 3. [16] In 2018, it introduced it to iPhone, with the iPhone XS [17] and iPhone XR, [18] and iPad, with the iPad Pro (3rd generation). [19] The first iPhone models to not have a SIM card tray and work exclusively with eSIM were the iPhone 14 and iPhone 14 Pro, announced in 2022. [20] Outside the United States, all iPhone models continue to be sold with support for physical SIM cards, but the iPad Air (6th generation) and iPad Pro (7th generation), announced in 2024, work exclusively with eSIM. [21]

In October 2017, Google unveiled the Pixel 2, the first mobile phone to use an eSIM, available via its Google Fi Wireless service. [22] In 2018, Google released the Pixel 3 and Pixel 3 XL and in May 2019, the Pixel 3a and Pixel 3a XL, with eSIM support for carriers other than Google Fi. [23] [24] [25] In October 2019, Google released the Pixel 4 and Pixel 4 XL with eSIM support. [26]

Motorola released the 2020 version of the Motorola Razr, a foldable smartphone that has no physical SIM slot since it only supports eSIM. [27]

In July 2018, Plintron implemented the eSIM4Things Internet of things product. [28]

In December 2017, Microsoft launched its first eSIM-enabled device, the Microsoft Surface Pro LTE. [29] In 2018, it introduced eSIM to the Windows 10 operating system. [30] and

Samsung shipped Samsung Galaxy S21 and S20 series smartphones in North America with eSIM hardware onboard but no software support out of the box. The feature was enabled with the One UI version 4 update in November 2021. [31]

In June 2018, Singapore sought public consultation on introducing eSIM as a new standard. [32]

In 2023, there were 650 million installed devices with eSIM capability. [33]

A smartphone, often simply called a phone, is a mobile device that combines the functionality of a traditional mobile phone with advanced computing capabilities. It typically has a touchscreen interface, allowing users to access a wide range of applications and services, such as web browsing, email, and social media, as well as multimedia playback and streaming. Smartphones have built-in cameras, GPS navigation, and support for various communication methods, including voice calls, text messaging, and internet-based messaging apps.

A SIMcard is an integrated circuit (IC) intended to securely store an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephone devices. SIMs are also able to store address book contacts information, and may be protected using a PIN code to prevent unauthorized use.

As for MMS, mobile service must be activated. Development of RCS began in 2007 but early versions lacked features and interoperability; a new specification named Universal Profile was developed and has been continually rolled out since 2017.

Remote SIM provisioning is a specification realized by GSMA that allows consumers to remotely activate the subscriber identity module (SIM) embedded in a portable device such as a smart phone, smart watch, fitness band or tablet computer. The specification was originally part of the GSMA's work on eSIM and it is important to note that remote SIM provisioning is just one of the aspects that this eSIM specification includes. The other aspects being that the SIM is now structured into "domains" that separate the operator profile from the security and application "domains". In practise "eSIM upgrade" in the form of a normal SIM card is possible or eSIM can be included into an SOC. The requirement of GSMA certification is that personalisation packet is decoded inside the chip and so there is no way to dump Ki, OPc and 5G keys. Another important aspect is that the eSIM is owned by the enterprise, and this means that the enterprise now has full control of the security and applications in the eSIM, and which operators profiles are to be used.
