ESIM

An eSIM (embedded SIM) is a form of SIM card that is embedded directly into a device as software installed onto an 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. eSIM technology has been referred to as a disruptive innovation for the mobile telephony industry. Most flagship devices manufactured since 2018 that are not SIM locked support eSIM technology; 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.

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. 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. All eUICCs are programmed with a permanent eUICC 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.

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

In November 2010, the GSMA began discussing the possibility of a software-based SIM. 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. 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). In June 2018, Singapore sought public consultation on introducing eSIM as a new standard. In 2023, there were 650 million installed devices with eSIM capability.

In February 2016, Samsung released the Samsung Gear S2 Classic 3G smartwatch, the first device to implement an eSIM. In September 2017, Apple first introduced eSIM support with the Apple Watch Series 3. In 2018, it introduced it to iPhone, with the iPhone XS and iPhone XR, and iPad, with the iPad Pro (3rd generation). 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. Outside the United States, all iPhone models continue to be sold with support for physical SIM cards, but the iPad Air (6th generation), iPad Pro (7th generation), and iPad Mini (7th generation), announced in 2024, work exclusively with eSIM.

In October 2017, Google unveiled the Pixel 2, the first mobile phone to use an eSIM, available via its Google Fi Wireless service. 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. In October 2019, Google released the Pixel 4 and Pixel 4 XL with eSIM support. In 2025, US-sold Pixel 10 series devices (except the Pixel 10 Pro Fold) lack physical SIM card slots, therefore requiring eSIM, when non-iPhone competitors such as Samsung and OnePlus include both physical SIM and eSIM support in the US.

In December 2017, Microsoft launched its first eSIM-enabled device, the Microsoft Surface Pro LTE. In 2018, Microsoft also introduced eSIM to the Windows 10 operating system. In July 2018, Plintron implemented the eSIM4Things Internet of things product. Motorola released the 2020 version of the Motorola Razr, a foldable smartphone that has no physical SIM slot since it only supports eSIM. Samsung shipped the Samsung Galaxy S21 and S20 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.

In 2023 the Israeli bombardment, electricity blockades and fuel shortages had caused the near-total collapse of Gaza’s largest cell network providers. eSIMs have been used to provide internet access to people living there by allowing them to connect to remote networks including Israeli networks. eSIMs have been donated through schemes like Connecting Humanity, run by Mirna El Helbawi who discovered that eSIMs could be used to reconnect people in Gaza. By December 2023, 200,000 people living in Gaza (around 10% of the population) had received internet access through an eSIM.

Why is eSIM Ideal for Frequent Business Travelers?

Frequent business travel comes with tight schedules, back-to-back meetings, and constant communication. Whether you are flying to another state or another continent, staying connected is not optional. You need reliable mobile data the moment you land. This is where eSIM technology makes a big difference. eSIM stands for “embedded SIM.” It is built directly into your phone or device, so you do not need a physical SIM card. For business travelers, this small change creates big advantages. Let’s explore why eSIM is the ideal solution for professionals who travel often. 1. INSTANT CONNECTIVITY AFTER LANDING Time is money for business travelers. Waiting in long airport lines to buy a local SIM card wastes both time and money. With an eSIM, you can: * Purchase a mobile plan online before your trip * Activate it instantly by scanning a QR code * Get connected to a local mobile network immediately after you arrive. There is no need to search for SIM vendors or deal with language barriers. You step off the plane, and your phone is ready to work. 2. NO MORE SIM CARD SWAPPING Traditional SIM cards can be inconvenient. You must remove your current SIM, store it safely, and insert a new one.
