An embedded sim (eSIM) based on the eUICC standards is a hardware-based sim card that acts like a regular sim card and is universally compatible with any mobile carrier or technology (2G, 3G, 4G, 5G, LTE, NB-IoT, etc.). Also, the eSIM can support multiple carrier profiles simultaneously.
The eSIM is available in several formats. First, as an embedded version: a programmable SIM card physically connected (soldered) to the motherboard, but also as a 3-in-1 plastic form factor. The embedded version does everything an external SIM card does, only you can’t physically remove it without breaking open the device and unsoldering the chip. At first, this may seem problematic. But eSIM technology makes it easier to switch providers. Switching profiles is accomplished via Over-the-Air (OTA) commands sent to the device versus physically changing the SIM card. Benefits include preventing Customer lock-in and streamlining logistical efficiencies.

Many people know the consumer sim card from their cell phones. Again, a movement from regular sim to eSIM is underway. However, consumer eSIMs and IoT eSIMs are quite different. In the consumer model, the end user chooses and initiates a request for the desired carrier profile, which ensures that the carrier profile is placed on the device. IoT devices are managed differently. It is essential that enterprises have a way to remotely manage and assign the desired carrier profile.
eSIM also opens new avenues for different applications of mobile technology. Take the car as an example. It may sound futuristic, but currently there are already millions of connected cars through eSIM. The connected cars rely on networks to provide a variety of services to the driver, including navigation, entertainment and roadside assistance. With critical real-time services such as navigation and roadside assistance, there is great value in automatically choosing the best available network connection.
