What is an eSIM?

An eSIM, or embedded SIM, is a type of SIM card that is embedded directly into a device, such as a smartphone, tablet, or smartwatch, eliminating the need for a physical, removable SIM card. The “e” in eSIM stands for “embedded” or “electronic.

What are the benefits of eSIM cards?

No need to setup

Unlike traditional SIM cards that are physical, removable chips, eSIMs are integrated into the device’s hardware during manufacturing. This means there’s no physical card for users to insert or replace.

Can be activated remotely

eSIMs can be remotely activated and configured by the mobile network operator or service provider. Users can download the necessary credentials and settings over-the-air, simplifying the activation process.

Switch between profiles

eSIMs support the storage of multiple SIM profiles on a single chip. This feature allows users to switch between different mobile carriers or plans without needing to physically swap out a SIM card.

IoT compatible

eSIM technology is particularly beneficial for smaller and more compact devices, such as smartwatches or Internet of Things (IoT) devices, where space is limited and a physical SIM card slot may be impractical.

Global Roaming options

Users can easily switch between mobile carriers or plans when traveling internationally by downloading the relevant eSIM profile. This flexibility makes global roaming more convenient and efficient.

Embedded Security

eSIMs incorporate security features to protect user information and authentication. The use of embedded security elements helps safeguard the digital identity of the device and user.

Future Proofed

eSIM technology is considered future-proof because it facilitates easier device management, software updates, and provisioning of new services without requiring a physical SIM card replacement.

It’s important to note that while eSIM technology is becoming more widespread, not all devices or mobile carriers support eSIMs.
