Everything you need to know about eSIM

This guide explores everything you need to know about eSIMs, including their benefits, differences from physical SIMs, device compatibility, and a detailed look at Exetel's eSIM plans.

What is an eSIM? 

An eSIM (embedded SIM) is a small chip that is embedded in selected devices, eliminating the need for a physical SIM card. It functions like a traditional SIM card, enabling you to connect to your mobile network. However, instead of swapping SIM cards to change carriers or plans, you can download a digital profile from your carrier. 

This technology has been adopted widely due to its ability to streamline mobile connectivity. eSIMs enable over-the-air activation, removing the need to visit a store or wait for a SIM card to arrive in the mail. Additionally, eSIMs are crucial in the growing ecosystem of IoT (Internet of Things) devices, such as smartwatches, tablets, and even vehicles, where physical SIM slots are impractical.

The eSIM's integration into these devices underscores its role as a future-proof solution for modern connectivity needs. 

Difference between eSIM and physical SIM 

The physical SIM card has been a staple of mobile technology for decades, but its limitations are evident in today’s fast-paced digital landscape. For example, travellers often face the inconvenience of purchasing and swapping local SIM cards when abroad. eSIM technology eliminates this hassle, enabling users to add and switch profiles directly on their devices. Businesses, too, benefit from the streamlined management of multiple devices without dealing with physical SIM cards, saving time and resources.
