An eSIM, short for "embedded Subscriber Identity Module," is a digital SIM card that's built directly into a smartphone, tablet, smartwatch, or other connected device. Unlike traditional physical SIM cards, an eSIM is programmed into the device's hardware. It does exactly the same job as a traditional SIM, but without any of the hassle, inconvenience or fiddly bits of plastic.
eSIM technology provides several benefits
Users can switch between mobile carriers and plans without needing to physically swap out SIM cards. This can be especially useful for travellers who want to use local carriers while abroad.
eSIM technology offers convenience to users because they no longer need to physically insert or replace SIM cards when changing mobile carriers or plans. It also simplifies the process of activating new devices or switching between devices, as it can be done remotely.
Many devices equipped with eSIMs also have physical SIM card slots, allowing users to have two active phone numbers on the same device.
Users can activate or change their mobile plan remotely by downloading the necessary information from a carrier's app or website. This eliminates the need for a physical SIM card to be mailed or picked up from a carrier's store.
eSIMs eliminate the need for a physical SIM card slot, freeing up space within the device for other components or design improvements.
