With eSIM, switching carriers and plans across borders is as easy as a few taps on your device. If you want to know what is an eSIM card, you are at the right place! In this comprehensive guide, we'll show you what eSIM is, everything you want to know about eSIM, and how to get and activate eSIM. Keep reading!

What is an eSIM Card? How Does an eSIM Card Work?

The eSIM card is a type of SIM card that is installed in a device in a physical manner as opposed to the normal SIM card that can be slid into a plastic tray. This makes it possible for users to have access to any operator that is in the provision of eSIM services without the use of physical SIM cards. In the case of an eSIM, it is built into the device and only requires the installation of a carrier "eSIM profile", and then connects a cell phone to a cellular network.

An eSIM card has the same features as a physical SIM card. Here is how an eSIM card works:

  • The eSIM is physically mounted into the PCBA (Printed Circuit Board Assembly) of the device and is therefore part of the hardware permanently.
  • You can load eSIM profiles from the carriers over the air by using software, where they often need to scan a special QR code or use an App of their carrier. This eradicates the nuisance of "physically" transferring SIM cards from one device to another.
  • Some of the eSIM-supported devices help a user to have more than one profile of the eSIM for one device and can interchange them. For instance, iPhones have the option to keep to eight eSIM profiles but at a time, only two are in use.
  • The eSIM will allow those who own the eSIMs to change from one carrier or plan to another without having to go back to a store or wait for the new SIM card to be delivered. This is particularly useful because locals can easily add international plans to reduce roaming charges.

What is the Advantage of eSIM?

The primary advantages of eSIM technology are its convenience, flexibility, and efficiency in managing cellular connectivity. The eSIM cards also do not require any swapping or shifting of SIM cards whenever a consumer switches from one carrier to another or changes their plan. This makes it easier for you to activate a new device or switch to a new carrier without having to run to the store or wait for a SIM card to be delivered to the mailbox.

As it is widely understood, a variety of electronic devices that incorporate built-in eSIM have the option to store multiple profiles (up to 20, with 2 activated at once). Moreover, eSIM technology encompasses various security enhancements such as remote SIM locking and encryption of the data for users. In addition to offering a hassle-free experience to consumers, eSIMs help in the cause of environmental conservation by cutting down on the amount of plastics used in the making and disposal of SIM cards. Next, we will show you the differences between eSIM and SIM card.
