If you're interested in using eSIM but aren't sure if your smartphone or tablet (or a family member's) is compatible, this article is for you.
Simply put, the key is to check for something called an EID.
This article explains what EID is and how to check for it step-by-step for both iPhone and Android devices.
EID, or Embedded Identity Document, is a unique identifier associated with an eSIM chip (module) inside a connectivity device like smartphones.
Think of an eSIM chip as a container. When you install an eSIM profile into this chip, it enables it to function similarly to a traditional physical SIM card.
If your device has an EID number, it means it is equipped with an eSIM chip.
In other words, the presence of an EID is a straightforward and easy way to confirm that your phone is eSIM-compatible.
There are several ways to verify if a device has an EID, but the most common and effective methods are the following two:
Let's dive into each method with visual images.
Just like making a call, open the Phone app on your iPhone and dial:
*#06#
Remember to start with '*', then sandwich the '06' with the '#'.

Do not worry, this won't initiate an actual phone call.
As soon as you enter the final '#', a screen displaying several numbers and barcodes, like the one shown below, should appear.

If 'EID' is displayed among the information (typically on top), it means your iPhone supports eSIM. The EID is a 32-digit number.
FYI, entering specific numbers like this on the dial screen to execute certain actions is known as using a 'USSD code'. USSD stands for Unstructured Supplementary Service Data.
You can also check for EID from within the Settings app.
Again, if an EID is present, it means your device is eSIM compatible.
Navigate to Settings β General β About. You'll find the EID displayed around the middle of the screen, as shown below, if the iPhone supports eSIM.

On Android devices, go to Settings β About phone to find if EID exists. It's usually located around the middle of the screen, under the 'Device details' section.
Initially, you might see a prompt like 'Tap to show info' instead of the actual number. Once you tap, the EID number and EID QR code will be displayed in a modal.

Now you know how to check eSIM compatibility. If your device supports it, you're ready to enjoy the flexibility and seamless connectivity that eSIM technology offers!
