Determining whether your mobile device supports eSIM technology is crucial before purchasing an eSIM plan. Fortunately, there is a quick and straightforward way to check your phone's compatibility using a USSD code. This guide will walk you through the steps to verify if your device is equipped with eSIM capabilities, ensuring a seamless experience when switching to eSIM technology.

What is eSIM, and why check compatibility?

An eSIM, or embedded SIM, is a digital SIM embedded directly into your device. This allows you to activate a mobile network plan without a physical SIM card. To use an eSIM, your device must have a built-in eSIM chip, and knowing if your device supports this technology can save you time and hassle.

How to check eSIM compatibility using USSD

USSD (Unstructured Supplementary Service Data) codes provide a quick method to access information about your phone’s capabilities directly from the device’s dial pad. Here’s how to use a USSD code to check if your phone supports eSIM:

Step-by-step guide:

  1. Open the phone app:
    • On your smartphone, open the Phone app as if you are going to make a call.
  2. Enter the USSD code:
    • On the dial pad, enter *#06#. This is the standard USSD code used to display device information.
  3. View device information:
    • After entering the code, a screen will automatically pop up displaying various identifiers associated with your device.
    • Look for an identifier labelled EID (Embedded Identity Document). The presence of an EID number confirms that your phone supports eSIM. The EID is usually a 32-digit number that uniquely identifies the eSIM embedded in your device.

Note: This method is widely used for iPhones and some Android devices. The actual display may vary slightly depending on your device model and operating system version.

Alternative method: checking through device settings

If the USSD code method does not display the information or you want to double-check:

  • For iPhones:

    1. Navigate to Settings > General > About.
    2. Scroll down to find the EID. If it is listed, your iPhone is eSIM compatible.
    3. Additionally, check the "Carrier Lock" status. If it says "No SIM restrictions," your device is not carrier-locked, allowing you to use any eSIM.

  • For Android devices:

    1. Go to Settings > About phone.
    2. Look for the EID under the "Device details" section. You might need to tap a prompt such as "Tap to show info" to display the EID number.
    3. If the EID is listed, your Android phone supports eSIM.

Understanding the results

  • If EID is present: Your device supports eSIM, and you can enjoy the flexibility and benefits of digital SIM technology.
  • If EID is not present: Your device likely does not support eSIM. You may need to use a physical SIM card or upgrade to a newer model that includes eSIM technology.

Why use USSD to check compatibility?

Using a USSD code is one of the fastest and most convenient methods to check your phone's eSIM compatibility. This method does not require internet access and provides immediate results, making it ideal for users who want a quick check.

Conclusion

Ensuring that your phone supports eSIM before purchasing a data plan is crucial for a hassle-free experience. With this guide, you can easily verify your device’s compatibility using a USSD code or navigating through your device settings.
