How to fix the “Unsupported eSIM” error message on your iPhone

Imagine this: You've just installed an eSIM, ready to get started right away, but suddenly you get an error message: "This eSIM is from a carrier not currently supported on this iPhone." Annoying, right? This issue often occurs if your iPhone is locked to a specific carrier and therefore doesn't accept plans from other providers. Don't worry—in this article, we'll explain how to find out if your iPhone is locked and what you can do to fix the problem.


Why does the error message “Unsupported eSIM” appear?

The most common reason for this message is a network lock. This means that your iPhone is restricted to a specific carrier—for example, the one from which you purchased the device. iPhones sold directly by Apple are usually unlocked and can be used with any eSIM or SIM card.


How to check if your iPhone is unlocked

Before you tackle the problem, you should first determine whether your iPhone is locked to a carrier. It's easy:

  1. Open Settings on your iPhone.
  2. Go to General and then About .
  3. Scroll down to the Carrier Lock line.
    • No SIM restrictions : Your iPhone is unlocked and can be used with any eSIM.
    • Any other message means that your device is tied to a provider.

What to do if your iPhone is locked?

If your iPhone is actually locked, only the carrier from whom you purchased the device can unlock it. Here's how to do it:

  1. Contact your provider's customer service
    Call support or use live chat. Explain your issue and request to unlock your device.

  2. Request unlocking
    Many providers can unlock the phone wirelessly. However, the process can take several days, so please allow some time.

  3. Patience pays off
    Some providers have a minimum waiting period after purchase before they allow unlocking.

💡 Tip : Third-party providers offer unlocking services for a fee. However, these often come with risks and could void your iPhone's warranty. Only use such services if you're sure they're trustworthy.

What should I do if the eSIM still doesn't work?

If your iPhone is unlocked but the eSIM is still not recognized, it could be related to activation. Here are a few things you can try:

  • Check the installation instructions you received from your eSIM provider.
  • Make sure your iPhone model is eSIM compatible.
  • Restart your iPhone and try installing the eSIM again.

If nothing helps, you can always contact your eSIM provider. At VoiSim , our 24/7 customer support is available to ensure your eSIM works smoothly.
