How to Fix eSIM QR Code Activation Errors on iPhone [Full Guide]

  • by MicroEsim

Summer is here, and vacation begins. People are preparing everything needed for their international trips, like purchasing eSIMs. They activate a cellular plan from the carrier with no need for a physical SIM, which helps people avoid the hassle of switching to a physical SIM card after a long-awaited delivery.

However, when people try activating the newly bought eSIM for international travel, they face issues. They cannot activate the eSIM QR code on iPhone, encounter a failure activation message, or face other eSIM activation errors. It's incredibly frustrating. Are you one of them facing the same problems? Don't worry! This article will explore the reasons and solutions and recommend a more stable and easier-to-use eSIM card to help you avoid similar problems.

Common Issues with eSIM QR Code Activation on iPhone

Before heading to the solutions, it is essential to understand what causes problems, like eSIM not working issues on iPhone, eSIM stuck on activating on iPhone 15/14/13, etc. There are 3 main causes.

  • Network Issues: Any poor internet connections will greatly hinder eSIM activation, no matter if you are using a WIFI or cellular network. So, before activation, make sure you have a strong and stable network connection without issues.
  • Compatibility Issues: Not all iPhone models are compatible with eSIMs. Starting with the iPhone XS, iPhone XS Max, and iPhone XR, Apple introduced the eSIM feature. Since then, all iPhone models released, including the iPhone 11, iPhone 12, iPhone 13, iPhone 14, and iPhone 15 series, support eSIMs. But, even so, compatibility still depends on your location and carrier.
  • Carrier Issues: There are restrictions from carriers that may prevent you from activating eSIM. These include limitations to the number of eSIMs you can activate, restrictions to the country and region, using a carrier-locked phone, or account-specific issues such as unpaid bills or account suspensions.

Knowing these common reasons can better solve your problems. Now, let's have a look at fixes on how to address these problems. You can take action according to the specific reasons. But before proceeding, make sure you have a good network and strong signal in your area.

Fix 1. Check QR Code Availability

The first thing to do is to ensure that the QR code is valid. If you encounter error messages like "eSIM Cannot Be Added - This code is no longer valid", it indicates the eSIM QR code is scanned (by you or anyone else). For eSIM card on iPhone, the QR code error message from version 15 or below may also display like "Cellular Plan Cannot Be Added". Every eSIM QR code is only for one-time use. If it has been used, it will not work again. So, if you face the eSIM card no longer valid error, contact your eSIM provider to ask for a new QR code.

Fix 2. Check Carrier Compatibility

Ensure that both your iPhone and carrier support eSIM. Carriers worldwide support eSIM plans in over 190 counties and regions. However, some places are not available. eSIM on iPhone is not offered in mainland China, Hong Kong, and Macao. Now, learn how to check compatibility by following these steps.

Tip:

If you are using a MicroEsim, you can easily check device compatibility from the official eSIM Compatible Devices page.

To check if your iPhone is compatible with eSIM:

1. Go to Settings on your iPhone.

2. Enter the Cellular page.

3. If you see the option "Add Cellular Plan", your device supports eSIM. If you see none, consider using a compatible iPhone.

Then, to check if your carrier is compatible with eSIM in your country or region:

1. Go to Apple Support to check the "wireless carriers and worldwide service providers that offer eSIM service" list, which demonstrates different carriers that support eSIM in different regions with different eSIM activation methods.

2, If your carrier does not support eSIM in the country or region you want to visit, you may need to change to another one.

Fix 3. Check Carrier SIM Limitation

Another important thing to note is that you may use a carrier-locked iPhone, which requires you to use eSIM from a specific carrier. If you do, you may encounter an error message like "Your device can only use cell plans from a different carrier". Only an unlocked iPhone allows you to use eSIMs from any carrier. Here is how to check if your iPhone is carrier-locked.

1. Go to the Settings app.

2. Tap on General.

3. Scroll down and tap About.

4. If it says No SIM restrictions, your iPhone is unlocked and can use eSIM from any carrier. If it shows a carrier name, your iPhone is locked to that carrier. In this case, you will need to contact that carrier to unlock your phone. This process can vary by carrier and may involve certain requirements or fees.

3. Select Software Update to check for available updates.

Here's how to update your carrier settings.

1. Open Settings.

2. Go to General.

If the above methods are not helpful, try to restart your iPhone because it works to reset network settings and clear any temporary glitches that may be the potential cause.
