Why Does This Error Appear?

The most common causes are:

• the phone has a SIM lock (carrier lock),
• the device does not support eSIM,
• the eSIM has already been added before,
• the iOS system is outdated.

How to Fix It?

1. Check if the iPhone is carrier unlocked

Go to:
Settings → General → About → Carrier Lock

It should display:
No SIM Restrictions

2. Make sure the phone supports eSIM

Not all iPhone models support this feature (for example, models older than iPhone XS).

3. Update iOS

Go to:
Settings → General → Software Update

Install the latest available version of iOS.

4. Try adding the eSIM again

Make sure you have a stable Wi-Fi connection and scan the QR code again.

What Should You Do If the Problem Still Occurs?

If the error still appears, the issue may be related to the device or the carrier. In that case, it is best to contact support for individual assistance and further troubleshooting.
