How to fix Error: “Cellular Plans From This Carrier Cannot Be Added”
After activating your eSIM using a QR code or manual activation code, you may encounter the following error message:
Cellular Plans From This Carrier Cannot Be Added
This message typically indicates that your device is carrier-locked, meaning it cannot install eSIM plans from carriers other than the one that originally sold the device.
How to Check if Your Device Is Carrier-Locked
You can verify your device lock status by following these steps:
- Open Settings
- Tap General
- Tap About
- Look for the field Carrier Lock
You should see:
- No SIM restrictions → Your device is unlocked
- Any other message → Your device is locked
If the device is locked, it will block eSIM activation from third-party carriers.
Solutions
To resolve this issue, please contact your mobile carrier and request that they unlock the device. In most cases, the unlock can be completed remotely (over-the-air) through the carrier’s Customer Service hotline or live chat.
Once the device is successfully unlocked, you can return to your eSIM activation process and install the plan without issues.
