I’m experiencing the ‘Cellular Plans From This Carrier Cannot be Added’ error message
This error
may show if you are trying to install an eSIM on a network-locked device.
You can check
if your device is locked by following the steps below:
Go to
Settings > General, and tap About.
Under Carrier
Lock, you should see a message that says No SIM restrictions. If you don’t see
that message, please contact your carrier to have your device unlocked.
If you have
confirmed with your current provider that your device is unlocked, please
contact us again.
