If you're trying to install an eSIM on your iPhone and you see a message that says "Cellular Plans From This Carrier Cannot Be Added," that may mean your iPhone is network-locked.
Here's how you can verify if your phone is locked to one particular network:
- Go to "Settings"
- Select "General"
- Select "About"
- Scroll down to look at "Carrier Lock"
- If next to "Carrier Lock," it says the name of a carrier, that means your phone is locked to carrier and it won't be able to accept a new carrier until this is changed. Contact your carrier to have the phone unlocked.
- If next to "Carrier Lock," it says "No SIM restrictions," that's good news! It means your phone will be able to connect to another network.
