If you try to add a new cellular plan to your device and your carrier network doesn’t support it, you’ll be given an error message. There are a few reasons why this is the case:
- Your device is not compatible with the new cellular plan - some can only support specific networks.
- Your device may be locked to your existing carrier as part of the contract you have, in which case you’d need to unlock it or get a new device.
- Some carriers have restrictions on eSIM devices and other types of software.
If you’re getting an error message like this one, it is worth speaking to your network provider to see if there is anything they can do.
