EID missing and Cellular/Mobile Service is greyed out

iPhone 15 — EID missing and Cellular/Mobile Service is greyed out

Hi everyone,

I’m having an issue with my iPhone 15 and would really appreciate some help.

My iPhone 15 model supports eSIM, and I have already confirmed that it is an eSIM-supported model. However, I’m facing two problems:

  • The EID number does not appear under Settings > General > About.
  • Cellular/Mobile Service is completely greyed out, so I cannot even open the Cellular settings or add an eSIM.

I’ve checked that the phone is an eSIM-supported model, but the EID is still missing and the Cellular option is inaccessible.

Has anyone experienced the same issue with an iPhone 15? If so, were you able to fix it? Could this be a software/iOS issue, a carrier issue, or possibly a hardware/logic-board problem? If it is one of these issues, how can I fix it or get it properly diagnosed and repaired?

Any suggestions or troubleshooting steps would be greatly appreciated. Thanks!

Hi, please contact our cellular service provider and explain the issue to a member of their support team. The devices eSIM most likely needs to be reporvisioned by the carrier. In my experience most Over The Air (OTA) provisioning fails about half the time and you'll need to take the device to your carriers service to have it done.

Yeah, I went to them, and they said it’s an issue with the phone and Apple and has nothing to do with them. They didn’t know about this issue either.
