eSIM is going to be a super important thing moving forward, as all the new iPhones 14 models are eSIM activations only, so I really want to make sure we're capturing and showing all of the eSIM information correctly.
Where are you seeing the eSIM phone number as nil? I just checked an iPad I have which is eSIM activated, and I see the eSIM information (including phone number) once I click on the device and view its device details in Dashboard. I obfuscated the values, but Phone number, IMEI, and EID all exist for me:
If you are not seeing this, but have an active eSIM, please open a support case so we can review the device's activation / device refresh information to make sure it is captured/showed properly. Thank you!
