I am checking the response of DeviceInformation Command to collect network information from iPad.
On iPad(iPad Pro 11, M4) devices that use WiFi without inserting Usim or Esim, network values such as CurrentMCC and ICCID are received in response to the DeviceInformation command.
cf.)Even though it may be garbage value, I blurred the unique information just in case.

This is a bit weird. If I collect the same information from an iPhone(iPhone 15 Pro Max) that only uses wifi and does not use Usim or Esim, it does not respond with values like ICCID, CurrentMCC, etc.

<array>
<dict>
<key>IMEI</key>
<string>blah blah</string>
<key>Slot</key>
<string>CTSubscriptionSlotOne</string>

<string>blah blah</string>
<key>IMEI</key>
<string>blah blah</string>

</dict>
</array>
I'm confused by the network information collected. Is there a reason why the collected network information of iPad and iPhone are different?
