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. <key>ServiceSubscriptions</key> <array> <dict> <key>CarrierSettingsVersion</key> <string>61.0</string> <key>CurrentCarrierNetwork</key> <string></string> <key>CurrentMCC</key> <string>450</string> <key>CurrentMNC</key> <string>08</string> <key>EID</key> <string>blah blah</string> <key>ICCID</key> <string>blah balh</string> <key>IMEI</key> <string>blah blah</string> <key>IsDataPreferred</key> <true/> <key>IsRoaming</key> <true/> <key>IsVoicePreferred</key> <false/> <key>Label</key> <string>Provisioning</string> <key>LabelID</key> <string>00000000-0000-0000-0000-000000000000</string> <key>PhoneNumber</key> <string></string> <key>Slot</key> <string>CTSubscriptionSlotOne</string> <key>SubscriberCarrierNetwork</key> <string>iPad</string> </dict> </array> 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. <key>ServiceSubscriptions</key> <array> <dict> <key>IMEI</key> <string>blah blah</string> <key>Slot</key> <string>CTSubscriptionSlotOne</string> </dict> <dict> <key>EID</key> <string>blah blah</string> <key>IMEI</key> <string>blah blah</string> <key>Slot</key> <string>CTSubscriptionSlotTwo</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?
