Hi Team,I work for one of the networks. I got eSIM entitlement for dev/distribution profile.Done the below changes to check the device support eSIM or not.Added below changes in <appname>.entitlements <key>com.apple.CommCenter.fine-grained</key> <array> <string>public-cellular-plan</string> </array>info.plist<key>CarrierDescriptors</key><array><dict> <key>MCC</key> //Mobile country code <string>’mnc value’</string> <key>MNC</key> // Mobile network code <string>’mnc value’</string></dict></array>I am checking the device support eSIM or not. func isDeviceSupportESIM() -> Bool { if #available(iOS 12.0, *) { let plan = CTCellularPlanProvisioning() if plan.supportsCellularPlan() { return true } return false } return false }Method always return nil.
