How can CTTelephonyNetworkInfo().serviceSubscriberCellularProviders return nil? Under what conditions (hardware/software) can CTTelephonyNetworkInfo().serviceSubscriberCellularProviders return nil? The variable is optional so I assume there's a case but I can't seem to figure out the conditions. Thanks for any info. App & System Services Networking Core Telephony 2 0 860 Oct ’22
