Remarks

Set whether a subscription is opportunistic, that is, whether the network it connects to has limited coverage. For example, CBRS. Setting a subscription opportunistic has following impacts: 1) Even if it's active, it will be dormant most of the time. The modem will not try to scan or camp until it knows an available network is nearby to save power. 2) Telephony relies on system app or carrier input to notify nearby available networks. See TelephonyManager#updateAvailableNetworks(List, Executor, Consumer) for more information. 3) In multi-SIM devices, when the network is nearby and camped, system may automatically switch internet data between it and default data subscription, based on carrier recommendation and its signal strength and metered-ness, etc.

Caller will either have android.Manifest.permission#MODIFY_PHONE_STATE or carrier privilege permission of the subscription.
