Note, the registration subscription ID comes from [TelephonyManager](/reference/kotlin/android/telephony/TelephonyManager) object which registers TelephonyCallback by [TelephonyManager.registerTelephonyCallback(Executor, TelephonyCallback)](/reference/kotlin/android/telephony/TelephonyManager#registerTelephonyCallback(java.util.concurrent.Executor,%20android.telephony.TelephonyCallback)). If this TelephonyManager object was created with [TelephonyManager.createForSubscriptionId(int)](/reference/kotlin/android/telephony/TelephonyManager#createForSubscriptionId(kotlin.Int)), then the callback applies to the subscription ID. Otherwise, this callback applies to [SubscriptionManager.getDefaultSubscriptionId()](/reference/kotlin/android/telephony/SubscriptionManager#getDefaultSubscriptionId()). \nRequires [android.Manifest.permission#ACCESS_FINE_LOCATION](../Manifest.permission.html#ACCESS_FINE_LOCATION:kotlin.String)\n\n| Parameters ||\n|------------|------------------------------------------------------------------------------------------------|\n| `location` | [CellLocation](/reference/kotlin/android/telephony/CellLocation): This value cannot be `null`. |"]]
