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()).\n\n| Parameters ||\n|-------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `direction` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html): Value is [android.telephony.TelephonyManager#DATA_ACTIVITY_NONE](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_NONE:kotlin.Int), [android.telephony.TelephonyManager#DATA_ACTIVITY_IN](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_IN:kotlin.Int), [android.telephony.TelephonyManager#DATA_ACTIVITY_OUT](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_OUT:kotlin.Int), [android.telephony.TelephonyManager#DATA_ACTIVITY_INOUT](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_INOUT:kotlin.Int), or [android.telephony.TelephonyManager#DATA_ACTIVITY_DORMANT](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_DORMANT:kotlin.Int) |\n\n**See Also**\n\n- [android.telephony.TelephonyManager#DATA_ACTIVITY_NONE](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_NONE:kotlin.Int)\n- [android.telephony.TelephonyManager#DATA_ACTIVITY_IN](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_IN:kotlin.Int)\n- [android.telephony.TelephonyManager#DATA_ACTIVITY_OUT](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_OUT:kotlin.Int)\n- [android.telephony.TelephonyManager#DATA_ACTIVITY_INOUT](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_INOUT:kotlin.Int)\n- [android.telephony.TelephonyManager#DATA_ACTIVITY_DORMANT](/reference/kotlin/android/telephony/TelephonyManager#DATA_ACTIVITY_DORMANT:kotlin.Int)"]]
