Offer the user a network slicing upsell

5G network slicing gives carriers the ability to provide network performance boosts for specific use cases. This guide explains how an app can trigger the network slicing upsell UX flow and request a premium connection if the user decides to purchase one.

The UX flow shows the user a notification that opens up a carrier
       websheet where they can complete the purchase.
Figure 1. An example of the upsell UX flow.

Declare premium capability intents

In order for your app's request for a network capability to be honored, your app must declare its intent to request that capability in the app manifest. Otherwise, the network request fails throwing a SecurityException.

To do this, your app must declare the PackageManager.PROPERTY_SELF_CERTIFIED_NETWORK_CAPABILITIES property in the AndroidManifest.xml file and include a corresponding XML resource file.

A capability declaration in the manifest file looks like this:

<property android:name=""
          android:resource="@xml/network_capabilities" />

The corresponding network_capabilities.xml resource file looks like this:

<network-capabilities-declaration> xmlns:android="">
    <uses-network-capability android:name="NET_CAPABILITY_PRIORITIZE_LATENCY"/>

Trigger the network slicing upsell flow

This code example demonstrates how to trigger the upsell flow and request the purchased premium capability.

Context mContext;
Network mNetwork;

public void purchasePremiumCapability() {
    TelephonyManager tm = mContext.getSystemService(TelephonyManager.class);
    int capability = TelephonyManager.PREMIUM_CAPABILITY_PRIORITIZE_LATENCY;
    if (tm.isPremiumCapabilityAvailableForPurchase(capability)) {
        tm.purchasePremiumCapability(capability, Runnable::run, new Consumer<Integer>() {
            public void accept(Integer result) {
                Log.d("Purchase premium capability result: "
                        + TelephonyManager.convertPurchaseResultToString(result));
                switch (result) {
                    case /* success or already purchased */:
                    case /* temporary failure */:
                        // TODO: wait and retry
                    case /* hard failure */:
                        // TODO: handle failure
                        Log.e("Unknown purchase result: " + result);
    } else {
        Log.e("Premium capability is not available for purchase.");

public void requestPremiumCapabilityNetwork() {
    ConnectvityManager cm = mContext.getSystemService(ConnectivityManager.class);
    NetworkRequest request = NetworkRequest.Builder()
    cm.requestNetwork(request, new NetworkCallback() {
        public void onAvailable(Network network) {
            Log.d("Application can now use the network with the premium capability.");
            mNetwork = network;

        public void onLost(Network network) {
            Log.d("Premium capability network is no longer available.");
            mNetwork = null;
            // TODO: clean up anything relying on the premium capability network

The following sections describe the steps involved in this process in greater detail.

Step 1: Verify if premium capability is available

Call the isPremiumCapabilityAvailableForPurchase() API method to determine whether the selected premium capability is available. This method returns true if the capability is available for purchase from the carrier using the upsell notification workflow.

Step 2: Initiate the upsell notification flow

After confirming that the premium capability is available, your app should call purchasePremiumCapability() to initiate the upsell notification flow. If the user has not already purchased the specified capability and all preconditions are satisfied, then the platform shows the user a notification to let them know that performance boost options might be available from their carrier. If the user taps the notification, the platform opens the carrier's webview so that the purchase process can continue.

The parameter callback passed to purchasePremiumCapability() returns a result code for the purchase request.

The result codes PURCHASE_PREMIUM_CAPABILITY_RESULT_SUCCESS and PURCHASE_PREMIUM_CAPABILITY_RESULT_ALREADY_PURCHASED represent successful results where your app can proceed to requesting the selected premium capability.

The result codes in the following list represent failed purchase requests. See the API reference to learn more about them.

Step 3: Request the purchased premium connection

If the upsell notification flow returns a successful code (PURCHASE_PREMIUM_CAPABILITY_RESULT_SUCCESS or PURCHASE_PREMIUM_CAPABILITY_RESULT_ALREADY_PURCHASED), your app should use requestNetwork() to request a network that satisfies the requested capability. Note that when you build a NetworkRequest object, the capability that you add is not the same capability that you pass to the TelephonyManager APIs in the earlier steps. The following table maps the constants from the TelephonyManager class to the corresponding constants in NetworkCapabilities.

TelephonyManager constant NetworkCapabilities constant

If the purchase request fails, your app should request and use the default network instead. There is no automatic fallback behavior if the premium slice request cannot be fulfilled.
