I’m trying to open mobile data settings on Android API 33 and for that to happen, from an activity I run the following code:

Intent roamingIntent = new Intent(Settings.ACTION_DATA_ROAMING_SETTINGS);
try {
  startActivity(roamingIntent);
} catch (Exception e) {
  // failed
}

It works fine on many brands of Android phones that I have tested, but when I tested on Google Pixel 5, Google Pixel 6 and Google Pixel 7 the mobile data settings page is not opened and I get the following error:

Documentation:

public static final String  ACTION_DATA_ROAMING_SETTINGS
Activity Action: Show settings for selection of 2G/3G.
In some cases, a matching Activity may not exist, so ensure you safeguard against this.
Input: Nothing.
Output: Nothing.

I catch the exception if that is what they mean with “safe guard”, or should I run some intent matcher to check if any app handles the intent first? However, it still would not help in showing the data settings page.
