Many users try to turn on mobile data during Airplane Mode by using hidden dialer codes.
But on most modern Android phones, these codes don’t work anymore — the menu doesn’t open, or the feature is blocked by the manufacturer.

This app unlocks advanced network options that usually appear through secret dialer codes — without needing the codes at all.

Today, I’ll explain how the app works and how you can use it to try enabling internet in Airplane Mode.
