In iOS 9, Apple added a new feature called Wi-Fi assist. When you’re using a bad Wi-Fi connection, it switches over to cellular data. (Typically, your phone switches over to a cellular connection when Wi-Fi becomes unavailable. With Wi-Fi Assist, it kicks in when Wi-Fi meets what it deems as a “poor” connection.)  To avoid unexpected data overage charges we recommend turning this feature off.

How to Turn off Wi-Fi Assist

Wi-Fi Assist will automatically switch to the cell network for data if it detects an inconsistent Wi-Fi signal. To turn off this feature:

  1. Tap the Settings app
  2. Tap Cellular Data & scroll to bottom
  3. Toggle Wi-Fi Assist switch to the right of the app for which you wish to disable it to off.
    The switch will become grayed-out when toggled off.
