How to turn off Wi-Fi Assist on iPhone

Go to Settings > Cellular (or Mobile Service), scroll to the bottom and turn off Wi-Fi Assist. The phone stops jumping to cellular when the Wi-Fi is weak.

How to do it

  1. Open Settings > Cellular. If your phone says Mobile Service or Mobile Data, open that instead.

  2. Scroll to the bottom and turn Wi-Fi Assist off.

  3. Turn it back on later if you would rather the phone abandon a dead network than sit on it.

With Assist off, a weak network stays weak. Pages load slowly instead of jumping to cellular. That is the trade.
