Disabling Wi-Fi Assist
Wi-Fi Assist is an iPhone specific application that lets you automatically pop over to cellular data if you end up on a Wi-Fi network with a poor connection. That's great for maintaining your Netflix stream or Facebook browsing, but not so great for your data usage.
Here’s how to turn Wifi Assist off:
1. Launch the Settings app.
2. Tap Cellular.
3. Scroll down to the bottom of the screen and switch the Wi-Fi Assist toggle to Off.
