Once switched on, Wi-Fi Assist will switch to cellular network so you can enjoy a seamless connection. While this may sound all good, it poses a problem to those who are not on an unlimited data plan.
By default, Wi-Fi Assist is activated on a new iPhone device or when you upgrade an older device to the latest iOS update. So if you have been wondering why you have been incurring overage charges for mobile data, the culprit may be Wi-Fi Assist.
To deactivate Wi-Fi Assist, follow these tips:
- Go to Settings > Cellular
- Scroll to the bottom of the menu
- Switch off Wi-Fi Assist
