Wi-Fi Assist is designed to help when you have a poor Wi-Fi connection. When the Wi-Fi Assist feature is turned on, it will automatically use cellular data when Wi-Fi connectivity is poor. However, you are increasing the use of your cellular data, often without realizing it; this means you might be at risk for additional cellular data charges.
