will the internet experience on my phone be slower on wi-fi?

In the majority of cases, no. Wi-Fi usually provides a faster Internet connection and lower latency (speed to respond), resulting in a better experience for viewing data intensive content like video streaming, gaming, and web browsing; however, it is possible for Wi-Fi hotspots to be congested and provide a slower Internet connection.  If this occurs, WeFi Pro will automatically move the data connection back to the Cricket cellular network.
