It does that because there is no need for a 4G connection when you have Wifi. Your phone prioritizes the Wifi connection because it saves your mobile data (in case you have a data cap)

Well actually, if you leave both Data and WiFi turned on and you have a WiFi connection, you'll normally only see WiFi activity. But, if you do something that actually requires a data connection, such as download an MMS with an attachment, you'll see the data connection turn on briefly and then go off.
