I have Moto E connected to plusnet home WiFi but still being charged for internet usage with EE pay as you go?
The menu is'nt the same as the moto G which people have descibed a fix for .
Make sure that data connection is turned off when not in use. If you don't, your phone can accidentally use data when Wi-Fi network is unavailable.
You can find the setting here: Settings > More > Mobile networks
