K-Chiing shows money savings, but I've been on WiFi all the time.

K-Chiing presents an estimate on savings taking the assumption of the money costs. Unfortunately, it is not possible to access the status of the network (wifi, roaming, 4G) on every platform, so we use an orientative figure that shows how much money would've been saved if the device had been on roaming. However, data savings is a real value.
