When iPhone is connected to Wifi, does Wifi takes priority over 3G/4G for
data (movies, browsing Net & Whatsapp) usage?
My kid's data plan (3G/4G) tends to get exceeded when she watches movies/videos
at home but we have free broadband Wifi at home.
When she's at home, she only needs Wifi (for browsing the Net, watch movies &
Whatsapp) but very often, her often got disconnected from Wifi & she does not
notice it, thus incurring lots of 3G/4G bills when watching movies on Internet.
Is there any way to turn off the 3G/4G automatically when her connection to
Wifi while at home is dropped? Any freeware to do this?
Purpose is to reduce the data usage while at home. Very often, just rebooting the
Wifi broadband router or re-establishing connection to the Wifi service on her phone
will do the trick but she often did not pay attention to it when the Wifi link is dropped
