Carrier Do I need to turn off the 4G when on wifi?

Well the title say it all. When i get on wifi it should over take the connection even if the 4G still on right?

Do you turn it off?

Should i?

It should always default to wifi over cellular. There shouldn't be any need to disable it.

Actually, its may use 4G when connect to wifi. iOS uses multipath tcp.

I always turn off cellular when using wifi. I'm on a limited data plan and can't afford to lose that data if/when wifi disconnects.

If you sync a lot of data in the background I definitely recommend leaving it off when in places where wifi is unstable.

I turn it off... It takes five seconds and after that I don't need to second guess it. In 2012 they had a big problem where it was using an unnecessary amount of cellular data.

Where I work there are WiFi dead spots and cellular data kicks in when that happens. So yea, to be on the safe side turn off your cellular when you want to be connecting via WiFi.

Once I was also streaming video over WiFi and thought I had closed the app. I then went out with my iPad for some coffee and the streaming app was still running and switched over to cell data.

They should add an option that would turn on 4G when outside home


Thx all for your opinion
