S5

I found my brother's old s5 

It says I'm using data when I'm using apps with wifi?

You can turn off mobile data in connection settings.

As long as the antenna can detect a cell signal, it will display relative signal strength, even without a SIM. This doesn't mean that the phone is using data.
