How do I set an iphone to only use data with wifi?

[jean901]

I'd like to set up my sons iphone to only access data when wifi is available. He is using way too much data. I'm sure there is a simple answer, can anyone help?

I just found out that all you have to do is go to "Cellular" under settings and turn off the cellular data. I knew there had to be an easy fix!

Family base is another option.  It turns off their data when they reached their limit    Also at certain times it is especially good for share data.

Family Base is best. Turning cellular off, he can turn it back on. And cellular is not in restrictions.
