Can I Check My Kids Web Browsing With AT&T?

My kids have iPhones and I want to know if there's a way I can check their web browsing, without looking in their phones

Why would you buy them a phone if you aren't sure about their web surfing?

No you can't

Ther is but you need a computer.

sense there phones have the sifari app.

Just open sifari on PC or MAC. Look at the recent searches and there serches will be there.

Or you could open the sifari app on there phone when there not around, tap "search" and there recent searches will pop up in the bottom.

Yes, if you have an iPhone than you can download the app called "team viewer". This allows you to use the internet with them and look at what they are doing now and what they did before (unless your kids are extra smart and took out parental blocks and use the incognito window from Google Chrome, which doesn't save history, which also means that you can only look at it while they are using the incognito window).
