Till iOS 10.3, control center did not allow you to toggle mobile data from control center. Thus, if your phone was being handled by someone else, he could not switch off mobile data without locking the phone.
However, with iOS 11, mobile data switch has been added to the control center and now anyone handling my iPhone with iOS 11 can switch off mobile data. This also compromises Find my iPhone feature in a big way.
How do I prevent somone from switching off mobile data from control center?

Do not worry, it is still possible.The way is a little long. Just follow these steps:
Now, the control center widget will not toggle mobile data and you can still go to settings and disable it while the iPhone is unlocked; just like you were doing till iOS 10.3
