How to turn a iphone 5c off without going on it if someone has it?

My parents took my phone and i need to turn it off and i'm not usre if that text works anymore how do i get it to shut down

There's no way to turn it off. You have to wait until the battery runs out

What an idiot. Preston is right. There's no way to remotely turn it off.

The closest you'll get is by erasing your iPhone through iCloud Find My iPhone. However, this will make your parents very suspicioius.

If you're old enough to have a phone, then you're old enough to deal with the consequences of your actions.

If you have "Find my phone", from a computer you can lock it. But this only applies if you actually have FMP activated on your phone.
