Can you find an iPhone with disabled location service?

My sister lost her iPhone and we r trying to track it down but she switched off her location service (to save battery she said) when she still, had her iPod.
We were trying to send message to her iPhone with find my iPhone app which I doubt who ever found it will get it because it needs Wi-Fi and her iPhone is locked.

Since her battery was really low, I dunno if it was still on. Maybe it shut down because of low battery:/

Is it possible to find it? It URGENT we're on a trip and leAving tomorrow. There's like 2000 pictures In that iPod and we have to get it back Please Help

Try call Apple to see if there's a way. 800-APL-CARE (800-275-2273). Hope you find it!
