Can i reset my iphone without having it on me?

I just lost my i phone 6 i was wondering if there's a way that i can reset it from itunes without having the phone on me. Is there?

You can if you have activated Find My Phone on iCloud.

Yeah FMI through iCloud is the only way. Of course, your phone must have Internet access (either Wi-Fi or mobile data). But once you remotely erase your phone, you won't be able to track it.

Probably

Rather than reset it, you can remote lock it in "Lost Mode" - which leaves it still locateable.
