Hi Indra_10, do you have your e-mail logged in in your lost phone? If so, search Android Device Manager and log in there in another device, example borrow Android phone (doesn't have to be Android I think) from who you think will borrow their phone to you. When you have logged in, you can option (ring, lock, shutdown) your phone and above the option there is a Google Map thing above that tells you where is your phone.
And if your phone is turned off, there might be a little chance for your phone to be located.
I hope you get the phone As Soon As Possible! Good wishes to you!
I add only that on the loss of a mobile device, the first thing to do is to notify the Service Provider because they will expect you to pay for any calls or mobile data the thief or the finder is using.
They may also be able to tell you where the device was when it was last used and that information might be useful.
