I removed your IMEI number to prevent someone else using it to trace your phone. I also took down the phone number because if you get it back, you'll get Spam calls from all over the world when teh number is sold.
As soon as you can, contact your Service Provider because the finder or thief could be running up a big bill for calls and mobile data and it's down to you to pay for it all.
Notify the loss and ask where it was when it was last switched on. That might help you find it.
