Hi there and welcome
As long as you did not turn off find my phone, and its still powered on and with internet, then go on your computer to
Sign in with the same Apple Id you used on the phone and it will then show you its location if its possible.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
