Hi @Sudhan_23, let me see if I can help here!
If you have lost your phone you can try locating the phone using Googles service called Find My Device provided that you have a Google account synchronized in the phone. Simply log in to the webpage below using your Google credentials and you should be able to get a geographical pinpoint of the phones position provided that the phone is still turned on and has an internet connection.

I hope that helped!
