You have to Sign in first to the Android Device Manager website at www.google.com/android/devicemanager then ensure that your current mobile device is selected.
From this site, one can see the near location of that device. You can also lock the phone, erase data, or ring the device. Your phone will ring for up to five minutes even if it’s on silent.
After that if there is a need to quickly find Mobile phone in the future, Google can help you to find it on “find my phone.”
