Ullaspj, there is an awesome app on Googles Play Store called Plan B. This app will find your phone... I Guarantee it. The only requirements are that your phone is actually on of course, and that you have a google account on there.... Follow the steps below to continue!
1. Naviagate to google.com, and sign in WITH THE SAME GOOGLE ACCOUNT THATS ON YOUR PHONE. It MUST be the same, because what we are gonna do is send the app to your phone using your PC.
2. Once Signed in, click up at the top on he iten that reads "Play"
3. Go back to the searh bar and type in "Plan B", and hit enter.
4. Make sure you read all the information, then download and itll send the app t your phone.
After that, the process is basically, get people to text the word LOCATE to your phone. everytime someone does, the phone sends an automatic email to your gmail account listing your phones GPS coordinates. simply copy and paste into google maps, and BAM. Theres your phone.
You know what, im a nice guy. Here:
