How to Locate an SMS Sender

1. Visit the site Trace Text. Enter the number you got the text from in the main textbox on the site. Click 'Search Now!' This will give you the number's general location. You'll have to purchase a subscription to trace it back to the exact address.
2. Download and install the app ReverseLookup for your Android phone. This application lets you look up a phone number that has tested you directly from your android phone and trace where it came from. This version of the app is free to use.
3. Visit the website Ugux. This site is completely free to use, and allows you enter the number that texted you, area code first, into the three boxes on the site in order to search the online public directory for a trace on the number.
