Cell Phone Tracking

Profone GSM Tracker

Track down mobile devices' location online free of charge by cell tower triangulation using LAC (Location Area Code) and CellID from PC or Smartphone. I now am proud to announce that Profone GSM tracker is used by some global 500 companies, police departments and various APP developers for both Android and iPhone OS.

Got LAC in Hexadecimal? Try the converter. Make converts between GPS coordinates and address, try this. Cell towers in database more than doubled, now 40,962,709 and counting!

What is Profone GSM tracker

Profone GSM tracker is an online location service based on cell tower triangulation technology which uses MCC, MNC, LAC and CellID to determine the position of a mobile device.

What is MCC

MCC stands for mobile country code, it's an unique three digit code assigned and managed by ITU to identify the country which a mobile subscriber belongs. For example, MCC 310 is used by US.

What is MNC

MNC stands for mobile network code, this unique 2 or 3 digit code is used to identify a carrier together with MCC. For example, you see 310-090, you know it's AT&T in USA.

What is LAC

LAC stands for location area code, it's used by carriers to identify a location area where the cell towers are located. However it's not unique, different countries and carriers could have the same LAC. In general, you know MCC, MNC and LAC, you could know the approximate location of a cell phone.

What is Cell ID

Cell ID is used to identify a base transceiver station within a LAC. A cell tower could have more than one (1) cell id. You know a Cell ID, you know the location of a cell phone. You know more than 3 cell towers, you can pinpoint a cell phone.

How accurate is my GSM tracker

It depends on how many cell towers you can find in your area. In general, the density is higher in the urban areas especially at downtown. While in rural areas, where there are fewer cell towers, the result is less accurate. I have done a few tests in area where I could find more than three (3) cell towers, the margin of error is within 30 meters upon using my improved algorithm.

Profone GSM tracker now has over 40 million of cell towers in database exclude China, it supports GSM, CDMA, UMTS and LTE base stations.

What's new!! Now you can view the neighboring cell towers if there's more than one base station found in that area. More info here.

I am not responsible for any possible errors. You can get in touch with me via the about page or follow me on Facebook, feedbacks are appreciated.

What's New!! Upon some hardware and software uprade and optimizations, I am able to increase the speed for all users. According to my test, the page load time has been reduced dramatically by up to 2/3.

What's New!!! Profone GSM tracker API is now live, coporate users can use this API to track cars, fleets and shipments. Please drop me a line at znxhw#hotmail.com or check this out if you need it.
