*** Does not work on Verizon *** 3G & CDMA Support is limited by Android, not by the application *** CDMA requires Eclair ***

Works best with 2G GSM. 3G/CDMA support is very limited.

Please understand what this tool does and does not do before you rate it. If you are not interested in the esoteric details of how the cellular network works, please do not download this app, it will frustrate you and be a waste of your time. Please check website for details.

I have reports that Verizon now blocks locations. Other providers may do same. Bummer. If your provider blocks, please be considerate and don't downrate the app. Not my fault.

Yes it is a battery hog - it needs to be.

Froyo problems? Tested with HTC Desire 2.2, Galaxy S and Galaxy Tab. I do know that it's failing on some devices through. New release coming soon.

    The background of the bottom part of the display is dark gray and the text is black. This very bad choice. Make the font white or change the background to lighter color.

    Over here the only use for GSM is mobile terminal devices with low bandwidth. So why no UMTS/LTE support in this day and age?

    Worked great on Nexus 1 and Atrix 4G. Doesn't work on Moto X running Kit-Kat.
