It is free, simple and easy to use.

Can be PIN protected so only those who know the PIN can find out the location. If PIN protection is enabled then the query SMS needs to inlude the PIN. eg: fm?1234.

If GPS is not available then FindMeSMS replies with link that includes the CellID (telephone tower) information, and clicking on the link in the SMS message will bring up a map showing location of the phone tower with which the phone is communicating.

Does not drain the battery. Only starts when SMS received, and stops running after sending response. Restarts automatically if phone is power cycled.

Person whose location is queried is not alerted that their location is queried.

Usage:
- Install FindMeSMS on the Windows Mobile phone to be tracked.
- Send SMS to the tracked phone. SMS message must have this code in it: fm?
- Receive SMS reply. Click on the link in SMS reply to display map showing location.

Note:
Developed on HTC Touch Diamond 2, so not sure how the admin screen will look on lower res devices...
