Not sure if it's free, but we used to use a program at work called "InfoRad" it worked with pagers, but I'm pretty sure you could use it with cell phones too. Let me do some googling and see what I can find.
ETA: Sorry, looks like InfoRad actually costs money to download. Posted Via AR15.Com Mobile |
