Ok, I was getting the unit set up last night, and indeed it needs a sim card and phone plan for it to work. It must be activated and set up for gsm/gprs communication. Yes! I'm kicking myself right now I had misread information about no fees. So, I used my own cellphone sim card and it relays info fine. I'm trying to get the IP address with tracking software linked up to the unit, so I can get coordinates.

So, It will be anywhere around 380.00-600.00 per unit. Then you will have to get a sim card with gsm+gprs communication from any cellphone dealer with plan for each unit.
Anybody know where I can get Sim cards or work for a cellphone store,lol?
More info soon as I troubleshoot this.
