After looking for a GPS tracker, this one has lots of features, is inexpensive and does not require a contract with a company for operation. For $30 seemed to be a good deal. I was indeed impressed by what arrived in the mail from Amazon. It appears sturdy and has a good looking wiring harness and other accessories. More review to follow.
My problem is this. I had trouble getting the H2O SIM card in Dallas. I got a SIM card on my AT&T account for $10 per mo which is shared by two other phones with unlimited minutes, texts, etc. H2O is cheaper but I just want to get it working. Dallas had excellent AT&T coverage by the way.
When I try and activate the device:
- antennas in place
- 12V applied to the red and black
- Mine does not have a backup battery switch to throw . . . don’t know what they are talking about.
It appears to power up in GPRS mode only, designated by the red blink every 3 seconds alternating with green, which indicates a good GPS signal. BUT, it never goes into GMS mode with the fast blink. When I call the phone number or send it messages it does not respond in any way.
I’m out of ideas. How do I troubleshoot from there. I have called AT&T and the SIM is indeed active and it works in another device as well.
Another minor detail is that mine does not have a backup battery switch or any switches on it as described in the installation instructions. Is this an option on some models?
Here is a good youtube on the device showing all functions. Mine behaves the same except that is has a slow rather than the fast blink shown and it does not respond to texts.
Any help?
