I use an H2O wireless card with text and phone, but no data. Works fine. One note, it is easiest if you activate the card with H2O in a phone, not in the tracker. Then you can be completely sure that it is fully functional.Anyone know of any SIM card requirements to get this unit up and going? Services that must be enabled etc?
I feel like there really isn't much to troubleshoot here - especially since it works with one SIM and not the other.
Again, any suggestions are appreciated.
