George and I have installed the new Meitrack T333 3G tracker.
It works pretty good.
They've changed the communication protocol a bit, so I have had to write code for the tracking website to suit.
I have my old tracker available cheap if anyone wants it. It will be good on the Telstra network until the end of 2016.
If you don't care about using Telstra, or don't want to use Telstra, the other telcos still have 2G networks also, which could be around for longer still.
I also still have one brand new in the box that I had as a spare. I think cage had dibs on it, but not sure if he still wants it.
