Trying to make it work on mine also - atm best results are on:
But still update history looks random, it was set 30s, need to check it on vehice - mayby gt02a is sleeping when no position change is made.
On GT02A/LEGNACY settings it was offline.
UPDATE: I have make it to work - GT02A has two timers:
Info from other site:
Turns out there are two timers a moving timer and a static timer and these are set with simple SMS commands such as:
730#20# for moving updates at 20 seconds and SUP#5# for a static update of 5 mins.
