Thank you. I started by reaching out to the manufacturer support but guess what? No response. Nothing!
I managed to experiment my way to simple sort-of satisfactory settings but wanted to share the experience for those not stubborn and persistent like me, because it really takes time and effort get though it all.
I just need to track a vehicle that several users share when needed, no sensors, automated messages, surveillance etc.
Repeatedly running RCONF (everybody with SMS capable devices should try) to see what changed along the experimenting, only to see that RCONF doesn’t report everything from the SinoTrack either.
Realizing the problem, testing and cheking SIM + device + telecompany to at all understand why every single information in the manual or online was wrong.
Then installing their app and testing the integrated SMS management feature, to learn that this wasn’t working either.
Then working their web access to the device to no avail.
App + web interfaces are poorly translated but even after trial & error, it still didn’t make sense. Selected settings not to be confirmed in way.
Conclusion: If users are looking for no fuzz, plug ’n play solutions, alternatives should be considered before spending.
